RICHMOND HILL RESOURCES PLC: The Martello Gold Project

A High-Grade Gold Exploration Opportunity

Wabigoon Greenstone Belt · Ontario · Canada

‍

‍BROKER NOTE BY JONATHAN PLANT - August 2026

‍

Richmond Hill Resources plc (“RHR”) has repositioned itself around the Martello Gold Project in Ontario, a consolidated, road-accessible gold exploration package in the Wabigoon Greenstone Belt with historic high-grade production, multiple documented occurrences and a credible district-scale exploration thesis. 

Martello now comprises 145 mining claims covering approximately 5,685 hectares, following the acquisition of the original Martello claims, the adjacent Bartlett claims and the low-cost Esler claims. The significance of this consolidation is that the ground appears to bring together historically fragmented gold occurrences within a single structural framework, allowing RHR to evaluate the project as an integrated mineralised system rather than as a series of isolated prospects.

The principal investment case is not based on a blind grassroots discovery. Gold has been documented across the property for more than a century, including historic production from Sakoose at approximately 15 g/t Au and additional occurrences such as Maw and Tabor. The key questions are therefore scale, continuity, geometry and ultimately whether modern exploration can define a compliant resource of meaningful size.

RHR’s recent technical work has materially improved that question set. Historical data compilation, drone magnetic surveying, 3D magnetic inversion and the maiden Tabor drill programme have helped identify and rank seven priority targets across the project. Sakoose is the leading target because it combines historic high-grade production, an interpreted strike extent of more than 1.4 kilometres, multiple subparallel structures and several subordinate prospecting targets around the old workings.

The project’s infrastructure profile is a central advantage. Martello is located approximately 45 kilometres south-east of Dryden, Ontario, with road access, nearby services, available crews and a lower-cost operating environment than remote, helicopter-supported Canadian exploration projects. This matters because RHR is a micro-cap explorer and the value creation path depends on maximising drilling efficiency while limiting unnecessary dilution.

Near-term catalysts include permit progression, field validation at priority targets, assay results from the 35 rock-chip samples collected from Sakoose, Maw and Church Lake during the July 2026 field programme, and the proposed next phase of drilling focused on Sakoose. Positive results would support the district thesis and could justify a re-rating from a historic, high-grade exploration story toward a more systematic resource-definition opportunity.^M14 There was a small uptick in share price on this field validation work showing that the market is watching.

The principal risks remain exploration risk, funding risk and dilution. The historic resource and production data are not compliant with modern reporting standards, and the interpretation of structural continuity must be confirmed by drilling. However, the combination of a consolidated land package, historic high grades, modern targeting and favourable logistics gives Martello a credible route to value creation if RHR can demonstrate continuity across the priority structures. We tweak the 18month share price target up to 12p to reflect the timeline of works required but also the enhanced value opportunity in Martello and potential read-through across the portfolio.

‍

Investment Case

At first glance, RHR may appear to be a conventional pre-discovery explorer: a micro-cap company with a project that requires repeated rounds of drilling, capital raising and geological interpretation before a compliant resource can be defined.

That framing understates the quality of the starting point. Martello is not a blind grassroots concept; it is a consolidated gold system with historic high-grade production, multiple documented occurrences and a modern technical programme now designed to test whether those occurrences form part of a coherent district-scale structure.

Sakoose provides the strongest evidence base. Historic records indicate approximately 3,900 ounces of production at roughly 15 g/t Au, while the wider Martello footprint includes additional occurrences that support the possibility of repeated mineralised structures rather than a single isolated vein.

RHR has begun to convert that historic record into a modern exploration framework. Critical Discoveries Ltd has been engaged to rationalise legacy data, integrate the drone magnetic survey and 3D magnetic inversion model, and translate those inputs into ranked drill targets.

The result is a more disciplined exploration case: seven priority target zones have been identified, with Sakoose ranked first because it combines historic high-grade production, an interpreted strike length of more than 1.4 kilometres, structural complexity and multiple subordinate targets around the old workings.

The maiden Tabor drilling should be viewed primarily as calibration work rather than as a resource-definition programme. It validated geological controls, tested extensions to known mineralisation and improved the understanding of vein geometry, all of which helps sharpen the next phase of drilling.

The investment case therefore turns on definition rather than discovery alone. The central questions are whether RHR can demonstrate continuity, scale and geometry across the priority structures, and whether that work can support a compliant resource of meaningful size.

Martello’s logistics strengthen that case. Road access, proximity to Dryden, local services and lower mobilisation costs mean the company can test more metres per pound raised than a remote, helicopter-supported explorer, reducing the dilution burden that typically limits micro-cap exploration stories. 

Near-term value creation now rests on a simple sequence: assays from the July 2026 sampling, permit progress and the proposed Sakoose-focused drill programme. Potential positive results could strengthen the case for Martello as a connected gold system, not just a collection of historical showings.^M14

‍

Geology & History

The geology section can be read simply: Martello is not a blank-sheet prospect. Ontario Geological Survey records, Delisle’s Dryden-area work and later technical notes document a long history of gold showings, old workings, visible-gold quartz veins and a non-compliant historical resource at Sakoose. The modern opportunity is to test whether those fragmented records form part of a larger, repeatable district system.^{M7,M8,M9,M10,M13}

The important point is that the historical material has value, but not as a current resource. It provides evidence of grade, fertility and structure; RHR still has to prove continuity, geometry and scale through modern drilling before any compliant resource value can be claimed.^{M7,M8,M9,M10,M13}

‍

‍

Seven priority targets were identified for the maiden campaign, with approximately 1,370 m of planned drilling. The wider exploration case is anchored by Sakoose and Maw because both have specific historical descriptions, structural settings and visible-gold quartz vein evidence, while Tabor has provided recent calibration data for the broader system. The 13 July 2026 field programme has now added ground-truthing across Sakoose, Maw and Church Lake, with 35 rock-chip samples submitted for gold and multi-element analysis and assay results expected during Q3 2026^M7-10,M13-14. 

‍

For context, the cited Ontario Geological Survey terminology distinguishes between an occurrence, a prospect and a mine: an occurrence has had less than 600 m of diamond drilling; a prospect has underground development or more than 600 m of diamond drilling plus significant surface work; and a mine is a former producer of any amount of the commodity.^M8

‍

Regional and property geology

Martello lies within the Wabigoon greenstone setting and is underlain by mafic volcanic, sedimentary and felsic intrusive rocks. The key exploration relevance is structural: gold-bearing quartz veins appear to be controlled by dike contacts, lithological contacts, shears and fold-related traps rather than by a single simple vein.^M7,M8

‍

Sakoose and Maw: the principal historical evidence

Delisle’s mapping provides the strongest description of Sakoose and Maw. At Sakoose, a felsic dike appears to control much of the gold-bearing shear zone, with quartz veins, pods and lenses developed around dike contacts, shaft areas and fold-related settings. Maw adds nearby repetition, with saddle-reef and oblique shear-hosted veins. The July 2026 field programme adds current validation: at Sakoose, the historically mined quartz vein was observed locally varying from approximately 15 cm to 2 m in thickness, with additional quartz veinlets and widespread hydrothermal alteration in quartz-feldspar porphyry and surrounding metabasalt.^M7,M8,M14

In effect he was suggesting a district-scale, multi-target approach that RHR is now initiating.

‍

‍

Maw matters because it shows the system may repeat away from the old Sakoose shafts. Saddle-reef geometry points to fold-hinge traps, while oblique shear-hosted veins add a second structural setting nearby. The July 2026 reconnaissance also recorded quartz veins and veinlets at Maw within gabbro and quartz-feldspar porphyry dykes, with several structural orientations mapped and one sample collected from a stockpile at the principal historical working.^M7,M8,M14

That makes Maw a useful miniature of the district thesis: the same broad mineralising system seen at Sakoose appears nearby in a different fold-controlled expression. Church Lake adds another field-validated target, with quartz veins, historical workings and multiple structural trends mapped during the July 2026 programme, although vegetation limited exposure in parts of the area.^{M7,M8,M9,M10,M13,M14}

‍

Production & historic resource

Ontario Geological Survey records summarise the documented output and a historical resource estimate:

‍

These figures are historical and are sourced from Ontario Geological Survey records; they are not reported under NI 43-101 or JORC and should not be treated as current mineral resources. They remain important because they substantiate the high-grade character of the system, including the approximately 14.8 g/t historical production grade and the reported 1988 intercept of approximately 10.3 g/t over 6.86 m.^M7,M8

‍

Modern interpretation and Tabor calibration drilling

The maiden Tabor programme should be read primarily as calibration drilling rather than as resource-definition drilling. Seven holes, TB-26-001 to TB-26-007, were completed for an aggregate 1,307 m, testing the Tabor system, validating historical concepts and helping define the parameters of the broader Martello model.^M9,M10,M13

The programme confirmed quartz–feldspar porphyry contact control on veining, intersected stacked quartz veins with visible gold in hole TB-26-002 and returned a best metallic-screen assay of 3.15 g/t Au over 0.70 m. In a coarse-gold setting, this is more useful as geological confirmation than as a standalone grade result.^M9,M10,M13

The key output from Tabor was therefore interpretive: it helped validate the structural model, improve the 3D target framework and sharpen the rationale for ranking Sakoose as the highest-priority target for the next phase of work.^M9,M10,M13

‍

‍

Grade context remains important, but it should be handled with discipline. Historic production at Sakoose, visible-gold quartz veins, grab samples, channel samples and isolated drill intercepts are evidence of a fertile high-grade system; they are not substitutes for modern drilling, compliant resource estimation or continuity testing. The July 2026 rock-chip samples are therefore best viewed as a potential near-term validation catalyst for a wider system: positive assays could strengthen target ranking and drill planning, but they would still need to be followed by drilling to test continuity and geometry.^{M7,M8,M9,M10,M13,M14}

In coarse-gold systems such as Sakoose, Maw and Tabor, conventional fire assays can under-report grade because a single coarse gold particle may or may not be captured in a small analytical charge. This is why metallic-screen fire assays are relevant over visible-gold intervals, and why historical high-grade samples should be read as indicators of fertility rather than estimates of average grade.^{M7,M8,M9,M10,M13}

‍

Why Sakoose ranks first

Sakoose ranks first because it combines four things that matter most at this stage: historic high grade, interpreted strike, structural repetition and a clear first drill test. The investment point is simple: RHR is not just re-visiting an old mine; it is testing whether the old workings sit within a broader corridor of repeated, drillable structures.^{M7,M8,M9,M10,M13,M14}

The current model links Sakoose to E–W and ENE–WSW corridors cut by NW–SE structures, with at least four interpreted E–W lineaments, several gold-in-soil coincidences and July 2026 field observations of additional quartz veinlets and hydrothermal alteration beyond the historically mined vein. That supports a multi-structure test rather than a single-vein restatement.^{M9,M10,M13,M14}

The deep magnetic feature beneath Sakoose is best treated as blue-sky upside, not evidence of depth continuity. Its value is sequencing: if shallow drilling supports continuity, the magnetic feature becomes a later, testable depth concept rather than a current valuation driver.^M9,M10,M13

‍

‍

The Wider Target Portfolio

The wider target portfolio gives Martello optionality beyond Sakoose. The priority targets share variations of the same structural controls, particularly E–W to ENE–WSW trends, cross-cutting structures and magnetic features that can be ranked and tested in sequence.^M9,M10,M13

The table below summarises the practical role of the key targets in the current exploration model.

‍

‍

Each target is an independent opportunity to test a related mineralising system, but the value of the portfolio lies in sequencing: Sakoose provides the highest-grade historical anchor, Maw tests nearby fold- and shear-hosted repetition, Tabor calibrates the model with recent drilling, and Church Lake now adds a ground-truthed target with quartz vein occurrences, historical workings and multiple structural trends. The remaining targets test whether the same structural architecture repeats across the broader claim package.^{M7,M8,M9,M10,M13,M14}

‍

Costs & Infrastructure

Martello’s infrastructure profile is part of the investment case, not a secondary detail. The project is road-accessible, close to Dryden and positioned in established forestry and mining service country, so RHR should be able to direct more of each exploration pound into drilling, sampling and target validation rather than camp construction, aviation support or remote logistics.^M2,M7

‍

‍

The practical implication is straightforward: road access, nearby services and target sequencing should lower all-in exploration cost relative to remote aviation-supported programmes, while allowing RHR to test Sakoose first and then move through Maw and the wider portfolio if results justify it. Exact cost per metre will still depend on contractors, season, hole design, assay scope and mobilisation requirements.^{M2,M7,M9,M10,M13}

‍

Permits

RHR has submitted an exploration permit application covering Sakoose and other priority targets within Martello.^{M9,M10,M13,CIP5} The application was circulated by the Ontario Ministry of Energy and Mines on 11 June 2026 and is progressing through the statutory consultation process,^CIP1,CIP2 linking the technical ranking exercise to the next physical work programme.

‍

‍

Outlook for Gold

The gold backdrop is supportive, but it should remain context rather than dominate the note. The strongest structural point is that official-sector demand remains material: central banks continue to treat gold as a reserve-diversification asset, Q1 2026 demand was supported by continued official-sector buying and reserve-management work still frames gold as a useful diversifier alongside foreign-exchange assets.^G1,G2,G7

Asia adds a second dimension. China’s official reserve accumulation and tightening of leveraged retail gold trading point to a market being pushed away from speculative paper access and toward more controlled, physical or non-leveraged channels, while Hong Kong’s new central clearing and settlement system is designed to deepen physical delivery, storage, price discovery and connectivity with the Mainland gold market.^G3,G4,G5

Two charts frame the reserve argument. Foreign central banks’ gold holdings have overtaken their US Treasury holdings as a share of reserves, signalling a symbolic shift toward hard assets, but this should not be read as a one-way rejection of Treasuries. Foreign private investors have simultaneously become more important buyers of US Treasuries, meaning official-sector diversification can coexist with private-sector demand for dollar debt when yields are attractive.^G10,G11

‍

The speculative layer is more fragile. Gold ETF flows show that investors can chase the move at the highs and then unwind quickly: June 2026 saw broad gold ETF outflows even though first-half flows remained positive overall. For RHR, that makes the gold backdrop useful but not decisive: it can improve appetite for high-grade junior exploration, but the re-rating still has to come from Martello-specific progress rather than from the gold tape alone.^G9

The investment implication is therefore simple: assays, permit progress, Sakoose drilling, continuity evidence and disciplined funding matter more than macro endorsement. A supportive gold market may make investors more willing to fund the sequence, but only drilling can move Martello from historic high-grade optionality toward a credible resource pathway.

‍

Valuations

Valuation is difficult because Martello is still pre-resource. There is no compliant NI 43-101 Mineral Resource Estimate, no mine plan and no basis for a formal DCF or NAV. The useful starting point is therefore simpler: what value is the market already assigning to Martello, what has RHR committed to acquire and advance it, and what evidence would justify moving that value higher?^{V1,V2,V3,V4,V5,V8,V9,V19,V22}

Following the 13 July 2026 field-programme update, RHR’s share price moved to approximately 1.4p and the market capitalisation increased to approximately £10.29m. The working allocation in this note remains deliberately simple: assign approximately £4.0m to Saint-Sophie and treat the residual c. £6.3m as the implied market value of Martello.^{V1,V6,V7,V8,V10,M14}

‍

‍

‍

Resource-stage valuation framework

Because Martello has no current NI 43-101 resource, the valuation framework should be read as a staged progression rather than a resource claim: historical evidence supports option value; drilling can support an inferred-resource framework; only later technical studies can support NAV-style valuation.^{M7,M8,V9,V13,V14,V15,V19,PC12,PC13,PC14,PC20,PC21}

‍

1976 Sakoose pocket: base historical reference

The 1976 Sakoose estimate is best treated as a historical pocket reference, not a district resource. The reported figure was 50,000 tons at 12.7 g/t Au. If interpreted as short tons, that equates to approximately 45,359 tonnes, 576,059 grams of contained gold and approximately 18,520 oz Au. If interpreted as metric tonnes, the same calculation produces approximately 20,416 oz Au. The appropriate working range is therefore c. 18,500–20,400 historical, non-compliant ounces.^M7,M8,V9

Calculation step

Valuation matrix note: the £19–£35/oz range is intended for early-to-improving Inferred-resource scenarios and is a sterling approximation of a US$25–45/oz heuristic, converted at an illustrative GBP/USD rate of 1.30. The lower £10–£19/oz range reflects a wider early-resource haircut for lower confidence, wider drilling, narrow-vein variability and the absence of engineering studies. The £35–£65/oz district range reflects a premium for larger compliant scale, grade, tier-one jurisdiction, infrastructure and evidence of repeated mineralised structures. The blue-sky advanced-development reference converts a US$80–150/oz rule-of-thumb range at the same illustrative GBP/USD rate and should only be considered if

Martello moves beyond a simple Inferred-resource case into a 1Moz+ resource with materially stronger engineering, metallurgical and economic evidence. These ranges are market heuristics, not formal standards, and should be cross-checked against live peers and transaction evidence.^{V19,V22,PC18,PC19}

‍

District valuation bridge

District valuation should be read as a ladder. At the current stage, Martello is valued on cost, jurisdiction, infrastructure, targeting and option value. If drilling supports a compliant resource, EV/resource ounce becomes relevant. NAV or DCF only becomes appropriate once there is enough technical work to support mine design, recoveries, capex and operating assumptions.^{PC18,PC19,PC20,PC21,PC22,V22}

‍

Drilling budget and dilution logic

The company has not disclosed the size of the next post-Tabor campaign, so the drilling budget in this note is an analyst scenario. The logic is simple: RHR does not need reserve-style drilling to start, but it does need enough modern pierce points to show whether Sakoose has geological and grade continuity across the interpreted corridor.^{M9,M10,M13,PC12,PC20,PC21}

Using a 1.4 km corridor and an initial 300 m depth test, a simplified grid implies roughly 84 pierce points. At an average inclined hole length of about 110 m, that equates to approximately 9,240 m of drilling, consistent with the 7,000–10,000 m expanded inferred-grid scenario used below. The exact metreage would depend on orientation, spacing, vein continuity, use of historical data and whether multiple subparallel structures can be tested from the same collars.^{M9,M10,M13,PC12,PC20,PC21}

‍

‍

GBP equivalents use an illustrative GBP/CAD rate of 1.846, consistent with the exchange rate already used in this note for the Bartlett and Esler claim conversion. The step-up route is the most realistic funding pathway: RHR could complete an initial Sakoose test first, then raise or deploy incremental capital only if early results justify expanding toward a resource-style grid. Actual sterling funding needs will vary with exchange rates, contractor terms and programme scope.^V23

‍

Dryden Gold’s disclosed all-in drilling cost reference of approximately CA$250/m provides a useful local benchmark for road-accessed northwestern Ontario drilling, but RHR’s actual cost per metre will depend on contractor availability, hole depth, assay scope, core handling, season and mobilisation. The absence of helicopter mobilisation should help, but it does not remove the need for a meaningful capital raise if RHR intends to move Sakoose toward a resource-style drill grid.^PC16

‍

Equity dilution at a 1.4p financing price

For dilution purposes, this note uses the 735.248m post-Bartlett share count as the starting fully paid/basic position. This reflects the 718.264m ordinary shares reported at the 31 March 2026 half year plus the 16.984m Bartlett consideration shares, which are treated here as already funded/economically committed even if the timing of formal issue/admission differs. Following the 13 July 2026 field-programme update, the share price moved to approximately 1.4p and the market capitalisation to approximately £10.29m; this section therefore uses 1.4p as the current reference financing price for dilution sensitivity. The April 2026 option grant RNS stated that total options outstanding were 63.26m; on the 735.248m starting base, simple fully diluted shares are therefore approximately 798.5m before any new financing, excluding any undisclosed warrants or later option grants not identified in the public sources reviewed.^{V1,V20,V21,SS1,SS2,SS3,M14}

‍

‍

The final row combines the high end of the initial Sakoose test and the high end of the expanded Inferred-grid campaign for a simplified full resource-style funding case. It is deliberately conservative because it excludes issue costs, possible warrant sweeteners, working-capital buffers and any proceeds from option exercise.

‍

Peer Comps

‍

Source: note PC1

The peer comparison should do one job: explain the evidence gap. RHR trades within the range of its peers shown above^PC1 but well below better-funded Ontario gold explorers because Martello is still pre-resource and Sakoose has not yet been systematically drilled.^PC1,M14 For instance, Dryden Gold commands a materially higher valuation because it has advanced a Wabigoon district story with repeated mineralised structures,^PC7 a large 2026 drill programme,^PC8 and strategic backing from Centerra Gold^PC15 and Alamos Gold.^PC15 The upside case is that, in our view, Martello has the ingredients peers are rewarded for — high-grade history, consolidated ground, infrastructure and a district thesis — but it still needs drill confirmation before the market could value it like a de-risked Ontario exploration platform, such as GFG Resources^PC3 at the active regional-exploration stage, Wallbridge^PC4,PC9 at the resource-backed discovery stage or New Found Gold^{PC5,PC10,PC11} at the more advanced discovery-platform and consolidation stage.

‍

Table FX note: GBP equivalents use the GBP/CAD rate of 1.846 applied elsewhere in this note.

‍

Dryden Gold: the closest Wabigoon analogue

Dryden Gold is the most useful analogue because it shows how a Wabigoon gold story can re-rate once the evidence base becomes specific. Its higher market value provides the valuation read-across,^PC2 while the technical case is supported by reported repeated mineralised structures at Gold Rock,^PC7 a 45,000 m 2026 drill campaign,^PC8 and strategic investment from Centerra Gold and Alamos Gold.^PC15 Its disclosed CA$250/m drilling-cost reference is also useful for benchmarking road-accessed northwestern Ontario exploration costs.^PC16 RHR is earlier and riskier, but that is precisely why the upside remains more asymmetric if Sakoose drilling begins to close the evidence gap.

‍

Deals and multiples: why district-scale gold assets are being consolidated

Recent gold-sector M&A is useful only as strategic context, not as evidence that Martello is an immediate takeover target. The relevant read-through is narrower: Ontario’s policy backdrop remains supportive for mine development and capital investment,^D1 EV/resource-ounce and NAV-style metrics are useful only once a project has sufficient resource or study definition,^D2,D3 and strategic investors can validate earlier district stories before formal development if the geology and funding case are credible.^PC15 For RHR, the nearer-term opportunity is therefore more likely strategic funding, a JV, farm-in or industry validation if Sakoose drilling works.

‍

Recent activity and deal logic

The important discipline is comparability. Greenstone is useful as an Ontario consolidation example because Equinox bought out Orion’s 40% interest and later consolidated 100% ownership of the mine,^D4,D5,D6 while Valentine shows the premium attached to a more advanced development platform with reserves, resources and a near-term production plan.^D16,D17,D18 Madsen is a redevelopment and infrastructure case, not an early exploration benchmark,^D13,D14,D15 and Hemi is a large-scale development transaction with a resource, reserve and A$5bn control premium context.^D7,D8,D19 These examples show where the valuation ladder can lead if drilling, resource definition, infrastructure and financing evidence are progressively added; they do not set a current transaction multiple for Martello.

Explorer-level transactions also matter because district consolidation can happen before production or even before a mature development study: Kenorland’s Central Uchi / Golden Sidewalk acquisition shows how juniors can assemble larger Ontario greenstone positions around a coherent belt-scale thesis.^D11 AIM funding precedents are relevant too: targeted raises such as First Class Metals’ £1m Ontario placing show that small-cap explorers can raise discrete amounts for named exploration programmes, which is the type of staged financing RHR is likely to require if Sakoose results justify the next drill phase.^D12

That leaves a simpler conclusion: RHR should be valued today on evidence and sequencing, not takeover speculation. Peer and deal evidence matter because they define the pathway — better drilling evidence, stronger funding quality, strategic validation and eventually compliant resources — not because they set a current transaction multiple for Martello.

‍

Timeframe of development

RHR enters the second half of 2026 with a clear near-term catalyst sequence centred on Sakoose, now reinforced by the completion of the July 2026 field reconnaissance and rock-sampling programme across Sakoose, Maw and Church Lake. Near-term value creation depends on assay results, permit progress, drilling and interpretation; full mine development, if ever achieved, would be a multi-year process involving resource definition, economic studies, permitting, financing and construction.^{M3,M14,T1,T2,T3,T4}

‍

‍

Generic development timing heuristic

Exploration companies often move quickly between catalysts, but the full mining lifecycle is slow. A useful rule of thumb is that exploration and discovery can take several years, resource definition and economic studies add further years, and mine permitting, financing and construction are highly project-specific. RHR’s immediate investment case is therefore not mine production; it is whether Sakoose can move from historical and geophysical evidence toward drill-confirmed continuity.^{T1,T2,T3,T4,PC12,PC13}

‍

‍

Catalyst watch: the most important near-term events are assay results from the July 2026 field samples, permit grant, rig mobilisation, first Sakoose collars, drill assay results and the decision whether to step up into a broader inferred-grid programme. The key value test is not production timing; it is whether RHR can demonstrate that Sakoose is a connected, drill-confirmed high-grade structure rather than a historical pocket.^{M3,M9,M10,M13,M14,PC12,PC13}

Each milestone is discrete and value-relevant, but capital availability will determine pace. The road-accessed setting should help RHR move more efficiently than a remote fly-in explorer, yet any transition from initial Sakoose testing to a resource-style grid will almost certainly require additional equity funding. That is not unusual for a pre-revenue explorer; the key question is whether early results justify the dilution required for the next stage.

‍

Shareholder Structure

As at the 31 March 2026 half year, RHR reported approximately 718m ordinary shares in issue. This is the appropriate baseline share count for the valuation and dilution analysis in this note, with any subsequent financing or option exercise treated as incremental dilution rather than part of the starting equity base.

Subsequent disclosed issuance means the 31 March 2026 half-year figure should be treated as the analytical baseline rather than the latest legal share count. The Bartlett acquisition added 16,983,827 consideration shares at 1.75p per share, taking disclosed issued share capital to 735,248,168 ordinary shares following admission. Those Bartlett consideration shares are subject to lock-in release in four equal instalments on 15 October 2026, 15 April 2027, 15 June 2027 and 15 October 2027.^SS1,SS2

Options and warrants are the main disclosed equity-linked overhangs. On 27 April 2026, RHR granted 31.0m director options exercisable at 2p and expiring on 31 March 2028. Following that grant, total options outstanding were 63,262,071, representing 8.6% of the then issued share capital. The company also discloses 148.45m warrants outstanding in the capital structure used in this note.

On the disclosed 735.25m post-Bartlett share count, simple fully diluted shares would therefore be approximately 946.96m before any new financing, warrant issue, option exercise proceeds or later option grants.^SS3

The principal known deal consideration still to come is cash rather than shares: the original Martello term sheet provides for £50,000 payable on or before 31 October 2026, £50,000 payable on or before 31 March 2027, and further deferred consideration of up to £300,000 in cash subject to completion of drilling and RHR obtaining a mineral resource estimate on Martello. No additional share issuance for that deferred Martello consideration has been identified in the cited public terms, although future equity financing may still be required to fund drilling and working capital.^SS4,SS5

‍

Conclusion & Opportunity Summary

Richmond Hill Resources offers a concentrated, early-stage gold exploration opportunity built around a simple strategic question: can the company convert Martello’s historic high-grade evidence into a modern, drill-confirmed district-scale gold system? The answer is not yet proven, but the starting point is materially stronger than a blind grassroots exploration story. Sakoose has recorded high-grade historic production, Maw and Tabor support repetition of similar structural controls, and modern drone magnetics, 3D inversion and target ranking have created a more disciplined drill sequence across the wider claim package.

The opportunity is therefore asymmetric but conditional. 

RHR is positioned before the main Sakoose drilling decision point, where a relatively modest initial programme could materially change the probability assigned to the Martello thesis. If drilling confirms continuity, grade and repeated structures, the project could move from historic-optionality value toward a resource-definition pathway. 

That is the point on the Lassonde Curve where micro-cap explorers can re-rate quickly, especially when the asset is in a tier-one jurisdiction, is road-accessible, and sits in a gold market where senior producers and larger juniors are actively looking for credible pipeline assets.

‍

The valuation work in this note frames the opportunity as a staged project-valuation exercise rather than a single forecast. Following the 13 July 2026 field-programme update^M14, RHR traded around 1.4p with a market capitalisation of approximately £10.29m, implying Martello at approximately £6.3m after allocating c. £4.0m to Saint-Sophie (as we showed in the Martello costs basis part of the valuation section), compared with a committed Martello cost basis of approximately £1.8737m before any contingent resource-linked consideration becomes due . That updated Martello value now rewards consolidation, modern targeting, July field validation and near-term assay/drilling optionality, but it still sits below the illustrative valuation waypoints generated in the resource-stage analysis.^M14.

The peer and transaction analysis reinforces that this is an evidence-gap story rather than a simple mispricing. Our opinion is that RHR currently trades below better-funded Ontario and Wabigoon exploration peers because Martello has not yet produced systematic Sakoose drill confirmation or a compliant resource. However, those same peers and recent district-scale transactions show why the prize can expand quickly if drilling converts historic high-grade evidence into a credible resource pathway. The deals section is not used here to argue that RHR is an immediate M&A target; it shows that once scale, continuity and jurisdictional quality are demonstrated, strategic capital tends to follow assets with consolidated ground, infrastructure and district optionality.

‍

The investor question is therefore whether each incremental funding stage can buy enough geological confidence to justify the dilution. 

Using the 735.248m post-Bartlett fully paid/basic share count as the dilution base, an initial Sakoose test funded at the updated 1.4p reference price implies approximately 3.8%–5.9% dilution. That stage does not need to prove a resource; it needs to confirm that Sakoose is a drillable, mineralised structure with continuity potential. If it merely confirms the current thesis without materially extending it, the likely outcome is preservation of the current c. £6.3m Martello valuation rather than a major re-rating.

The next step-up is where the risk/reward becomes more compelling. An expanded inferred-grid campaign at the updated 1.4p reference price would imply approximately 8.5%–13.7% dilution, while the full modelled resource-style campaign of £2.28m would imply approximately 18.1% dilution before costs, warrants or working-capital buffers.

Against that dilution, the valuation matrix shows that a 500,000 oz compliant scale case could imply a Martello asset value of approximately £9.5m–£17.5m, or around 1.5x–2.8x the current implied Martello value before dilution and funding effects. That is the first genuinely value-enhancing outcome because the project valuation uplift can more than offset the modelled equity dilution.

The district case is the blue-sky but still disciplined endpoint for the current analysis. If Martello ultimately supported a 1Moz compliant district case, the valuation framework points to approximately £35m–£65m of illustrative Martello asset value, or around 5.6x–10.3x the current implied Martello value before dilution and funding effects. A more advanced 1Moz-plus development-style reference could be materially higher again, but that would require not only ounces, but stronger engineering, metallurgical and economic evidence.

These are not resource forecasts; they are the numeric milestones that show why the dilution risk is worth taking if each drilling stage materially increases the probability of reaching the next valuation band.

The phase-driven financing strategy is important because success should change the price at which future capital can be raised. In the ideal path, RHR does not finance the full resource-style campaign at today’s share price. It funds the first Sakoose test, uses results to increase geological probability, then raises the next tranche against a higher market valuation if the work supports the model. That creates a self-feeding mechanism: stronger results may increase project value, a higher project value could contribute to a stronger share price, and a stronger share price reduces the number of new shares needed for the next drill phase.

The conservative case is equally important. If confirmation takes longer, if results are technically useful but not marketable, or if the gold-equity tape weakens, later financing may still have to be done at or near the current 1.4p reference price. In that case, the dilution table should be treated as the right base case and the investment case becomes slower: investors are paying for methodical technical de-risking rather than immediate discovery-style re-rating.

‍

The conclusion remains constructive, but only because the potential valuation uplift from Martello is large enough to justify dilution if drilling genuinely moves the project from historic-optionality value toward scale, continuity and eventually resource-style credibility.

‍

Final Price Target / Watchlist

The appropriate near-term target framework is milestone-based rather than a single fixed price target: current Martello implied value is c. £6.3m; First up will be the drilling programme that is designed to define the parameters of the district and potentially confirm the existence of the resources in the base case thesis; a credible 500,000 oz pathway could move the project toward the £9.5m–£17.5m scale-case range; and a larger district outcome would require evidence that Martello can evolve toward the £35m–£65m 1Moz-style valuation band.

Saint-Sophie remains a separate copper-gold project carried at c. £4.0m in this note. If Martello execution improves, investors may also begin to assign more value to Saint-Sophie and to management’s ability to acquire, fund and advance value-accretive projects.

‍

On this basis, an 18-month target framework around 12p is defensible if early Sakoose progress confirms the district thesis and moves Martello toward a credible 500,000 oz-plus pathway. Further upside would require stronger evidence of scale, continuity and a credible route toward resource-style valuation; downside would follow if drilling were delayed, inconclusive or repeatedly financed at current levels.

The share-price path is therefore probabilistic: assay results, permit progress, drilling, financing quality and any strategic interest each act as potential positive/negative gateways to the next valuation band.

What to Watch for a Curve Uptick

Watch five milestones to judge whether RHR is moving up the curve from historic-opportunity value toward resource-definition value:

1. Permit and mobilisation: permit grant, funding and rig mobilisation would move Sakoose from ranked target to physical validation.
2. Initial drill results: the key test is whether drilling confirms mineralised structures, continuity and geometry around Sakoose, not just isolated high-grade hits.
3. Step-up decision: a move toward an inferred-grid programme would signal that early drilling has improved the probability of a 500,000 oz-style pathway.
4. Financing quality: a higher-priced, staged raise after positive results would show that dilution is being matched by improved project probability.
5. Strategic interest: institutional, JV or industry interest would validate the district thesis and reduce the burden of RHR funding every phase alone.

Risks & Sensitivities

Risks should be read as the discipline check against the opportunity case. The core sensitivity is whether each phase of work increases geological confidence quickly enough to justify the dilution required for the next stage. If drilling confirms fertility but not continuity or scale, Martello may hold its current implied value but struggle to earn a higher premium; if drilling confirms repeated mineralised structures and a credible scale pathway, the project-value uplift can outweigh dilution.

• Exploration and continuity risk: historic production, visible gold and legacy intercepts confirm fertility, but only modern drilling, QA/QC and interpretation can establish continuity, geometry and grade.
• Dilution and funding risk: additional equity is required for the modelled drill stages; dilution is acceptable only if each raise materially increases the probability of a higher valuation band.
• Timing and market risk: permit timing, rig availability, assay turnaround and gold-equity sentiment can delay news flow and force later financing at or near the current 1.4p reference price.
• Interpretation risk: the district thesis depends on Sakoose, Maw, Tabor and other targets forming part of a connected structural system; geophysics improves targeting but does not prove continuity.
• Portfolio premium risk: Saint-Sophie should remain valued separately unless Martello execution improves confidence in management’s broader acquisition, funding and technical strategy.
