Black Bear Minerals (ASX: BKB) — Independence Project Gold Resource Grows to 2.2 Million Ounces Including 1.0Moz High-Grade Skarn at 6.3 g/t Au in Nevada
On 13 May 2026, Black Bear Minerals Limited (ASX: BKB) announced an updated Mineral Resource Estimate for its Independence Project in Lander County, Nevada, with the combined resource increasing to 2.2 million ounces of gold equivalent. The resource comprises two distinct deposit types: a high-grade Inferred skarn resource of 5.0Mt at 6.29 g/t Au for 1,002,500 oz gold, and an epithermal resource of 89.9Mt at 0.42 g/t AuEq for 1,217,400 oz AuEq (1,100,500 oz Au and 19,970,400 oz Ag) split between Indicated (26.6Mt at 0.44 g/t AuEq for 376,300 oz) and Inferred (63.3Mt at 0.41 g/t AuEq for 841,100 oz). The updated MRE represents an increase of 815,900 oz since the 2025 Maiden MRE, achieved at a mineral resource growth cost of A$4.71 per ounce. Both the epithermal and skarn mineral domains remain open along strike and at depth.

Independence Project — Two Deposit Types Within a Single System
The Independence Project hosts two vertically stacked mineralisation types related to the same Eocene-age intrusive event:
Epithermal mineralisation (from surface): Gold-silver mineralisation hosted in chert and argillite beds of the Upper Pumpernickel Formation, characterised as a high-level epithermal system developed as a leakage halo above the skarn. The epithermal resource spans approximately 1.5 km of strike with 11 modelled domains in a parallel stacking configuration. The oxide portion of the epithermal resource is amenable to heap leach extraction — the same processing method used at the adjacent Nevada Gold Mines Phoenix Mine Complex and the nearby SSR-operated Marigold Complex.
Skarn mineralisation (at depth): High-grade gold hosted in calcareous conglomerate and sandstone of the Battle Formation beneath the Golconda Thrust. The skarn resource at 6.29 g/t Au has demonstrated non-refractory gold with recoveries up to 95.9% through gravity recovery followed by carbon-in-leach (CIL) processing, with low reagent consumption and very low deleterious elements.
Resource Growth — 815,900 Ounces Added at A$4.71 Per Ounce
The 2026 MRE represents a combined increase of 815,900 oz AuEq since the March 2025 Maiden MRE. The epithermal portion grew from 419,600 oz (2025, pit-constrained) to 1,217,400 oz AuEq (2026, unconstrained) — an increase of approximately 190%. This growth reflects new mineralisation outlined from 2024–2025 extension drilling, the removal of the outdated pit shell (originally optimised at US$1,600/oz Au), re-classification of oxidation states, and updated density measurements.
The skarn resource has not been drilled further since the maiden estimate, but new density measurements from historic core and compilation of additional raw data led to a revised estimation at 5.0Mt @ 6.29 g/t Au for 1,002,500 oz.
Extension Potential — Open Along Strike and at Depth
The company identifies several areas of growth potential:
The Rebel Trend (eastern portion) is defined over 280m of strike with mineralisation open to the north, south, and down dip, with approximately 1 km of untested strike remaining. The southern half of the epithermal resource has only been historically drilled to shallow set depths (~100m) targeting uppermost lodes, with potential for stacked lodes at depth as demonstrated in the northern half. The skarn resource remains open northward, with historic hole WI-002 intersecting similar skarn mineralisation 580 metres outside the current resource area. The Lower Pumpernickel Formation between the epithermal and skarn resources has limited sampling but has returned intercepts including 21.7m at 1.0 g/t Au (WI-002) and 6.1m at 2.2 g/t Au (IND-07).
Market Context
BKB closed at $0.780 on the announcement day, up +18.2% from a previous close of $0.660, with an intraday high of $0.815. The 52-week range spans $0.470 to $1.110. The Independence Project is located in the Battle Mountain Mining District of Nevada, adjacent to Nevada Gold Mines' Phoenix Operation, within a district that has produced more than 40 million ounces of gold.
Risks & Considerations
Classification: The skarn resource (1.0Moz, 45% of the total) is entirely Inferred, based on widely spaced historic diamond drilling. The epithermal resource is split between Indicated (376,300 oz, 31%) and Inferred (841,100 oz, 69%). Inferred Resources carry a lower level of geological confidence.
No economic study: No scoping, pre-feasibility, or feasibility study has been completed for the Independence Project. The 2022 NI 43-101 PEA is considered outdated. Mineral Resources that are not Ore Reserves do not have demonstrated economic viability.
Pit shell removed: The 2025 Maiden MRE was constrained by a pit shell optimised at US$1,600/oz Au. The 2026 epithermal estimate is reported without pit constraint. This means the reported resource includes material that may not be economically extractable under a pit-constrained scenario at current or lower gold prices.
Metallurgical testwork gaps: Epithermal metallurgical testwork has focused on heap leach for oxide material only. Transitional and sulphide material (which comprise a significant portion of the Inferred epithermal resource) have not been optimally tested. The assumed recoveries of 50% (transitional) and 22% (sulphide) are preliminary and could change with further testwork.
Silver recovery: Silver recovery across all oxidation states is assumed at only 27%, contributing to a relatively low silver contribution to the AuEq calculation. Higher silver recovery from future testwork could increase AuEq grades, but this has not been demonstrated.
Historic data reliance: A substantial portion of the drill database is from pre-2007 campaigns with limited documented QAQC. While comparison analysis shows reasonable correlation with newer data, some historic field duplicates and CRMs have been flagged with inconsistencies.
Tenement boundary assumption: The block model assumes pit walls can breach current tenement boundaries through negotiations with neighbouring lease holders. This is not confirmed.

- The announcement — Independence Project MRE Increased to 2.2Moz — was the primary catalyst for the price movement.
- The updated MRE comprises 1.0Moz Au in high-grade Inferred skarn (5.0Mt @ 6.29 g/t Au) and 1.2Moz AuEq in epithermal resources (89.9Mt @ 0.42 g/t AuEq, split Indicated/Inferred), representing 815,900 oz growth since the March 2025 Maiden MRE at A$4.71/oz resource growth cost.
- The epithermal resource grew ~190% following extension drilling, removal of the outdated pit shell, and updated oxidation/density modelling. The skarn resource was re-estimated using new density data but has not been drilled further.
- Both deposit types remain open along strike and at depth, with 1 km of untested Rebel Trend strike, a 580m gap to the north of the skarn, and stacked lode potential beneath the southern epithermal resource.
- No economic study has been completed. Metallurgical testwork for transitional and sulphide epithermal material is needed. The skarn is entirely Inferred from wide-spaced historic drilling.
Summary
Black Bear Minerals announced an updated Mineral Resource Estimate for its Independence Project in Nevada's Battle Mountain Mining District, with the combined resource increasing to 2.2 million ounces AuEq — comprising a 1.0Moz high-grade Inferred skarn at 6.29 g/t Au and a 1.2Moz AuEq epithermal resource (Indicated + Inferred) at 0.42 g/t AuEq hosted from surface. The update represents 815,900 oz of growth since the March 2025 Maiden MRE at a resource growth cost of A$4.71 per ounce. The announcement coincided with an +18.2% move to $0.780. The epithermal system spans 1.5 km of strike and is amenable to heap leach processing (oxide material), while the skarn has demonstrated gold recoveries up to 95.9% through gravity and CIL testwork. Both mineral domains remain open along strike and at depth, with multiple areas identified for further drilling. No economic study has been completed, and metallurgical testwork for transitional and sulphide epithermal material is needed to fully characterise the resource.
