Sierra Nevada Gold (ASX: SNX) is pleased to announce plans to follow up drill hole BHD006 which returned up to 1270 g/t silver at Endowment Mine, part of its Blackhawk Epithermal project in Nevada, USA.
Highlights
- Sierra Nevada to review potential for a large, high-grade epithermal silver-dominated vein system.
- Previously drilled core hole BHD006 returned 5m at 479 g/t Ag within a larger mineralised zone of 12m at 219 g/t Ag from 250m beneath the Endowment mine at its Blackhawk Epithermal Project in Nevada, USA.1
- This high-grade intercept is situated 150m vertically below the deepest portion of the historic mine and includes higher grade intersections of:
- 0.5m at 1270g/t Ag from 256.5m
- 1m at 823g/t Ag from 257m
- 1m at 654g/t Ag from 258m
- These silver intercepts are associated with very high-grade lead-zinc-gold (see table 1), demonstrating the potential for extremely high value ore.
- Potential for a company-making silver discovery at Blackhawk, where SNX has identified 22.5-line kilometres of high-grade silver-gold-lead-zinc veins.1
- Two shallow oxide resources (historic, non-JORC) estimated at Silver Gulch and Morning Star.1
- SNX has recently defined several high priority drill targets, and a multi-hole drill program is permitted.
SNX Executive Chairman Peter Moore said“These results which returned up to 1270 g/t silver from Blackhawk are very promising, coming from a vast and extensive vein network. We’ve identified 22.5-line kilometres of veins at Blackhawk, but this known mineralisation has sat largely untouched since mining ceased in the area in the 1920s. We have two shallow oxide resources which have not been defined to a JORC-compliant level but this provides us the opportunity to deliver value from an existing project with further drilling and mineral resource definition. Our 20-hole drill program is permitted and ready to drill, providing us with the opportunity to use modern exploration techniques to potential to return further high-grade results and shape this as a company-making discovery for Sierra Nevada.”
SNX has previously identified a large and high-grade intermediate sulphidation epithermal Ag-Au-Pb-Zn vein system, likely related to a large porphyry system located immediately to the south. Partially coincident with the porphyry system, the Blackhawk epithermal project vein system covers about 5km2 and is open under cover to the north and northeast, with 22.5-line km of veins identified to date (see figure 1).1

Previous drilling by SNX beneath the Endowment mine at Blackhawk returned 12m at 219 g/t Ag from 250m including 5m at 479 g/t Ag from 256m. This drill intercept is 150m vertically below the deepest portion of the mine and includes higher grade intersections of:
- 0.5m at 1270 g/t Ag from 256.5m (21.5% Pb + Zn)
- 1m at 823g/t Ag from 257m (30.1% Pb + Zn)
- 1m at 654 g/t Ag from 258m (+50% Pb+ Zn)
As shown in Table 1, the intersection described above comes with considerable polymetallic credits. The complete mineralised intersection of 12m at 219g/t Ag also contains 3.05% Pb and 8.54% Zn across the interval, significantly increasing the potential value of mineralisation within the vein/structures.

Piche Resources
Investor Insight
With high-quality, drill-ready assets, with world-class discovery potential, Piche Resources is a compelling business case for investors looking to leverage a bull market for uranium and gold.
Overview
Piche Resources (ASX:PR2) is focused on discovering significant uranium and gold deposits in Australia and Argentina. The company boasts a portfolio of high-quality, drill-ready assets with world-class discovery potential, presenting a compelling opportunity for investors aiming to capitalize on the bullish markets for uranium and gold.
Piche Resources’ portfolio includes the Ashburton uranium project in Western Australia’s prolific Pilbara region; the Sierra Cuadrada uranium project in the San Jorge Basin in Argentina; and the Cerro Chacon gold project which shares geological similarities with the Cerro Negro mine in Argentina. Exploration work at these assets indicate their potential to become world-class projects.
Piche has an internationally recognized board focused on creating long-term shareholder value, and an in-country technical team in Argentina with a proven track record of taking projects from discovery through to development.
Company Highlights
- The company’s Australian asset is the Ashburton uranium project, which has been drilled previously and recorded high-grade uranium intersections over significant widths.
- In Argentina, the company’s Sierra Cuadrada uranium project in the San Jorge Basin has a significant history of high-grade, near-surface uranium mining operations.
- Drilling at one of the prospects at Sierra Cuadrada has shown visible uranium in numerous holes. Multiple other prospects are drill-ready and have the potential to host tier 1 uranium deposits.
- Exposure to gold with high-quality precious metal projects in Argentina that boast surface outcrop samples with gold grade up to 13 g/t gold.
- Internationally renowned board and management team with extensive uranium and gold exploration and development experience.
Key Projects
Uranium: Ashburton Project, Australia
Project Highlights
- Location: Pilbara region, Western Australia, approximately 1,150 km north of Perth.
- Project Area: Comprises three exploration licenses covering a 122 sq km land package.
- Historical Exploration: Previous drilling by Pancontinental (62 holes) identified 71 intercepts with grades exceeding 500 ppm U₃O₈, averaging approximately 1.1 lbs of U₃O₈ per tonne. Notable high-grade drilling results include:
- 10.5 m at 4,380 ppm U₃O₈ (Hole AR1004)
- 9 m at 3,490 ppm U₃O₈ (Hole AR1009)
- Recent Development: In 2024, Piche completed a combined reverse circulation and diamond drilling program totaling 3,082.8 meters. The results exceeded expectations, validating previous findings. A follow-up drilling program is planned for mid-2025, targeting both Angelo A & B prospects and other areas within the tenement portfolio.
Uranium: Sierra Cuadrada, Argentina
The Sierra Cuadrada project is located in the San Jorge Basin and spans 1,300 sq km, 200 km north of Comodoro Rivadavia. The project is flat-lying, with visible uranium assays of >3,000 U3O8 or 6.6 lbs per tonne. The mineralization occurs at varying stratigraphic layers and remains open at depth. There is potential for numerous continuous zones up to 30 km wide and 40 km long. Mineralization is open along strike NW and SW and downdip. Further work will include delineating the deposit with shallow drilling and trenching that Pinche boasts can be done at very low cost.
Project Highlights:
- Location: San Jorge Basin, approximately 200 km north of Comodoro Rivadavia.
- Project Area: Spans 1,300 sq km of flat-lying terrain.
- Mineralization: Visible uranium assays exceeding 3,000 ppm U₃O₈ (6.6 lbs per tonne) have been observed. Mineralization occurs at various stratigraphic layers and remains open at depth, with potential for continuous zones up to 30 km wide and 40 km long.
- Historical Context: The Argentine National Atomic Energy Commission conducted extensive uranium exploration from the mid-1950s, identifying thousands of anomalies and developing eight mining operations. In the Chubut province, radiometric and EM surveys have highlighted two large Cretaceous paleochannels in the San Jorge Basin, extending over 200 km N-S and 30 to 60 km E-W. Notable high-grade deposits in the area include Cerro Condor and Los Adobes, both past-producing operations with grades of 6,000 ppm U₃O₈ and 1,400 ppm U₃O₈ found in outcrop, respectively.
- Recent Developments: Auger drilling in 2024 conducted at Sierra Cuadrada highlights extensive areas of near surface uranium mineralization. Assay results have been received for the shallow reconnaissance holes including 6 samples >1000ppm U₃O₈ (to maximum 2,650 ppm U₃O₈) and 2 samples >500ppm U₃O₈ (to maximum 900 ppm U₃O₈)
Gold: Cerro Chacon, Argentina
The Cerro Chacon gold project is located 10 km south of Paso de Indios, in the Chubut Province of Argentina. The land tenement spans 365 sq km of prospective precious metals occurrences. Structural mapping and geochemical sampling at the Chacon Grid identified mineralized systems consistent with surface signatures at the Cerro Negro Mine that boasts a contained metal inventory of 5.8 Moz of gold and 50 Moz of silver.
Project Highlights
