North Peak Resources Ltd. [TSXV: NPR; OTCQB: NPRLF] reported results from follow-up sampling within the Dean Cave complex at their Prospect Mountain (PM) property in Eureka, Nevada.
Following the company’s press release on May 27, 2025 where the company reported high-grade oxide mineralization in the Dean Cave area grading up to 46.5 g/t (1.36 oz/t) Au, 569 g/t (16.6 oz/t) Ag, further channel sampling was undertaken in the East Cave area on the 650′ level, some 46 metres (150ft) below the previously announced samples, and encountered multiple narrow high grade gossanous zones within a zone of heavily altered dolomite, including 180 g/t (5.8 oz/t) Au, 998 g/t (32 oz/t) Ag, 7.8% Pb, 1.05% Zn over 0.1m; 66 g/t Au, 371 g/t Ag, 2.85% Pb, 3.74% Zn over 0.16 m; 49.5 g/t Au, 402 g/t Ag, >20% Pb, 0.64% Zn over 0.09m and 27.3 g/t Au, 132 g/t Ag, 1.9% Pb, 2.9% Zn over 0.1m.
Only the gossanous zones were sampled in this sampling pass, given the high-grade nature of these zones the rest of the altered dolomite will be sampled to give better indications of potential historical grades from these old stope areas. The mineralization here appears strongly structurally controlled by the intersection of two fault systems, giving a plunge direction to explore for further mineralization along. This cave can be directly accessed by the Silver Connor portal from the west side of the mountain.
“These further high-grade results continue to demonstrate the strength and potential of this property. Our geology team has been utilizing Prospect Mountain’s extensive and accessible underground workings to build a greater understanding of the complex structural controls to mineralization,” commented Rupert Williams, CEO. “We expect our summer 2025 drill program to commence in September, with a plan to target several different structural control systems and will consider targeting this area with an additional RC drillhole from surface.”
“The company’s understanding of the complex structural controls to mineralization is rapidly advancing, increasing the likelihood of effectively targeting new zones of mineralization as has successfully been done elsewhere in the Eureka camp,” added David Pym, Lead Geologist. “These samples reinforce our exploration strategy of looking at the Property from three perspective target areas: the near surface oxide, underground oxide and the underground sulphide.”
The Dean Cave complex was one of the last areas to be mined in the historic Diamond mine, with sporadic activity continuing into the 1980’s. The Dean Cave stopes for which we have production records averaged 0.229 oz/t (7.8 g/t) Au, 5.83 oz/t (200 g/t) Ag from 291 ore cars (Silver Viking Corp., 1980, map DM0-08; These records are historical and have not been verified).
The DMEA refers to the area that was briefly mined around 1954 following a loan being granted by the Defense Minerals Exploration Administration for development costs. Material generated averaged 0.69 oz/t Au, 50.5 oz/t Ag, 29.4% Pb. The Deadbroke area is around 500 metres south of the Wabash/Williams historic mining area, where the 2024 drill program was focused, and at surface a number of patented claims sit, which are owned 100% and include Old Put and Antelope.
North Peak’s flagship property is the Prospect Mountain Mine complex which lies in the Battle Mountain Eureka trend, in an area known as the Southern Eureka Gold Belt, where three styles of mineralization have been identified, gold, silver Carlin style mineralization, Carbonate Replacement gold, silver, lead, zinc mineralization (CRD) and carbonate hosted Porphyry Related Skarn lead, zinc and gold mineralization associated with cretaceous intrusions. At the property, the CRD mineralization is heavily oxidized to depths of at least 610m (2,000ft) below the top of the ridge line.
A Plan of Operations is in place which covers part of the property and entitles an operator to pursue surface exploration (totalling 189 acres), underground mining of up to 365,000 tons per annum and certain infrastructural works.
