Sierra Nevada Gold begins search for JV partner at Blackhawk Project in Nevada, US

Precious and base metals explorer Sierra Nevada Gold (ASX:SNX) has begun talks with several parties regarding a potential joint venture (JV) to advance its Blackhawk Copper-Gold Project in Nevada, US.

The company reports an exploration partnership on the Blackhawk porphyry will allow it to focus on the ‘company-making’ Warrior Gold Silver Project, which is also in Nevada.

Sierra Nevada reports it has designed a 2,500m drilling program at Warrior to target the historically mined ‘high-grade’ Warrior, Hillside, Cute Maid, and Lou veins and their extensions. 

Drill planning has been guided by recently completed rock chip sampling, which returned grades of up to 74g/t Au, along with vein texture interpretation, geological mapping, and the maiden drilling program completed in 2022. The company reports it plans to begin its new drilling program at Warrior in July, with results expected in Q3 2023.

Additionally, the company has designed a 1,900m drill program at the Endowment Mine prospect within Blackhawk. This program is set to begin in Q3 2023 and aims to follow up on the results of hole BHD006, which was drilled in 2017.

Hole BHD006 returned an intercept of 12m @ 219g/t Ag, 0.36g/t Au, 3.05% Pb, and 8.54% Zn from 250-262m, including a ‘high-grade’ core of 5m @ 479g/t Ag, 0.73g/t Au, 6.96% Pb, and 19.84% Zn from 256-260m.

Sierra Nevada says this hole was drilled beneath the historic Endowment mine to test for depth extensions of historically mined veins and intersected the Contact Vein 240m vertically below surface. This greater-than-200m down-dip extension of the vein from surface attests to the ‘strength and predictability’ of the vein system at Endowment and gives the company encouragement for future discovery.

Commenting on a potential partnership, Sierra Nevada Gold Executive Chairman Peter Moore says: “Following completion of our most recent diamond hole at the Blackhawk project, we have decided partnering is the appropriate way to advance exploration on this large-scale copper-gold project, and we have commenced discussions with several potential partners with the aim of securing an agreement over the project in the medium term.

“…we have decided partnering is the appropriate way to advance exploration on this large-scale copper-gold project…”

Attracting a partner to help advance exploration and development of the Blackhawk porphyry target will enable SNX to focus on exploring the large epithermal systems at Warrior and Blackhawk, which both have the potential to host company-making gold discoveries. To that end, SNX is moving ahead with plans to resume drilling at Warrior in July, with drill targeting completed and permitting now underway.”

Sierra Nevada reports the Blackhawk epithermal vein system is prospective for ‘high-grade’ structurally controlled silver-gold and base metal deposits that are partially coincident with, and adjacent to the northern edge of the ‘extensive’ Blackhawk porphyry system.

The company says the epithermal vein system covers an area of about 5km-square and contains up to 22-line kilometres of mostly untested veins. Additionally, at least 8 historic mining areas were operated within the Blackhawk epithermal vein system between the 1860s and the early 1900s, with the main mining areas around the Endowment, Morning Star, and Blackhawk mines.

Sierra Nevada Gold is an ASX-listed precious and base metals explorer focused on its portfolio of gold, silver, and copper-gold porphyry projects in Nevada, US. These projects include Blackhawk, Warrior, New Pass, and Colorback projects.

Additionally, the company has established a grassroots generative program to detect large-scale hydrothermal systems capable of hosting tier-1 deposits within the underexplored Walker Lane Trend in southwestern Nevada.
