Hughes Property

The Tonopah District

Discovered in 1900, Tonopah quickly became known as the Queen of the Silver Camps. Over the next months and years, people from all over the country rushed to Nevada in hopes of making their fortunes. Over the next half century, the Tonopah district produced 175 million ounces of silver and 1.86 million ounces of gold from 8.8 million tons of rock.

“Located in the heart of the famous historic Tonopah District and covering 5km of its possible eastern extension, the Hughes Property represents a unique opportunity to both revitalize a historic district and make new discoveries in the shadows of the headframes of some of America’s great historic silver producers.”

Eastern half of the Tonopah district,  second largest historic silver producer in Nevada

Total production of 175 Moz of Ag and 1.86 Moz of Au at grades of 679 g/t Ag and 7.3 g/t Au or 1,235 g/t AgEq* from the distric

3,969 acres – 5.5 km strike length

2020 & 2021 Highlights include:

SUM21-30

3,971 g/t AgEq over 2.8 m

SUM20-06

536 g/t AgEq over 18.1 m

SUM21-31

1,529 g/t AgEq over 4.3 m

Multiple zones of >1,000 g/t Ag equivalent intersected over a 3.5 km trend, mineralized zones largely open, un-tested drill targets common

*AgEq is calculated using US$20/oz Ag, US$1,800/oz Au, with metallurgical recoveries of Ag – 90% and Au – 95%. AgEq = (Ag grade x Ag recovery)+((Au grade x Au recovery) x (Au price / Ag price)).  Click here to view silver and gold grades comprising AgEq

Quartz-adularia-argentite vein from the Belmont Mine

Geology

The Tonopah mining district is an intermediate sulfidation epithermal vein system. Productive veins in the district are hosted in volcanic rocks which range in composition from andesite to rhyolite. High-grade mineralization in the veins consists of argentite, polybasite, electrum, sphalerite, galena and chalcopyrite. The host volcanic rocks adjacent to the veins are altered to quartz, sericite and adularia. This zone of potassium-silica alteration grades outwards into an argillic zone of alteration consisting of kaolinite, halloysite, sericite, and montmorillonite, which in turn grades outwards into propylitic alteration.

The Belmont Mine

*AgEq is calculated using US$20/oz Ag, US$1,800/oz Au, with metallurgical recoveries of Ag – 90% and Au – 95%. AgEq = (Ag grade x Ag recovery)+((Au grade x Au recovery) x (Au price / Ag price)).

True thicknesses are estimated to be 70-80% of drilled intercept length

Hughes Property Discovery Potential

Potential for new discoveries on the Hughes Property is high. Many of the previously mined veins in the Company’s Belmont and Mizpah Extension mines remain open. East of the mines, historical drilling by a previous operator in 1989 intersected mineralization that was never pursued. Historically the entire Tonopah District, much of which includes the Hughes Property, was mined over a 4 km strike length in total. There is additional 5 km on the Hughes Property and it’s almost completely unexplored.
