JV Article: Summa Silver exploration in Southwestern US revives historic silver-gold camps

Within the spring of 2020, when many mines around the globe had been grinding operations to a halt, a bunch of seasoned exploration geologists noticed a chance to amass belongings within the minerals-rich Southwestern US, and so fashioned a brand new firm, Summa Silver (TSXV: SSVR).

Led by CEO Galen McNamara, co-winner of 2018 PDAC Invoice Dennis “Prospector of the Yr” Award, 2016 Mines and Cash Exploration Award and former senior challenge supervisor – Exploration & Improvement at NexGen Vitality, Summa Silver acquired 100% possession of the Hughes property in Nevada in March 2020 within the Tonopah District. Found in 1900, the district turned referred to as the Queen of the Silver Camps.

The Nevada bundle is called after the famed Howard Hughes – who was one of many former homeowners.

The Tonopah mining district is an intermediate sulfidation epithermal vein system. Productive veins within the district are hosted in volcanic rocks which vary in composition from andesite to rhyolite. Excessive-grade mineralization within the veins consists of argentite, polybasite, electrum, sphalerite, galena and chalcopyrite, based mostly on historic information.

The Belmont Mine was one of many top-producing mines of the Tonopah district and was one in all America’s nice silver producers of the time. Summa Silver compiled historic drill information and commenced geological modelling, going for extensions of veins, parallel constructions and found unexplored areas surrounding Belmont – 3,969 acres alongside a 5.5 km strike size with freeway and powerlines on the property.

The corporate started drilling in June 2020  and has since drilled 50 holes on 4 targets and hit excessive grade silver on all of them on a strike size of three and a half kilometres.

“We’re on the lookout for an extension of your entire district..we’re on the lookout for one other 200 million ounces,” says McNamara.

Summa Silver has accomplished 10,000 metres within the 2021 drill program. Because the remaining assay outcomes change into accessible, emphasis will shift to refining targets on unexplored areas of this potential property and finalizing a drill a brand new program for each step-out holes round lately drilled high-grade intersections and holes focusing on new discovery.

Drilling is in progress on the Consolidated Extension goal the place the corporate anticipates {that a} minimal of 15,000 m of drilling is important. This primary goal represents just one.5% of the overall vein and construction strike size current on the property.

Drill highlights from Belmont mine embody 4,408 g/t AgEq over 2.8 m, 3,760 g/t AgEq over 2.5 m and 1,699 g/t AgEq over 4.3 m.

“When these mines shut down, within the late Nineteen Twenties, they had been shuttered and nearly nobody has completed any exploration since – their strategies of exploration had been a lot much less environment friendly. A lot of the exploration they did was underground –  driving drifts alongside constructions on the lookout for ore shoots,” McNamara says.

Mogollon: “One of many nice remaining vein fields nonetheless left within the US

Summa additionally acquired the Mogollon property in New Mexico. Found within the 1880’s by a Sergeant within the US Cavalry who saved the invention secret till his service ended, McNamara says the Mogollon district presents a uncommon discovery alternative and has the potential to be one of many nice remaining vein fields nonetheless left in the US.

At the least 16.4 million oz Ag and 339k oz Au of historic manufacturing at grades of 298 g/t Ag and 6.16 g/t Au or 821 g/t AgEq had been reported between the Eighteen Eighties and 1942.

Summa’s floor sampling comprised 326 channel and seize samples collected from the intensive variety of floor prospect pits and trenches current on the property, most of which had been beforehand unsampled. Ongoing investigation of the historic mines on the property has revealed good entry to underground workings in a number of areas. Systematic sampling will start within the Final Probability Mine the place sulfide-mineralized quartz veins had been lately noticed.

A property vast soil survey is in progress and can give attention to the identification of blind exploration targets which can not have been acknowledged by previous operators.

 A 29 sq. km LiDAR survey was flown to supply topographic management and to establish areas of floor disturbance peripheral and alongside strike from historic workings. 400 line-kilometres of drone-based, high-resolution magnetic information had been collected to refine the property-scale structural mannequin.

Summa is focusing on 43-101 useful resource compliance on each high-grade silver tasks by This fall 2022.

“With the drilling know-how we have now immediately – we’re on the section the place the chance goes into these previous mining districts with a contemporary arsenal of weapons,” McNamara says.

“There’s numerous juice left to squeeze – numerous low-hanging fruit. Right now we’re simply attempting to determine what number of ounces we have now on our palms – as a result of the extra we drill the extra mineralization we hit.”
