Appears to have been an open pit mine years ago with very good grades.
NORTHERN LIGHTS RECEIVES PERMIT TO DRILL TIN CUP PROSPECT AT SECRET PASS
2021-06-08 09:45 ET - News Release
Northern Lights Resources Corp. has received approval from the Arizona State Land Department to commence drilling at the Tin Cup prospect at the company's Secret Pass gold project in Mohave county, Arizona.
Chief executive officer of Northern Lights, Jason Bahnsen, commented: "Historic RC drilling at Tin Cup in the 1980s intersected steeply angled veins with grades up to 40 grams per tonne gold. We are excited to begin drilling at Tin Cup where we plan to confirm the previous high-grade RC results with large diameter HQ diamond core drilling and test the system to a depth of approximately 350 metres, well below the maximum historic drilling depth of 180 metres.
Tin Cup zone
Records show that there was an historic small scale open pit and underground mine located at Tin Cup. The mine reportedly produced several hundred tons of mineralized material grading 15 g/t to 31 g/t of gold. Historic workings, from approximately 1918 to the early 1930s, included an open pit and an inclined shaft to a depth of 21 metres (70 feet) with minor underground level workings.
The Tin Cup gold zone is localized along the steeply northeast-dipping Frisco mine fault. The gold mineralization is hosted by tertiary andesite and associated with themargins of rhyolite dikes that occur as lenses within the Frisco mine fault. A few of the deepest historic drill holes intersect gold mineralization in the Proterozoic basement granite.
