Green & Gold Minerals (ASX:GG1) has reported what it says is the ‘highest-grade’ drill intercept recorded at the Copper Hills prospect within its Herberton Conductor Metals Project in Queensland.
The result came from the first drilling at Copper Hills in 45 years and Green & Gold’s maiden campaign at Herberton.
Six reverse circulation holes were completed, with three testing the main lode, one drilled east of the main trend, and two targeting Copper Hills West.
CHC003 returned 5m @ 131 grams per tonne silver (Ag), 1.05% copper (Cu), 205g/t indium (In), 0.37% tin (Sn), 9.1% zinc (Zn), and 1.1% lead (Pb) from 102m.
This included 2m @ 300g/t Ag, 2.35% Cu, 421g/t In, 0.91% Sn, 19.4% Zn, and 2.3% Pb from 103m.
Another main-lode hole, CHC001, intersected 6m @ 67g/t Ag, 0.46% Cu, 11g/t In, 4.1% Zn, and 2.7% Pb from 35m. The interval included 2m @ 120g/t Ag, 1.21% Cu, 28g/t In, 0.05% Sn, 10.6% Zn, and 6.9% Pb.
Green & Gold says the results improve on historical grades and widths while confirming tin and indium mineralisation that was not tested in previous drilling. The company says the combined historical and new results trace the main lode to at least 90m below surface, with CHC003 indicating increasing grade and width at depth.
Managing Director Quentin Hill says the outcome strengthens the case for further drilling.
“Seeing both the width and grade increase in our first drilling program at Copper Hills is extremely encouraging,” Hill says.
“These results provide strong validation of the Herberton Conductor Metals acquisition, and we aim to drill deeper at Copper Hills and other prospects as soon as we can.”
At Copper Hills West, CHC006 returned 2m @ 69g/t Ag, 1.2% Cu, and 86g/t In from 22m.
Meanwhile, reprocessing of a 2007 airborne survey identified a circular radiometric anomaly centred on Copper Hills. The company interprets the potassium-rich centre and surrounding depletion zone as the footprint of an intrusion-related hydrothermal system that could extend beneath the shallow historical workings.
At the Sentinel prospect within its Chillagoe Gold Project, RDR004 returned four gold-bearing intervals, including 2m @ 1.61g/t gold (Au) from 32m, containing 1m @ 2.97g/t Au.
Assays from two holes at Mount Gossan are expected within four to six weeks. Green & Gold says it plans to begin around 3,000m of drilling at Mount Wandoo in early September, followed by further work at Copper Hills and maiden testing of the Siberia lode during the December quarter.
