Belararox (ASX: BRX) has reported visual copper mineralisation above target depth at the Tambo South prospect within its Toro-Malambo-Tambo (TMT) project in Argentina.

The second hole of the company’s drilling campaign is currently at a depth of 729 metres with a planned total depth of 1,300m and significant copper sulphides have been observed above the main geochemical target depth yet to be tested.

These include supergene chalcocite, covellite, chalcopyrite and hypogene chalcocite.

First assays

Assays for the first 224m of the first hole at Tambo South included 30m at 0.13% copper from 102m and 30m at 0.10% copper from 154m, with the company expecting results for the remaining 804.6m in the coming weeks.

Belararox understands the copper mineralisation at Tambo South is hosted in a suite of porphyritic intrusions comprising dacite, porphyritic diorite, quartz diorite and hornblende diorite.

The presence of covellite and hypogene chalcocite in the second hole is consistent with Belararox’s interpreted exploration model of a high-sulphidation epithermal overprint to a copper porphyry system.

The company believes an intersection from 104m to the present 729m depth could be indicative of stronger copper mineralisation at depth.

Malambo drilling

Drilling at the Malambo copper-gold porphyry target within the TMT project is also reportedly progressing well.

The company has completed the first hole to a depth of 1,166m, with widespread quartz veins and molybdenite visible.

The second hole is currently at 48m for a planned depth of 600m and the company will be testing the shallower Halley geochemical model.

Key target

Managing director Arvind Misra said the latest results would add momentum to the company’s drilling program.

“Tambo South is a key target within our broader TMT project, which sits in a largely unexplored corridor between the world-class El Indio and Maricunga Metallogenic Belts and is an exceptional address for copper exploration,” he said.

“These early signs are pointing to a significant system and we are excited about the potential scale as we continue drilling and move toward unlocking meaningful value for our shareholders.”
