Canadian junior gold miner Helio Resource has discovered two new gold zones during reverse circulation (RC) drilling at the Porcupine Target gold project in Tanzania.

The two drill fences – Fence A and Fence B – are 200m and 600m west, respectively, of the Porcupine Target main zone.

The drilling results confirm the presence of thick zones of gold mineralisation over an 850m strike length, further extendable along strike and at depth.

The initial estimates of the RC drill data indicate that the new zones share the same geology, style of mineralisation and geometry as the main zone, which comprises a 450m strike length of gold mineralisation, according to Porcupine.

Helio says it shows the potential of resources in the area, with less than 5% of potential structures in the area tested.

“Helio is very encouraged by the new discovery of these zones of thick mineralisation in close proximity to the main Porcupine Target, where resource definition drilling is currently ongoing,” the company said in a statement.

“These results confirm the potential to identify numerous other zones and shoots of mineralisation within the 4.5km x 0.75km Porcupine-Gap target area.”

The mine plans to start RC drilling to the west and east of the current extents of the Porcupine target next month.
