Big Hits: Haranga delivers US Mother Lode gold masterclass

Big Hits looks at notable drill hits reported to the ASX this week, led by Haranga Resources’ underground gold intersection with a blistering 32 metres at more than 10g/t gold in California. West Musgrave-focused runner-up Terra Metals landed a massive, near-surface PGE broadside exceeding 190 metres of continuous shallow mineralisation, while Amara Minerals cracked a 102-metre intercept to reinforce the structural architecture of its premier Victorian gold-antimony system. So let’s dive in.

Project: Lincoln gold project, California, USA Hit: 32m at 10.41g/t gold from 143m downhole

High-grade underground mining exploration thrives on structural continuity, and this week Haranga Resources claimed the top step on the podium after turning a meticulous dewatering campaign to gain access into a spectacular high-grade gold revelation.

Undertaking the first diamond core holes of its highly anticipated Phase 2 underground drilling program at the company’s historic Lincoln gold project, the company delivered a monumental bedrock intercept from the very first rod put down the hole.

The standout diamond hole, drilled from the recently restored XC11 development level into a little-tested zone along the southern edge of the existing resource, sliced through a tightly folded, structurally controlled gold system to deliver a spectacular 32m at 10.41 grams per tonne (g/t) gold from 143m downhole.

Highlighting the remarkable grade distribution and absolute tenor within the core of this system, the single continuous interval generated an extraordinary 13 separate one-metre sample assays that exceeded 10g/t.

The high-grade distribution peaked with a blistering one-metre individual assay roaring up to 51.4g/t gold from 152 metres downhole, validating the genuine bonanza nature of the mineralisation.

What makes this performance globally significant is that the breakthrough hit successfully bridged the spatial void between two previously separate, thinner modelled lodes.
