Hemlo 16 g/t gold hit at South‑Rim: structural and resource notes for mine planners

30 Second Briefing
Hemlo Mining has reported a standout intercept of 16.1 g/t gold over 8.1 m from 99 m depth in South‑Rim hole 7652606 at its Ontario mine, including a 2 m interval at 59.7 g/t, as part of a 130,000 m 2026 drilling campaign. South‑Rim sits 50–150 m from the producing C‑Zone and is interpreted as part of a plunge‑controlled structure extending >1.5 km vertically within a 300 m‑wide east‑west corridor, with five underground and one surface rig currently active. All seven completed South‑Rim holes hit mineralisation, which remains open along strike and down plunge, while step‑out work is shifting east towards the largely untested B‑Zone.
Technical Brief
- Mineralisation comprises pyrite–pyrrhotite–magnetite with accessory barite, roscoelite and molybdenite in altered host rocks.
- Gold occurs in sub-parallel lenses associated with silicification and carbonate alteration, implying structurally controlled fluid pathways.
- Hole 7652603 returned 11 m at 5.79 g/t from 124 m downhole, confirming continuity at shallow levels.
- Hole 7652607 intersected 5.7 m at 3.44 g/t from about 149 m, extending mineralisation down-dip.
- South‑Rim was prioritised based on reinterpretation of legacy drill data and proximity to existing C‑Zone infrastructure.
- Seven of a planned 20 South‑Rim holes are complete, all intersecting gold-bearing structures, supporting the new structural model.
- Hemlo is ~20% through a 130,000 m 2026 drilling programme underpinning a resource update targeted for H2 2027.
- Carcetti Capital acquired the Hemlo operation from Barrick Mining for about C$1.5 billion in November, resetting development strategy.
Our Take
Hemlo Mining’s South-Rim results follow the earlier definition of the nearby E-Zone at the Williams property (10.9 m at 4.6 g/t gold, 26 Jan 2026), suggesting Carcetti Capital is systematically testing multiple high-grade splays off existing Hemlo infrastructure rather than betting on a single new lens.
