Toronto – September 15, 2026 -- Hemlo Mining Corp. (TSX: HMMC; OTCQX: HMMCF) has returned new assay results from its South-Rim Zone at the Hemlo Gold Mine near Marathon, Ontario, including 89.89 g/t Au over 3.0 metres in hole 6702608, 14.81 g/t Au over 10.0 metres in hole 6702632, and 12.97 g/t Au over 7.0 metres in hole 6702615.
Drilling confirms 500 metres of high-grade mineralization within a 1.5-kilometre target zone
The 2026 program has now demonstrated approximately 500 metres of high-grade mineralization within the interpreted 1.5-kilometre South-Rim horizon, leaving roughly 1 kilometre of additional extent still to be tested. The zone sits just 50 to 150 metres from active C-Zone mining and existing underground infrastructure, a proximity the Company says could lower capital costs and shorten development timelines by leveraging current access rather than new infrastructure.
Company adds Conversion drilling to push mineralization toward Indicated classification
Strong and consistent grades have prompted Hemlo Mining to expand the South-Rim program and layer in Conversion drilling to tighten hole spacing and advance portions of the shoot toward Indicated Mineral Resource status. The zone remains open along strike, down plunge, and to the east and west, with deeper drilling scheduled for the fourth quarter of 2026. None of the 2026 South-Rim results were incorporated into the June 2026 Updated Mineral Resource Estimate.
