Hemlo Mining Corp. Progresses with High-Grade Gold Discoveries at South-Rim

Hemlo Mining Corp. has unveiled exciting new assay results from its ongoing drilling program at the Hemlo Gold Mine, particularly from the South-Rim Zone, located near Marathon, Ontario. This announcement marks a significant milestone as the company aims to boost its mineral resource base. The results showcase significant gold intersections and indicate a promising potential for resource growth adjacent to active mining operations.

Recent Assay Results

The most compelling highlights from the recent drilling program include impressive grades of gold, such as:

• - 89.89 g/t Au over 3.0 metres in hole 6702608
• - 14.81 g/t Au over 10.0 metres in hole 6702632
• - 12.97 g/t Au over 7.0 metres in hole 6702615

These high-grade findings validate the geological model established by the company and underscore the potential for low-capital resource growth near the active C-Zone mining area, which is only 50 to 150 metres away from South-Rim.

Drilling Program Overview

Since the initiation of the exploration drilling program in January 2026, Hemlo Mining Corp. has outlined an ambitious 130,000-metre drilling strategy to update its Mineral Resource and Mineral Reserve estimates. This extensive program includes:

• - 70,000 metres dedicated to Resource Conversion Drilling, aimed at upgrading inferred mineral resources to the indicated category.
• - 30,000 metres for High-Definition Drilling to mitigate risks in near-term mine planning.
• - 30,000 metres of Growth Drilling targeting new zones of mineralization.

Thus far, the company has completed approximately 75,000 metres of drilling across all programs, with several drills operating both underground and at surface level.

Geological Context

The South-Rim Zone has been recognized as a priority target, given its geological attributes and proximity to existing mining infrastructure. The drilling at this location reveals a high-grade mineralization potential, further emphasized by the location’s advantage of near access to existing underground workings. The ongoing drilling aims to explore further east, west, and down plunge of the currently defined mineralizations.

Moreover, the geological interpretation suggests that there might be additional high-grade mineralized areas within the South-Rim structure, extending the potential for resource growth significantly. As this area has been primarily inferred as an extension of the active mineral deposit, intensive further drilling is planned in the upcoming quarters.

Future Steps

Hemlo Mining plans to continue its exploration and resource conversion initiatives well into 2026 and 2027. The North-Rim's combination with the C-Zone mining will offer a combination of opportunities for both underground and surface mining efficiencies and enhancements. In addition, ongoing results will contribute to the comprehensive update of mineral resources and reserves expected later in 2027.

CEO Jason Kosec remarked on the significance of these results, stating that South-Rim is emerging as one of the most exciting growth opportunities for Hemlo Mining. The consistent delivery of strong grades not only aligns with their predictions but also points to a substantial amount of unexplored mineral potential within the interpreted zone.

Conclusion

The recent drilling success at South-Rim marks a pivotal development for Hemlo Mining Corp., promising enhanced resource growth potential as they tap into new mineralized zones. With continued drilling planned and a solid foundation laid by this latest exploration program, Hemlo is positioning itself for future success in expanding its gold production capabilities.
