Hemlo Mining Corp. Discovers New Cedar Creek Zone and Extends Mineralization at Depth within B-Zone by 400 Metres

HMMC · Price
Executive Summary
- Hemlo Mining released assay results from its 2025 B‑Zone underground drilling program, highlighting several high‑grade gold intercepts that extend mineralization depth by up to 400 m below current mining levels.
- Key growth‑drill holes returned 14.5 g/t Au over 3.6 m (hole 90102505) and 7.0 g/t Au over 2.4 m (hole 90102504); conversion‑drill hole 90102514 delivered 16.1 g/t Au over 3.3 m, supporting a potential upgrade of Indicated resources.
- A newly identified volcano‑sedimentary unit within the Cedar Creek meta‑sedimentary sequence was intersected, delivering up to 18.2 g/t Au over 1.0 m, representing a long‑term greenfield exploration target.
Key Details
- Program Objectives:
- Mineral resource conversion drilling – increase geological confidence for Indicated resources ~100 m below existing mine.
- Growth drilling – validate continuity of B‑Zone Footwall (BFW) mineralization to depths >400 m.
- High‑Grade Intercepts (selected):
- Hole 90102505 (Growth) – 14.5 g/t Au over 3.6 m (514.4–518.0 m).
- Hole 90102504 (Growth) – 7.0 g/t Au over 2.4 m (480.0–482.4 m).
- Hole 90102514 (Conversion) – 16.1 g/t Au over 3.3 m (231.5–234.8 m).
- Hole 90102510 (Conversion) – 4.7 g/t Au over 5.4 m (327.2–332.6 m).
- Additional Notable Intercepts:
- Hole 90102506 (Conversion) – 2.9 g/t Au over 0.7 m (338.7–339.4 m) in newly identified Cedar Creek unit.
- Hole 90102510 (Cedar Creek unit) – 18.2 g/t Au over 1.0 m (445.6–446.6 m).
- Resource Implications:
- Intercepts ~100 m below current mining are expected to support conversion of existing mineral resources to the Indicated category.
- Depth extensions and westward continuity suggest potential for additional resource growth and longer mine life.
- Future Plans:
- 2026 drilling will target near‑mine extensions of the BFW zone and further evaluate the newly discovered Cedar Creek unit.
- A mineral resource and reserve update is planned for the second half of 2027.
- QA/QC: Core recovery 90–100 %; certified reference materials, blanks, duplicates inserted; assays performed by ALS Laboratories (fire assay with AA finish, gravimetric re‑assay >5 g/t Au).
Notable Quotes
“The B‑Zone Footwall… remains open at depth, reinforcing the strength of our 130,000‑metre underground drilling program… positioning the Company for a planned mineral resource and reserve update in the second half of 2027.” – Jason Kosec, President & CEO
Materiality: Material – Positive (high‑grade, depth‑extending drill results that could materially increase indicated resources and extend mine life).
