i-80 Gold drills 2.9 m of 33.6 g/t Au at Granite Creek
Executive Summary
- i‑80 Gold released initial assay results from the first six infill holes at Granite Creek Underground, showing high‑grade mineralization (e.g., 33.6 g/t Au over 2.9 m).
- The company provided an update on its Cove Underground infill program, confirming robust high‑grade zones and progress toward a 2026 feasibility study that will replace the 2025 PEA.
- Both projects are expected to advance resource classifications (inferred → indicated) and support upcoming feasibility studies slated for Q1 2026.
Key Details
- Granite Creek Underground – Assay Results:
- Hole iGS25‑02A intersected primary fault structures with 33.6 g/t Au over 2.9 m and 29.7 g/t Au over 3.6 m.
-
First six holes of the infill/step‑out program continue to display robust high‑grade mineralization throughout the South Pacific zone.
-
Drilling Progress – Granite Creek:
-
20 of 40 planned holes (≈14,000 m total) have been completed; program targets conversion of inferred resources to indicated status.
-
Cove Underground – Infill Drilling Update:
- ~45,000 m of infill drilling completed over the past two years across Gap and Helen zones on ~30‑m spacing.
-
Approximately 15 % of known mineralization in Helen zone is oxidized (to be processed at Lone Tree plant bypassing autoclave); remainder is sulphide material slated for autoclaving or roasting under an existing third‑party roasting agreement.
-
Feasibility Study Timeline:
-
Both Granite Creek and Cove feasibility studies are targeted for completion in Q1 2026, incorporating updated resource estimates from recent drilling.
-
Resource Classification Outlook:
- Anticipated conversion of inferred/indicated resources at Cove to higher‑confidence categories in the 2026 FS.
-
Similar expectations expressed for Granite Creek Underground, Archimedes Underground, and Mineral Point open pit.
-
Technical Oversight:
- Release prepared and reviewed by Paul Chawrun, P.Eng (COO) and Tyler Hill, CPG (VP Geology), both qualified persons under NI 43‑101 and Reg S‑K.
Notable Quotes
“At Granite Creek Underground, the first six holes from our infill drill program continue to show robust high‑grade mineralization… These outcomes highlight the consistency of high‑grade resources and meaningful growth upside across i‑80’s underground gold portfolio in Nevada.” – Tyler Hill, Vice‑President, Geology.
