Excellon Files NI 43-101 Technical Report for Mallay
New NI 43‑101 Report Confirms Expanded Mallay Silver‑Lead‑Zinc Resource
Excellon Resources filed its independent NI 43‑101 technical report for the Mallay Mine (Peru) on 8 April 2026. The report, prepared by SGS Canada and signed off by qualified person Allan Armitage, Ph.D., confirms the mineral resource estimate announced earlier (23 Feb 2026). Key figures:
- Indicated: 890 kt @ 195 g/t Ag, 3.33 % Pb, 4.83 % Zn → 5.57 Moz Ag, 65 Mlb Pb, 95 Mlb Zn
- Inferred: 362 kt @ 149 g/t Ag, 2.67 % Pb, 4.32 % Zn → 1.74 Moz Ag, 21 Mlb Pb, 34 Mlb Zn
- Ag‑eq total: 12.01 Moz (Indicated) + 4.00 Moz (Inferred)
The filing also notes a three‑month consulting agreement with Macky Agency Corp., granting an option for up to 200,000 shares at $0.40 each, and the issuance of 190,546 Deferred Share Units to non‑executive directors.
- Alignment with prior expectations: The resource numbers were already disclosed on 23 Feb 2026; the technical report merely validates those figures under NI 43‑101 standards.
- Market perception: Because investors had been aware of the upgraded resource, the filing is largely a compliance milestone rather than new value creation.
- Hidden risks / upside: The report confirms the larger indicated base, which supports the staged restart plan and may ease future financing. However, no additional mineralization or cost‑reduction data were introduced.
- Overall materiality: The news is positive but routine; it removes regulatory uncertainty without materially altering the company’s valuation trajectory.
Excellon Resources focuses on the Mallay Mine in central Peru, an underground silver‑lead‑zinc operation with historic production (>18 Moz Ag‑eq) and extensive infrastructure (flotation plant, power grid). The company also holds the adjacent Tres Cerros gold‑silver exploration property and other peripheral assets (Kilgore, Silver City).
