HECLA-KILMER

Hecla-Kilmer - Rare Earth and Niobium Project, Ontario

District-scale, drill tested + confirmed Apatite-hosted Rare Earths advancing towards maiden resource estimate. Recent metallurgical results confirm high-leachability of Apatites, paving a possible route towards first-ever rare earth domestication.

April 1, 2025 – metallurgical results confirm leachability of REE bearing apatites at just 50°C and low-concentration HCL acid (36%)
A district-scale exploration opportunity spanning more than 3 kilometers, featuring multiple drill-confirmed zones with broad, near-surface mineralization exposed at bedrock.
Notable results include 361m of 1.02% TREO (20% PMREOs) and 0.13% Niobium Oxide (N2O5), 86m of 1.06% TREO, 342m of 0.5% TREO including 54m of 1.06% TREO, all holes started mineralization from bedrock surface.
Significant high-grade volcanic Phosphate (7%+ intercepts) component that can be blended with lower-grade sedimentary-derived phosphates to upgrade product for export.

TREO is the summation of Ce2O3 + La2O3 + Pr2O3 + Nd2O3 + Sm2O3 + Eu2O3 + Gd2O3 + Tb2O3 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Yb2O3 + Lu2O3 + Y2O3

PMREO is the sum of high-value rare earth oxides used in permanent magnet motors and turbines used in electric vehicles and wind turbines (Pr2O3 + Nd203 + Tb2O3 + Dy2O3). The % Magnet REO is this PMREO sum divided by TREO, and expressed as a percent.

Hecla-Kilmer - Leachable Apatites, processing solutions

First pass metallurgical study revealed over 75% TREO recovery, with Apatite-hosted REEs being easily leached in ~6 hours at 50°C.
Huge advantage to other deposits in North America/Europe with Monazite-Bastnäsite-Steenstrupine minerals that require high-temp acid baking (200-600°+C) for sustained periods of time, upwards of 250 hours.
With over 96% of rare earth elements successfully leached into solution, Hecla-Kilmer demonstrates that apatite-hosted REEs could represent the first viable, domestically produced source in North America—thanks to their low-impact, rapid leach characteristics.
With a high proportion of permanent magnet rare earth oxides (PMREOs), TREO values at Hecla-Kilmer translate directly into meaningful project value.
Ongoing metallurgical testing is expected to further optimize leach times, improve recoveries, and enhance beneficiation processes.

Hecla Kilmer – Size Matters

Large 3.5 x 3 km magnetic anomaly with multiple drill-confirmed zones starting at bedrock surface.
District-scale footprint with bulk-tonnage potential.
Zones remain open with clear step-out targets and untested magnetic anomalies.
Early-stage results highlight potential for scalable, multi-zone development.
