Mati Mining Site

The Evidence Portfolio

Nine laboratories. Five countries. One deposit model.

Deposit Cross-Section

Eight core samples to 493 meters total depth across the concession

Geological cross-section — iron oxide cap, transition zone, sulfide zone, porphyry target with 8 core samples

Based on SGECS geological assessment filed with MGB Region XI, June 2025

Primary Commodities

Three minerals validated by independent laboratories across five countries

Iron Ore — 67.31% Fe, POSCO Confirmed

Shipping-grade premium iron ore — comparable to top-tier Brazilian and Australian product. Very low phosphorus and sulfur, suitable for direct export to global steelmakers.

Copper — 39.5% Cu, Near-Concentrate Grade

Near-concentrate grade at surface — indicating strong supergene enrichment above the primary sulfide system. Four independent laboratories across a decade confirm this as a systematic feature.

Gold — 20.35 g/t Au, Highest Fire Assay

Highest gold result ever recorded from this concession. Seven-year grade consistency (2017–2024) from the same laboratory confirms this is a systematic feature, not an anomaly.

Nine Laboratories, Five Countries

Each laboratory answered a different question. Together they tell one story.
