A zone of high-grade nickel-copper mineralization has been intersected on the southern edge of the Maturi Deposit within Duluth Metals’s Twin Metals Minnesota project in northeastern Minnesota. Drilled as part of the metallurgical program, Hole MEX276-W1 intersected 26.5 feet of 3.93 per cent nickel, 0.68 per cent copper, 0.44g/t silver, and 0.44g/t TPM (TPM = Platinum+Palladium+Gold). A follow-up hole, MEX–468, drilled approximately 300 feet to the southwest, intersected 15.0 feet of 1.52 per cent nickel, 0.99 per cent copper, 0.50g/t TPM. Crone down-hole electromagnetic surveying in MEX-468 has confirmed extensive off-hole conductivity. As the drill holes are within the margin of an extensive coincidental conductive zone, there is strong potential for additional higher-grade mineralization within this area.
The new nickel mineralization occurs as massive to semi-massive sulphides at, or immediately below, the contact between the South Kawishiwi Intrusion and the Giants Range batholith. On-time step-response data from the Crone survey indicates a zone of higher conductivity in close proximity to MEX-468, within the larger conductive zone. Higher conductivity is indicative of greater concentrations of conductive minerals, such as massive sulphides.
“Within a massive mineralized system like Twin Metals, our geologists have always believed there is potential for higher grade pods of mineralization,” said chairman and CEO of Duluth Metals, Christopher Dundas. “These new off-hole anomalies suggest that the conductive zone is extensive and requires additional drilling to test the central portions for massive and semi-massive sulphides.”
