Identifies Porphyry Copper-Gold Targets At Burn Project
Commander Resources Ltd (TSXV: CMD) has identified four porphyry centres including a large Central Zone at the Burn property located 100 km NNE of Smithers, British Columbia.
The project is subject to an earn-in agreement with Freeport-McMoRan Mineral Properties Canada Inc. for Freeport to earn a 75% interest in the large 16,000 ha Burn Property.
A gold-rich section of the target is associated with a prominent magnetic high and remarkably high gold in soil values (4 soil samples >1000 ppb Au with the highest at 3,929 ppb Au) over one km by 0.5 km
Work by Commander, funded by Freeport, included a property wide airborne magnetic survey (200 m spaced flight lines) which has outlined two prominent circular magnetic rings and several linear magnetic highs that coincide with stocks and dykes of Eocene age.
A property-wide sampling programme of stream sediment sampling, soil and rock sampling, and geological mapping has identified four alteration zones of which the largest is referred to as the Central zone.
The Central zone is underlain by numerous phases of feldspar-biotite-hornblende monzonite and quartz monzonite dykes and stocks exhibiting alteration from chlorite, to chlorite-magnetite, and moderate quartz-sericite-pyrite (QSP) to intense QSP with local quartz veinlets. In one location, angular boulders of K-feldspar-biotite-magnetite altered feldspar-biotite porphyry monzonite with sheeted and stockwork magnetite-quartz veins with K-feldspar haloes was discovered.
Reconnaissance soil sampling in the Central zone has identified several anomalous Au-Cu and Mo areas including one discrete region on the west side where three samples over a distance of 300 m returned 500 ppb Au to 3900 ppb Au.
Silt sampling from one of the north flowing creeks draining the Main zone returned anomalous Cu-Mo-Au throughout. In 2020, 23 samples were collected around the anomalous gold in soil samples including samples of talus fines collected directly downhill from soil sample pits.
Rock grab samples include four samples greater than 250 ppb Au including one sample of 1,586 ppb Au with low Cu tenors, again typical at high-levels in porphyry Cu-Au systems.
In October, the company received a multi-year exploration permit for drill testing and ground base geophysics.
