Galileo Mining Ltd (ASX:GAL) has announced that it has intersected semi-massive sulphide mineralisation from the first of two drill holes at the Delta Blues DB2 prospect within its Fraser Range Project in Western Australia.
Two RC drill holes for a total of 428m have been completed at the prospect, with a third drill hole already underway.
The company reports that the semi-massive sulphides consist primarily of pyrrhotite and minor chalcopyrite (copper) at intervals ranging from 190m to 192m from hole DBRC001, and 167m to 170m from hole DBRC002.
The top of the electromagnetic target at the Delta Blues DB2 prospect was confirmed to be sulphide-related, with the strongest and most valuable parts of the conductor not tested at depth. These intersections may indicate a new type of Fraser Range mineralisation, with sulphides occurring together with mafic and felsic intrusions.
Upon completion of drilling at Delta Blues DB2, work will progress to testing the “highly conductive” DB1 target.
Fraser Range Project
The Fraser Range Project includes exploration licences covering a 602 km² area in the Albany-Fraser Orogen, with Galileo owning 67% of Fraser Range Tenements in its search for magmatic massive sulfuride-nickel-copper deposits.
The Albany-Fraser Orogen’s dominant feature is the north-trending Fraser Zone, which is mainly composed of metagabbroic rock interlayered with sheets granitic and gneisses. This group of metamorphic rocks with high grades has a distinctive geophysical signature both in aeromagnetic as well as gravity data.
The project spans two areas: the northern Kitchener zone, which houses the company’s Lantern & Nightmarch prospects, and the southern Yardilla area which contains the Empire Rose & Yardilla South prospects.
Galileo describes the location of the project within the nickel-copper bearing Fraser Range Zone as “ideal” , with access to infrastructure including the main Eyre highway.
“The geological results from the first round of drilling at our Delta Blues prospect are highly encouraging with sulphides in both holes drilled to date”
Management comments
Galileo Mining Managing Director Brad Underwood said: “The geological results from the first round of drilling at our Delta Blues prospect are highly encouraging with sulphides in both holes drilled to date. The mineralisation appears related to mafic and felsic intrusions which is unusual for the Fraser Range and possibly the first time this association has been identified in the region.
Assay results and microscope petrography will provide us with a guide to the economic potential of the prospect while a follow up diamond drilling program is designed to test the better parts of the EM conductor at depth.”
