Solis Minerals Ltd. has received the assay results from the first two holes (MODD001 and MODD002) of the Company's first phase of drilling at the Mostazal Copper Project in Chile ("Mostazal" or "the Project"). A total of four holes were drilled, with results from holes MODD003 and MODD004 pending. All drill holes encountered widespread alteration with core logging highlighting widespread sulphide mineralisation from traces to +1% sulphides.

The sulphide minerals observed include chalcopyrite, bornite, primary chalcocite and lesser pyrite. Holes MODD001 and MODD002 aimed to test the southern and down-dip extensions respectively, of a near surface copper manto system. Drilling showed an extensively altered system characterised by chlorite + epidote + albite +/- hematite, with copper mineralisation represented by chalcopyrite, bornite and primary chalcocite sulphides.

Initial observations from the detailed structural surface mapping program have identified a large asymmetrical anticline with an NNW-SSE trending axis, plunging due south. This mega structure is defined by thick, well-stratified violet-coloured porphyry lavas, massive greenish aphanitic lavas, and minor reddish tuffs from the Jurassic Sierra de Fraga formation. A second-order system has been mapped at Mostazal, defined by a series of NNW-SSE faults and veins, which sections the large structure mainly along its axis and in the west limb.

A third system has also been identified, comprising a series of WNW-SSE dextral faults. The NNW-SSE and WNW-ESE faults show carbonate, opal silica or carbonate, opal silica fracture fill, with some copper oxide (green) and sulphides (primary chalcocite) observed. The significance of these initial observed structures, and their significance to the wider mineralised system at Mostazal is still to be fully understood.

Once the mapping has been completed, this data will be integrated with the historic and new drilling information (including assay results for MODD003 and MODD004 which are yet to be received from the laboratory), enabling the reinterpretation of the Mostazal system.
