MOUNT HAWTHORN, WA, [9 August 2023] – Summit Minerals Limited (ASX: SUM, “Summit” or the “Company”) and in-country partner, Ashgill Morocco (“Ashgill”), are thrilled to update shareholders on the latest exploration activities at the Ahmed Antimony Project (AAP) in Morocco.
Geological Mapping: Geological mapping and rock chip sampling have been completed across the majority of the AAP.
Antimony and Copper: Occurrences of antimony and copper-bearing rocks were identified during the mapping.
Gallium Discovery: Stream sediment geochemistry outlined anomalous gallium (Ga), with values up to 5.56ppm, in several drainages extending over a 5 km length.
Rare Earth Elements and Gold: Several intrusives were mapped, forming possible sources for rare earth elements and gold mineralisation.
Stream Sediment Survey: Results from the stream sediment survey have been received and are being assessed.
During the current mapping campaign, Ashgill geologists identified occurrences of stibnite (antimony) mineralisation in the southern and northern research licenses (cf. tenements); and copper sulphides (chalcopyrite, bornite) and the oxides malachite and azurite in the northern research license.
Several intensely altered alkaline intrusive plugs or stocks are emplaced along the faulted quartz-filled contacts between sandstone and sulphidic graphitic shale, raising the potential for skarn mineralisation. Skarn deposits are economically valuable as sources of metals such as tin, tungsten, manganese, copper, gold, zinc, lead, nickel, molybdenum, and iron.
During its preliminary assessment of the recently received stream sediment geochemistry, Ashgill and the Company noted several areas of anomalous gallium (Ga) results, including an area that extends over 5km in length and corresponds with a structurally disrupted zone. The significance of the numbers and the source area is yet to be investigated.
Exploration Manager, Mr Jonathan King, stated,
“Outcropping copper-bearing gossans and stibnite mineralisation, the witnessed structural complexity, and the continuity of gallium numbers over the 5km length implies things are happening in the hinterland at Ahmed. Though it remains early days, these occurrences excite both Ashgill and Summit.”
