| ABSTRACT: | The first phase of exploration drilling of the Las Tapias Project has been completed. Eighteen diamond holes were drilled to test the lithium oxide content of a known large spodumene bearing pegmatite at the Las Tapias Mine in Cordoba Province, Argentina. Best assay results are listed in Table 1. Drillholes LT‐18‐01 and LT‐18‐02 were abandoned when they intersected underground workings. Holes LT‐18‐03, 04, 05 and 12, intersected potentially spodumene ore grade pegmatite in the vicinity of these workings. All other exploration holes intersected the host pegmatite, but without economic grades of lithium oxide. Although evaluation work continues at site, exploration to date suggests that Las Tapias will be unable to support the conceived modular spodumene concentrate operation as a stand‐alone supplier, and additional sources of spodumene will be required to justify its development. On the basis of the initial fieldwork, Las Tapias presented as a highly prospective lithium spodumene pegmatite project, being an existing mine/quarry with historical underground workings. Site observations, sampling and assaying undertaken, and the overall geological exploration work completed prior to drilling provided highly encouraging indications of prospectivity. Drilling was intended to confirm what was presented. However, the rich spodumene zone was not as extensive as predicted because of chemical and structural features of the pegmatite, and a large portion of the pegmatite had low lithium grades. Whilst the drilling results were not as expected, we have learned a great deal about pegmatites and lithium bearing spodumene in this new hard rock province of Argentina, which will be a significant advantage going forward for our other larger and higher priority targets in San Luis province (as per the San Luis province projects including El Totoral below). | |
