A ground magnetic survey and pole-dipole IP geophysics have been carried out to investigate the magnetic-low and delineate possible sulphide mineralisation at depth. The IP survey identified broad zones of elevated chargeabilities, which were interpreted to be an expression of porphyry-scale sulphides at depth.<\/p>\n<p>&nbsp;<\/p>\n<p>Quantec Geoscience concluded that &#8220;All the geophysical data collected are consistent with expectation for a non-magnetic porphyry intrusive and related sulphide mineralization&#8221;.<\/p>\n<p>&nbsp;<\/p>\n<p>The Mariana exploration model is therefore a concealed porphyry copper deposit centred on the magnetic low.<\/p>\n<p>&nbsp;<\/p>\n<p>Earlier this month, Mariana struck bonanza grades of gold and silver at its Las Calandrias project in Patagonia.<\/p>\n<p>&nbsp;<\/p>\n<p>The company says there is potential for high-grade gold mineralization along the 450 metre strike vein-breccia trend at Calandria Norte, part of the Las Calandrias area in Santa Cruz Province, Argentina.<\/p>\n<p>&nbsp;<\/p>\n<p>That announcement came just a day after Mariana removed another layer of risk from Las Calandrias by acquiring the freehold surface rights to the licence area in Patagonia.<\/p>\n<p>&nbsp;<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Mariana Resources (LON:MARL) has commenced deep drilling at the La Borita copper prospect in Argentina targeting a \u201cmost attractive\u201d concealed porphyry copper deposit.<\/p>","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3,1],"tags":[],"class_list":["post-1046","post","type-post","status-publish","format-standard","hentry","category-client-press","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/posts\/1046","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/comments?post=1046"}],"version-history":[{"count":0,"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/posts\/1046\/revisions"}],"wp:attachment":[{"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/media?parent=1046"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/categories?post=1046"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/quantecgeo.com\/es\/wp-json\/wp\/v2\/tags?post=1046"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
