Superior Gold stock e ntse e phahama ho latela liphetho tse ntle ka ho fetesisa ho fihlela joale
Superior Gold (TSXV: SGI) e tlalehile mateano a eona a molemo ka ho fetisisa a ho cheka ka tlas'a lefatše ho fihlela joale morafong oa khauta oa Plutonic Australia Bophirimela.
Har'a likoti tse 19 (ho feta limithara tse 1,855) tse phethiloeng nakong ea lenaneo le ntseng le tsoela pele la ho phunya, litsela tse 17 li kopane le ho feta 5 g/t Au. Liphetho tse ntle li kenyelletsa: 56.3 g/t Au ho feta 15.1 metres, 10.2 g/t Au ho feta 7.1 metres le 11.9 g/t Au ho feta 5.3 metres.
"Makano a 56.3 g/t Au ho feta limithara tse 15.1 ke mateano a rona a bohlokoa ka ho fetisisa ho fihlela joale ho tloha ha re fumana mesebetsi ea khauta ea Plutonic," CEO Chris Bradbrook o boletse phatlalatsong ea litaba.
O boetse a re liphetho tsena li bonts'a monyetla oa ho lelefatsa bophelo ba ka "ho feta lilemo tse hlano tsa pele."
Ts'ebetso ea khauta ea Plutonic e nkuoa e le e 'ngoe ea merafo e meholohali ea khauta Australia Bophirima mabapi le tlhahiso e ntseng e eketseha. Meepo ea mekoti e bulehileng e qalile ka 1990 mme ea fela ka 2005, athe tlhahiso ea ka tlas'a lefatše esale e tsoela pele ho tloha ka 1995.
Likarolo tsa Superior Gold li nyolohile ka 17.4% har'a mots'ehare oa Laboraro. Mocha oa khauta oa Toronto o na le chelete ea 'maraka ea C $78.5 milione.
