格隆匯1月11日丨金誠信(603979.SH)公佈，公司日前收到參股公司 CordobaMinerals Corp. (“Cordoba公司”)關於哥倫比亞San Matias銅-金-銀項目進展的通知，該項目Alacran銅金銀礦預可行性研究(“預可研”)已完成，並由獨立的第三方Nordmin Engineering Ltd.出具了預可行性研究報吿。
該預可研對Alacran的常規露天採礦作業和礦石處理過程以及主要基礎設施建設情況進行了詳細分析，主要分析結果如下：
1、Alacran銅金銀礦牀原礦石量約102.1百萬噸，銅品位0.41%、金品位0.26克/噸、銀品位2.30克/噸。
2、Alacran銅金銀礦體服務年限13年，露天開採日均處理礦石22,000噸，年平均產銅金屬68.8百萬磅，金金屬55千盎司，銀金屬386千盎司；在生產的前6年，原生礦和混合礦中的銅、金、銀的平均品位預計分別為0.61%,0.29克/噸和3.50克/噸。
3、項目累計約回收銅849百萬磅、金0.7百萬盎司、銀4.7百萬盎司，銅和貴金屬精礦平均回收率約為銅92.5%，金78.1%、銀62.9%。銅精礦預計含有非常低的有害元素，如砷和鉛。
4、銅的運營現金成本(C1)：平均每磅2.59美元，扣除貴金屬副產品銷售收入後平均每磅1.18美元。
5、項目初始資本支出總額約為4.349億美元，服務年限內資本支出(包括維持資金、回收和關閉成本)總計約5.91億美元。
6、經濟效益分析顯示：按照銅價4.28美元/磅，金價1,778美元/盎司和銀價21.93美元/盎司計算，該項目預計税後淨現值為6.50億美元（折現率8%），內部收益率為32.7%，回收期2.4年。
7、Alacran礦牀預計為當地政府貢獻1.904億美元礦權費及5.142億美元所得税。
8、此次預可研僅針對San Matias銅-金-銀項目內的Alacran礦牀；Alacran礦牀周邊的Montiel East礦牀、Montiel West礦牀和Costa Azul礦牀未納入此次預可研報吿範圍，故其資源儲量未進行更新。
