亚得里亚海在波斯尼亚生产利润丰厚的铜/金/银精矿

Dual-listed Adriatic Metals was always going to have a problem at its Vares multi-metals project in Bosnia – but it was always going to be a nice problem to have.

在瓦雷斯,各种高品位矿物的绝对大餐会上,亚得里亚海最大的问题总是要弄清楚哪些金属将主导项目经济,哪些只是信贷,哪些金属将在冶金上很好地结合在一起,生产出高回报的精矿。

Adriatic listed at 20c back in early 2018 and since then has rocketed to highs touching $1.90 on the back of drill results like 64m @ 4.6g/t gold, 537g/t silver, 0.9% Copper, 7.7% lead, 10.8% zinc and 46% barite.

最近,亚得里亚海一直在实验室里,研究和重新设计瓦雷斯的冶金可能性,以确保能够生产出最有利可图的精矿组合,而且似乎会取得一些相当大的成功。

该公司本周表示,它已经设法做到了produce a copper concentrate from its Rupice prospect within the Vares project going 25.1% copper, 9,550 grams per tonne silver and 20.9 g/t gold.

Management said that this combination of metals was over 95% payable.

据该公司称,之前生产的铜铅精矿仅需支付30%的应付款,这使得最新的铜/金/银冶金试验工作看起来相当有利可图。

Results from a “sequential locked cycle test” also produced a saleable lead, zinc and barite concentrate. These early test results strongly support the previous metallurgical testing program and in most cases, improve on them.

亚得里亚海董事总经理兼联合创始人保罗·克罗宁说:“我们对第二个冶金试验工作计划的早期结果感到高兴。如果在可行性研究中得到证实,所生产的铜精矿的质量将对精矿销售产生的总收入产生非常积极的影响,从而显著提高铜、银和黄金的潜在支付能力。”

亚得里亚海公司聘请沃德尔·阿姆斯特朗国际公司进行第二阶段的冶金试验,目的是验证铜分离成功后的连续精矿生产。

此后,该公司宣布任命Ausenco为其即将进行的可行性研究的首席顾问。

Adriatic has two key prospects at its Vares Project that is located 50 kilometers north of Sarajevo in Bosnia, the Rupice prospect and the Veovaca prospect.

Rupice矿床目前拥有940万吨的非凡矿产资源,品位为5.1%的锌、3.3%的铅、1.8g/t的金、183g/t的银、0.6%的铜和31%的重晶石。

另一个Vareštarget,Veovaca,资源量为7.4Mt,锌含量为1.4%,铅含量为0.9%,金含量为0.1g/t,银含量为41g/t,重晶石含量为13%。在1980年代,从Veovaca矿山生产中开采出锌、铅和重晶石精矿,但此后,金和银被添加到矿产资源估算中。

该项目的税后净现值高达9.16亿美元,内部资本回报率更是高达107%——这或许可以解释为什么优步成功的WA矿业公司Sandfire Resources已经爬上亚得里亚海股票市场的榜首。
