2016年發(fā)布的可行性研究表明，該礦山使用壽命為24年，運(yùn)營(yíng)成本為0.65美元/磅，初始資本成本預(yù)計(jì)為4690萬(wàn)美元。
根據(jù)可行性研究，Excelsior期望使用現(xiàn)有的Johnson Camp礦山設(shè)施實(shí)現(xiàn)每年2500萬(wàn)磅陰極銅的初始生產(chǎn)速度。項(xiàng)目中期，每年擴(kuò)展到7500萬(wàn)磅，直至運(yùn)營(yíng)第七年，達(dá)到每年1.25億磅的完整產(chǎn)量。
Excelsior此前曾表示，Gunnison銅項(xiàng)目有可能成為北美成本最低的銅生產(chǎn)商之一。該公司期待在2020年擴(kuò)大現(xiàn)有業(yè)務(wù)，并為將來(lái)擴(kuò)大Gunnison銅項(xiàng)目的年產(chǎn)能到1.25億磅奠定基礎(chǔ)。
