Nov 21, 2019The Block E and Block G copper anomalies were then followed up with trenching that returned assay results of 8 metres at 1.7% copper and 25 metres at 0.95% copper respectively. Following the trenching, Canadian based multinational mining group Falconbridge then completed diamond drilling which returned significant assay results from Block G
The Zijinshan gold-copper mine, in spite of the low-grade nature of the ore, has become one of the largest production-scale and most profitable non-ferrous metal mines in China. The successful application of hydrometallurgy as well as proper engineering design are the key factors for large-scale development of the Zijinshan gold-copper mine. In this contribution, the practical experience
The Bayugo copper-gold prospect is similar to the adjacent Boyungan Copper-Gold Porphyry Deposit that Anglo-American is exploring under a separate venture with Philex Mining Corp. Together, Bayugo and Boyungan would make another world-class gold-copper project that should further firm up the Philippines' place in the world mining

Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining
A South American copper mine made significant capital expenditures to boost its production and saw output rise 3.9 percent per year (Exhibit 7). However, while productivity has started to increase in the past four years, helped by the higher output, the increased outlays on labor and, in particular, on operating costs across the full 2005

The history of opal mining in Australia is one of danger, regeneration, and success against great odds. As far back as 4,000 BCE, humans have treasured opals and mined them in various locations, such as Kenya and Hungary. However, due to an unlikely combination of geology, fortuitous finds, and the two world wars, Australia has become the world's primary source of opal since the 1880s.
