Can Peru’s new government improve the delivery efficiency of copper mine projects? The Fujimori government’s plan is not to redefine the mining regime, but to strengthen implementation instruments such as approvals, infrastructure, reinvestment incentives, and revenue distribution. However, before constraints related to communities, permitting, infrastructure, and the decline of old mines are substantially overcome, Peru’s copper ore supply is still unlikely to be significantly released in the short term.

Can Peru’s new government improve copper project execution? Fujimori’s government plan does not seek to redesign Peru’s mining regime, but rather to strengthen execution tools, including permitting, infrastructure, reinvestment incentives and revenue distribution. However, unless key constraints around communities, permitting, infrastructure and mature-mine depletion are materially addressed, Peru’s copper supply is unlikely to increase significantly in the short term.

In the manganese-based hydrometallurgy industry chain, sulphuric acid is not merely an ordinary auxiliary material, but rather a core lifeline raw material that runs through the production of all product categories, controls production costs, and influences process selection. Mainstream products such as EMM, various grades of manganese sulphate, and EMD differ vastly in production processes and have entirely distinct acid consumption structures, which also leads to completely stratified sensitivities of various manganese products to sulphuric acid price fluctuations. Every round of change in acid prices transmits from top to bottom, directly reshaping the cost structure and market dynamics of the manganese industry chain.
