The Bureau of Land Management (BLM) in mid-August authorised the CS Pozzolan-Perlite project and a customary appeal period followed, though the company today confirmed that no objections were received.
"We are pleased to see that the various appeal periods are passing without any objections or appeals and that we now have a clear green light for the mine development from both the BLM and BMRR,” Patrick Cheetham, Sunrise chief executive said in a statement.
“I think this reflects the thorough work that went into the Environmental Assessment and the positive green credentials of the CS Project."
Sunrise noted that the appeal period for the mine reclamation permit by the Nevada Bureau of Mining Regulation and Reclamation (BMRR) has also passed without objection. Meanwhile, the Nevada Division of Environmental Protection's decision to award a Class II Air Quality Permit for a minerals processing plant is open to comment and objection until September 11, 2020.
The CS Project has an envisaged 27-year mine life, producing both perlite and natural pozzolan.
Pozzolans are used as a direct additive to concrete mixes and as a partial replacement for cement, while, perlite – a glassy raw material which expands ‘popcorn-like’ some 20-times when heated – is used in various industrial and household applications such as insulation, paint texturing, and building materials.
