There’s been a lot going on at the mine and our 2019 second quarter report is packed with updates on what we’ve been doing!
Mineral processing — We’ve poured the first gold! The Company has poured the first gold produced from the Bates Hunter mine in over 100 years. Although it is only a gold button, this is a landmark event for the Company, Central City and Colorado mining. We still have a long way to go – but we’re back. The Company will continue the testing process that produced this first gold and we will continue to look at the best and most cost effective production methods as we get back into full production.
Mine infrastructure — We’ve Dewatered to 300 feet!
The Bates-Hunter mine is currently dewatered to approximately 300 feet below the surface. As we dewater, we continue the rehabilitation of the shaft itself, which has progressed to the 240-foot level.. The mine’s communications have been installed to this depth and the crew is preparing this level to become the main operating area during the mine dewatering and development of a secondary escape. Existing drifts from this level continue westward toward the West Hunter shaft, where the crew is installing new ladders and landings. As of this release, three landings have been installed to a depth of approximately 75 feet.The Bates-Hunter mine is currently dewatered to approximately 300 feet below the surface.
Central City has approved the architectural plans for the installation of a roof over the existing ore bin. The Company anticipates the issuance of a building permit for this small structure in the early part of the third quarter with work beginning immediately upon receipt of that permit. This roof is an important part of the Company’s storm water management under its existing Colorado Department of Public Health and Environment water discharge permit. This will prevent storm water from contacting mineralized material produced from the underground mine.
We’ve made significant progress as we prepare to start blasting underground. The Company has installed explosive storage magazines and will be preparing to employ explosives underground toward the end of the third quarter or beginning of the fourth quarter of 2019.
This quarter’s Mine Safety and Health Administration inspection were completed with no compliance defects noted and no citations issued.
Golden Gilpin Mill — The Rehabilitation of the building begins!
The interior of the mill building has been completely “mucked out,” and the site is ready to begin the rehabilitation of the structure of the building. The City of Black Hawk has approved the architectural elements for the re-roofing of the building and the demolition of the small shop area that had been more recently installed on the historic structure. We’ve completed the removal of the existing rake classifier tub from the building. Company engineers have completed the Computer Aided Drafting (CAD) model for the unit and are preparing drawings for the vendor bid process. Repairing and rebuilding have begun on the duplex jig between the Hardinge 6x22 conical ball mill and the dual rake classifier, and the crew has begun rebuilding the conveyors in the crushing circuit. Industrial hygiene sampling by the Occupational Safety and Health Administration’s personnel at the mill demonstrated no respirable hazards to employees. Put simply, things are moving along nicely.
Clay County Mine Clean-UP — We've begun cleaning up the mine!
Clean-up of the Clay County mine site has begun. We are currently repairing storm water damage to the existing underground decline by run-on storm water diversions. The Company anticipates the completion of reclamation under the existing third-party Colorado Division of Reclamation, Minerals and Safety permit in Q3, with the submittal of a new Company-held permit application in the same quarter. Work to repair the portal structure and rehabilitate the underground workings will also begin early in Q3. Unlike Bates-Hunter, the Clay does not have a shaft but is a mine that has been worked by a series of inclines that do down four hundred feet. We look forward to the day when motorized vehicles are driving workers down and ore back up.
Bates-Hunter Mine Assay Reports
We continue to be pleased with the results of assaying.
