Canada-based Cyprium Mining has completed rehabilitation of the third shaft of its Potosi silver mine in northern Mexico.
Starting in February this year, the work involved rehabilitation and improvement of the extraction capability of the shaft.
Other works included improvement of infrastructure, security and preparation of prospective mining areas at levels two to four of the mine.
Cyprium Mining chairman and CEO Alain Lambert said: "Over the last three months, we have replaced almost 1.5km of railway tracks at level 0 and at level 4.
"This includes the installation of railway tracks between an existing raise from the level 4 proposed initial mining area to shaft 3, as well as the installation of railway tracks in the level 4 mining area where much of our near-term mining activities will take place."
During this period, the company also installed new air and water tubing and rehabilitated existing equipment including two air-loaders and a small electric locomotive.
Lambert added: "Once we have re-assembled the air compressor which was brought down into the mine last week, we will turn our focus on cleaning up old stopes in level 2, 3 and 4, retrieving existing mineralised material from past mining operations and initiating drilling and blasting."
With shaft 3 rehabilitation, the company will be able to bring materials, services and equipment into the area around the shaft for near-term exploration and mine development.
The shaft has a mechanical daily extraction capability of one hundred tonnes, and will also allow for removal of mineralised material from underground development at levels two to four of the mine.
This material will be processed at Cyprium's Aldama plant, located 42km from the Potosi mine and has a capacity of 100t per day.
The company's further work at the Potosi mine will focus on the area around the shaft 3 following rehabilitation.
