Altaley Mining has provided an update on the startup, pre-production and construction of its Tahuehueto project in Durango. The company highlighted that all the issues delaying the start-up stage of the first ball mill have been resolved. Therefore, higher sales and revenues are expected in the coming months.

In a press release, Altaley explained that Tahuehueto's first ball mill faced several problems related to the water supply and the mill’s installation. However, the company's team has resolved the problems, achieving a continuous pre-production with the first 500t/d ball mill. Altaley also explained that its processing has stabilized further, with the mill achieving production of up to 350t/d, averaging around 195t/d.

Altaley noted that the mill output is expected to remain at these levels for the next several weeks as the crushing will be carried out with a temporary cone crusher. However, the permanent crushing circuit is expected to be fully operational within the next two weeks, with which Altaley expects to increase the ball mill’s capacity.

So far, Tahuehueto has produced around 260 tons of bulk concentrate and has sent two ships with around 30 tons each to Trafigura for sale. The profit obtained from the first shipment was around US$42,000, while the second’s payment is still pending. An additional 70 tons of concentrate are currently being shipped. The company added that it estimates another 150 tons of concentrate to be available.

“Although the commissioning phase of Tahuehueto’s first ball mill has taken longer than anticipated, management is optimistic that most of the start-up issues are behind us and that the project will be able to maintain steady state production with the initial ball mill and thereby begin to increase Tahuehueto’s concentrate sales and revenue over the coming months,” said Ralph Shearing, CEO and President, Altaley Mining.

The company’s tailings storage facility is in in its final stage and expected to be ready within 45 days. For the Tahuehueto Laboratory, Altaley’s technicians are calibrating the Inductively Coupled Plasma (ICP) equipment so that it can become operational in the coming days. Furthermore, the company highlighted that the installation of the second 500t/d ball mill is planned for the next few months. The second ball mill is expected to start operations during 4Q22, with which Altaley expects to increase production toward the mine's capacity of 1,000t/d.
