Luca Mining Corp has engaged Cominvi, S.A. de C.V. to carry out core mining operations at the company’s 100% owned Campo Morado copper-zinc-gold mine in Guerrero state, Mexico.

Cominvi is, Luca Mining says, one of the largest and most respected mining contractors in Latin America with a particular expertise in underground mining. It has a well-earned reputation for delivering excellent results with the highest degree of safety and responsibility.

Working with Cominvi will allow Luca to quickly increase production at Campo Morado and will provide cost-effective access to newer mining equipment for the company’s ongoing operations. Luca Mining added: “The addition of Cominvi to our operations team will help ensure that Campo Morado can meet and exceed its daily production targets and will provide a rapid path to further increases in production and revenues without incurring significant capital expenditures. ”

Dan Barnholden, CEO of Luca Mining, said Comvini bring incredible expertise and experience to Campo Morado and will greatly enhance the company’s operational flexibility.

“The timing of this decision is fortuitous as Cominvi has just completed a major mining project nearby and, therefore, mobilisation will occur very quick,” he said. “We intend to increase our mill throughput from the current 1,400-1,600 t/d to 2,000 t/d by year end and continue to push forward to 2,400 t/d mill rate during 2025. These achievements, along with the company’s previously announced Campo Morado Improvement Project to increase metallurgical recoveries and produce higher value concentrates, will have a material positive impact on the company’s production, costs and cash flow.

“Cominvi’s seasoned team will be an important factor in the execution of these plans.”

Luca Mining is a diversified Canadian mining company with two 100%-owned producing mines in Mexico within the prolific Sierra Madre Mineral Belt. The company produces gold, copper, zinc, silver and lead from these mines that each have considerable development and resource upside.

Telson Mining, following a strong quarter of production from the Campo Morado mine, in Guerrero State, Mexico, is making plans to boost throughput and recoveries through the potential use of grinding, leaching and flotation technologies from the likes of Maelgwyn Mineral Services, Core Group and Glencore Technology.

The mine’s throughput averaged out at 58,100 t/mth in the March quarter, with total throughput for the quarter of 174,400 t being 4% higher than the December quarter. Some 11,013 t of zinc concentrate and 1,907 t of lead concentrate was produced over the period, compared with 9,974 t and 1,916 t, respectively, in the previous quarter.

Gold, silver, lead and zinc recoveries all improved, quarter-on-quarter, in the first three months of the year, the company added.

Ralph Shearing, Telson CEO and President, said: “These strong first quarter results continue to reflect our steady progression of improving the throughput and recoveries at Campo Morado. To this end, management intends to initiate a rigorous metallurgical testing program to advance through second phase testing the Leachox™ Process of Maelgwyn Mineral Services and the Albion Process™ of Core Group, both of which returned positive test results in first phase testing.”

He said this metallurgical testing program will also study the ability to increase base metal recoveries at microfine grinding with flotation recovery using Imhoflot Flotation (also Maelgwyn) and Jameson Cell (Glencore Technology) flotation technologies, both designed for such purposes.

“We are confident that additional recovery improvements are available utilising these exciting modern technologies which, if successful, can provide increased revenue streams,” Shearing added.

Maelgwyn’s Leachox Process consists of several Maelgwyn proprietary processes linked together including Imhoflot G-Cell flotation technology, ultra-fine grinding using the Ro-Star mill, Aachen Reactors and Aachen assisted cyanide destruction.

The Albion Process, meanwhile, is a combination of ultrafine grinding and oxidative leaching at atmospheric pressure. The feed to the Albion Process is refractory base or precious metal concentrates, where the sulphides in the feed are oxidised and liberated, allowing the target metals to be recovered by conventional means.
