Fortuna keeps Lindero on track for first gold pour in early October

Fortuna Silver Mines says it has started the irrigation and leaching of ore placed on the heap leach pad at the Lindero gold project, in Salta Province, Argentina.

This is ahead of the first gold pour, expected in early October.

Jorge A Ganoza, President, CEO and Director, said: “In spite of all the restrictions and challenges brought by the COVID-19 pandemic, we are managing to successfully advance Lindero in a safe and secure manner for our personnel and neighbours.

“With the start of irrigation, we achieved one more key milestone in the pre-production phase as we prepare for what follows, the first gold pour at our third producing mine.”

Back in July, Fortuna said it had completed the primary and secondary crushing circuits at Lindero and it had started stacking ore on the heap leach pad.

The night shift operations at the primary and secondary crushing circuits began in mid-August and, at month’s end, daily throughput peaked at 17,400 t/d or 93% of design capacity of 18,750 t/d, Fortuna said.

This has seen 277,000 tonnes of ore averaging 0.87 g/t Au, containing an estimated 7,750 oz of gold, placed on the leach pad as of August 31.

Meanwhile, irrigation and leaching of ore on the leach pad commenced on September 1. The company also noted that pre-commissioning of the ADR (adsorption, desorption and regeneration) plant was 80% complete.

Knight Piésold and JDS Energy & Mining to work on NRG’s HMN lithium PEA

NRG Metals has selected global consulting firm Knight Piésold Consulting and engineering, project, and construction management company JDS Energy & Mining to prepare a NI 43-101-compliant preliminary economic assessment (PEA) on its flagship Hombre Muerto Norte (HMN) lithium project, in Salta Province, Argentina.

The HMN project is in the Hombre Muerto Salar, an area of active lithium production. The development strategy for HMN focuses on production of 5,000 t/y of lithium carbonate, with the potential for expansion.

A site visit was completed in December 2018 and the project evaluation and report are progressing in a timely manner, according to NRG. The report is expected to be completed during the March quarter.

NRG recently filed an updated resource estimate for HMN, which identified 571,000 t of lithium carbonate-equivalent at a grade of 0.0756% Li in the combined measured and indicated categories, with a low magnesium to lithium ratio of 2.6:1. This calculation will be used in the PEA.
