ALT Dr. Graham Carman, Tinka’s President and CEO, stated: “We are very pleased to release the results of the updated 2024 PEA for the Ayawilca project. We believe the results of the PEA show Ayawilca to be an outstanding polymetallic project with several improvements from the previous study. While zinc continues to be the primary revenue source, Ayawilca's polymetallic nature includes important contributions from tin and silver providing valuable commodity diversification. The updated PEA is marked by the incorporation of a smaller, more efficient, zinc-silver-lead plant and a separate tin plant and a more compact mine footprint. Despite an increase in the initial capex, due to efficiencies in the mine design there was no significant impact on valuation. The strong financial metrics include an after-tax NPV8% of US$434 million, an after-tax IRR of 25.9%, and a post-tax payback period of only 2.9 years which highlight the potential for Ayawilca to become a producing mine.”

ALT The President and CEO of Tinka, Dr. Graham Carman, stated: “Tinka is thrilled to welcome Nexa as a strategic investor in the Company, joining Buenaventura and Sentient Equity Partners as our major shareholders. Nexa’s strategic investment in Tinka, and the co-investment by Buenaventura, is a strong endorsement of our globally significant Ayawilca zinc project and of Peru as an important long-term mining and investment jurisdiction. Nexa is a dominant player in the zinc business in Latin America, owning three mines and a smelting operation in central Peru in close proximity to Ayawilca. The Private Placement investment highlights the potential synergies of a successful mine development at Ayawilca for all parties concerned. We look forward to kicking-off our work programs at Ayawilca as soon as possible, including the commencement of a drill program which will target new high grade resources as well as increased measured and indicated resources."

ALT Tinka’s President and CEO, Dr. Graham Carman, stated: “We are very excited to release the results of our updated PEA, which shows Ayawilca to be an outstanding zinc project located in a mining friendly jurisdiction, well positioned to be one of the next major zinc development projects worldwide. At current spot zinc prices (around US$1.50 per pound) the PEA shows the project to be highly profitable with a post-tax NPV8% of ~US$785 million. At our base case zinc price of US$1.20 per pound, the PEA has excellent economics with a post-tax NPV8% of US$433 million. The updated PEA takes advantage of a relatively modest initial capital as well as access to a local refinery and port.”
