According to the company, a new study reflects an improvement in the project’s profitability and supports Porvenir as a solid mining development project.
Mineros S.A. disclosed the results of the updated Pre-Feasibility Study (PFS) for the Porvenir project in Nicaragua, which could impact the company’s operations over the next 10 years.
This project, operated through its subsidiary Hemco Mineros Nicaragua S.A., is the “cornerstone of an emerging district that includes the Guillermina, Leticia, and San Antonio deposits” in the Central American country.
It was noted, for instance, that its after-tax Net Present Value (NPV), utilizing a 5% discount rate, is US$460 million, with an after-tax Internal Rate of Return (IRR) of 37.9% and a payback period of two years in its base case.
Furthermore, an after-tax free cash flow of US$727 million over the life of the mine (LOM) was highlighted, based on US$3,150 per ounce of gold. The required initial capital expenditure (CAPEX) is US$206.8 million.
Additional Project Details
Regarding the production profile, average annual sales of 72,300 gold equivalent ounces were emphasized, comprising approximately 54,500 ounces of gold, 190,000 ounces of silver, 28 million pounds of zinc, and 3.75 million pounds of copper during the peak production years of the mine’s lifespan (years one through nine).
The study highlighted a processing plant with a capacity of 2,000 tonnes per day, along with all associated infrastructure, including a tailings storage facility, power supply via a dedicated 34.5 kV distribution line, and a wastewater treatment plant.
Daniel Henao, President and Chief Executive Officer of Mineros, emphasized the attractiveness of Porvenir’s profitability metrics.
“Porvenir is only the beginning of a confirmed polymetallic district. Nearby deposits such as Guillermina, Leticia, and San Antonio are within walking distance of shared and scalable infrastructure, and we believe we are looking at a district with the potential to exponentially expand Mineros’ operations over the next decade,” he stated.
