Preliminary Economic Assessment for the Toroparu Project

Aris Mining Corporation has released a Preliminary Economic Assessment (PEA) for the Toroparu Project in Guyana, outlining a long-life open-pit gold mine with robust economics and low operating costs. The project, located in the Cuyuni-Mazaruni Region, includes the Toroparu and Sona Hill deposits, which have been defined by nearly 800 drillholes. The PEA proposes a conventional open-pit mining operation with a processing plant designed to treat 7 million tonnes per annum (Mtpa) of material. The project is expected to produce 5.0 million ounces of gold, 4.9 million ounces of silver, and 260 million pounds of copper over its 21.3-year mine life, with an average annual gold production of 235 thousand ounces. The total upfront capital expenditure is estimated at $820.3 million, with a net present value (NPV) of $1.8 billion at a 5% discount rate and an internal rate of return (IRR) of 25.2%. The project is expected to contribute $2.2 billion in income taxes and $1.2 billion in royalty payments to the Guyanese government.
