Project Overview - The Toroparu Gold Project has measured and indicated mineral resources of 126.9 million tonnes at an average grade of 1.30 g/t Au, containing 5.3 million ounces of gold, and inferred resources of 22.9 million tonnes at 1.6 g/t Au, containing 1.2 million ounces of gold [5][23]. - The project is designed as a conventional truck-and-shovel open pit operation with a strip ratio of 4.7 to 1 and a mill capacity of 7.0 million tonnes per annum [5][6]. Economic Metrics - The PEA indicates an average annual gold production of 235,000 ounces, with life-of-mine cash costs of $826/oz and all-in sustaining costs (AISC) of $1,289/oz [5][21]. - The project is expected to generate total payable gold sales of $14.7 billion over its life, with an initial construction capital requirement of $820 million [5][16]. Financial Projections - The after-tax IRR is projected at 25.2%, with a payback period of 3.0 years from the start of operations [16][22]. - At a gold price of $3,600/oz, the NPV5% increases to $2.7 billion, with an IRR of 32.6% [16][22]. Development Strategy - Aris Mining has initiated a Prefeasibility Study (PFS) for Toroparu, targeted for completion in 2026, to advance the project toward construction [2][16]. - The project benefits from a large pre-production stockpile of approximately 6.1 million tonnes, which will support a smooth start-up and consistent throughput [10]. Industry Context - Guyana's mining sector is rapidly advancing, with the Toroparu project positioned as a significant development alongside the Oko West project, highlighting the country's potential as a new frontier for large-scale gold mining [13][14].
