Sabodala-Massawa mine

Sabodala-Massawa is the largest producing gold mine in Senegal and has been in operation for over a decade. The mine was acquired as part of Endeavour’s acquisition of Teranga in February 2021.

Endeavour has expanded the Sabodala-Massawa mine with the addition of a new BIOX processing facility. The new processing facility adds incremental production of 1.35Moz at a low AISC of $576/oz over its mine life. First gold was poured at the BIOX processing facility on 18 April 2024.

Lafigué mine

The Lafigué mine poured first gold at the end of Q2 2024 and is Endeavour’s newest cornerstone mine. The goal at Lafigué is to produce over 200koz per year at an industry leading all-in sustaining cost of approximately $900/oz for at least 13 years.

Tanda Iguela project

At the Tanda-Iguela greenfield property Endeavour has delineated a 4.5Moz Indicated resource at 2 g/t Au for the Assafou deposit, demonstrating its Tier 1 asset potential and ranking as one of the most significant discoveries made in West Africa over the last decade.

Mana exploration

The primary objective is to increase the mine life to 10 years, and Endeavour sees considerable additional opportunity remaining with the five year discovery target for Mana now set for 1.0 to 1.5 million ounces of Indicated resources at a discovery cost of less than US$30/oz.

Lafigué exploration

Lafigué is a greenfield discovery where over 3Moz of M&I resources have been discovered since Endeavour commenced drilling on the asset in 2018. Given the strong exploration potential, Endeavour is targeting the discovery of 1.2 – 1.8Moz of Indicated resources over the 2021 and 2025 period.

Exploration potential

Sabodala-Massawa is a tremendous asset with the potential to get even better. The main prolific structure on site has been woefully underexplored. During an exploration review, Endeavour identified and delineated more than 15 potential targets within 30 kilometers of the Sabodala plant. Endeavour has established a target to discover between 2.3 and 2.7 million ounces of Indicated resources at a discovery cost of less than $26/oz over the next five years. Endeavour is particularly excited because these targets only cover half of our 1,240 square kilometre land package. As the Company continues to broaden its exploration area, the number of potential targets on site is expected to grow.

Endeavour's goal is to add high-grade ounces that will help ensure the plant is operating at its maximum capability for as long as possible. While Endeavour sees additional upside within the combined Sabodala-Massawa envelope for both refractory and non-refractory resources, the short-term focus is on the non-refractory resources. Endeavour's exploration efforts this year are mainly focused on Samina, Tina, Sofia North Extension and Bambaraya targets.
