“We are very pleased with the results of our 2021 exploration programme, which have helped to demonstrate continuity of mineralisation between previously completed drill holes and better delineate the distribution and controls on high grade mineralized structures within the known resource,” Craig MacDougall, Executive Vice President, Growth, said.
“The data from this programme will help improve the current deposit model and support the completion of an updated mineral resources estimation as we continue to advance towards our objective of increasing total indicated resources to above 1.5 million ounces.”
In 2021, the company completed a combined 19,952 meters in 131 diamond and RC drill holes with 22,328 assay samples (including QA/QC samples) submitted for analysis. The main objective of the drilling programme was to infill and increase confidence in the current resources estimate for the Diakha deposit.
Diakha-Siribaya Gold Project
The Diakha-Siribaya project is wholly-owned by IAMGOLD and consists of eight contiguous exploration permits which cover a total area of 596.5 square kilometres, located in the Kédougou-Kéniéba inlier of the West African Craton region of western Mali along the borders with Senegal and Guinea.
The current mineral resources estimate for the Diakha deposit (on a 100% basis using a $1,500 per ounce gold price) comprises 15.9 million tonnes of indicated resources averaging 1.20 grams of gold per tonne for 615,300 ounces of gold and 18.2 million tonnes of inferred resources averaging 1.62 grams of gold per tonne for 947,500 ounces.
Next Steps
The drilling data from the 2021 exploration programme is currently being incorporated into a revised deposit model to support the completion of an updated mineral resources estimate targeted for completion in the first half of 2022.
