East Africa Metals - Updated Magambazi Mineral Resource Estimate

VANCOUVER, Oct. 19, 2021 - East Africa Metals Inc. (TSXV: EAM) ("East Africa" or the "Company") is pleased to provide the updated Magambazi mineral resource estimate.

As previously announced (Press Release - September 27, 2021), PMM Mining Company Limited ("PMM") has commenced engineering work to develop detailed plans for mining operations and surface equipment installations. Once complete, the first-year production is targeted to be 10,000 ounces of gold, scaling up to 40,000-ounces annually over a period of 48 months. Updating of the Magambazi mineral resource has also been part of the project review.

Elements of the mineral resource update included developing a new block model that incorporates rock density data from a total of 468 drill holes rather than 400 diamond drill holes used to develop the mineral resource calculation disclosed by EAM in a NI 43-101 report in 2012. The new updated block model reports an improved mineral resource estimate of Measured and Indicated Category to 15.3 million tonnes grading 1.99 grams per tonne gold and containing 975,589 ounces in the indicated category, representing a 34% improvement on grade and a 35% improvement of ounces over the 2012 calculation.

The bulk of the inferred resource in 2012 mineral resource estimate has been upgraded to the measured and indicated category based on the new study.

"EAM's management is pleased to see the increase in confidence in the continuity of grade and structure of the Magambazi resources based on a rigorous technical study using an expanded dataset," said Andrew Lee Smith, CEO of East Africa. "This upgraded mineral resource will provide a solid foundation for mine planning and the potential for improved operating efficiencies."

The update of the 2012 resource in accordance with JORC standards was completed by Geofields Tanzania Limited, a consulting firm with in-depth experience in preparing resource estimations for Tanzanian gold projects. This work closely studied structural controls on mineralization that appear to be an important element of the continuity of the mineralizing system not considered in the original mineral resource disclosed by EAM in the 2012 NI 43-101 report.

Andrew Lee Smith, P.Geo., C.E.O., a Qualified Person under the definitions of National Instrument 43-101, has reviewed and approved the technical contents of this press release.

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. The quantity and grade of reported inferred mineral resources as the estimation is uncertain in nature and there has been insufficient exploration to define any inferred mineral resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading inferred mineral resources to an indicated or measured mineral resource category. The contained gold, copper and silver figures shown are in situ. No assurance can be given that the estimated quantities will be produced. Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended.
