Casa Mining Update

Premier African Minerals Limited (AIM: PREM), the London listed mining and exploration company, is pleased to provide an update on Casa Mining Limited in which Premier has a 4.5% interest.

Casa Mining Limited ("Casa") is a privately-owned mineral exploration company focused on developing the Akyanga gold deposit, part of the prospective Misisi Gold Project, in the Democratic Republic of Congo ("DRC"). Casa has commenced a 5,000 metres drilling programme with the aim to increase and upgrade the existing mineral resource estimate. The first 2,200 metres are expected to be completed during October 2017.

Casa Mining Limited

Casa has a 71.25% interest and is the operator of the Misisi Gold Project located in South Kivu, eastern DRC, approximately 350km south of Bukavu and 180km north of Kalemie.

In 2014, SRK Consultants (UK) Limited ("SRK") reported an Inferred Mineral Resource at the Akyanga deposit of 5.5 Mt at a grade of 1.5 g/t Au for approximately 272koz of contained metal. SRK has further reported an Inferred transition gold Mineral Resource of 16.2 Mt at a grade of 1.8 g/t Au for approximately 927koz of contained metal.

MDM Engineering Projects Limited ("MDM"), in conjunction with SRK, completed a scoping feasibility study for an 80,000 oz year heap-leach operation at the Akyanga deposit resulting in an ungeared net present value ("NPV") (at a discount of 8%) and internal rate of return ("IRR") of US$171 million and 35% respectively at a US$1,300/oz gold price. This assumes a contract mining scenario with an initial capital cost estimate of US$87.4 million and a total operating cost of US$628/oz.

African Mining Consultants Limited ("AMC") recently completed a review and re-interpretation of the geological model of the Akyanga deposit and reported a 1.05Moz JORC inferred resource at a grade of 2.27 g/t Au (using a 1.5 g/t Au cut-off) within a lower grade envelope of 1.57Moz at a grade of 1.65 g/t Au (using a 0.5g/t cut-off grade).
