Drilling to date has resulted in excellent continuity of the mineralization of the Akyanga gold project as well as achieved some of the highest-grade intersections to date. We continue our exploration effort and are working towards a significant resource update in the next couple of weeks. Equally we expect good news flow from our other projects."

About Casa Mining Ltd.

CASA is a private Mauritian registered company that is the 71.25% owner and operator of the Misisi Gold Project located in South Kivu, eastern DRC, approximately 350km south of Bukavu and 180km north of Kalemie.

The CASA licence area consists of three contiguous mining licenses (133km2), issued in March 2015 and valid for 30 years. These licenses encompass a 60km strike length of the Tanganyika graben within the Rusizian belt ("Misisi Corridor"), including the Akyanga deposit along with the Lubitchako, Tulongwe, Kilombwe and Mutshobwe prospects.

The licences have benefited from considerable capital expenditure to date, including regional geophysical surveys completed in 2011, 19,522m of diamond drilling, 2,720m of reverse circulation drilling and excavated 6,274 line metres of trenches.

At CASA's most advanced project, the Akyanga deposit, African Mining Consultants ("AMC") in June 2017 reported a mineral resource, within a US$1,250/oz gold selling price optimised pit shell, which defined a 1.05Moz JORC inferred resource @ 2.27 g/t Au (using a 1.5 g/t Au cut-off) within a lower grade envelope of 1.57Moz @ 1.65 g/t Au.
