Mkango Announces Rutile and Ilmenite Discovery in Malawi
September 15, 2020
London / Vancouver: September 15, 2020 – Mkango Resources Ltd. (AIM/TSX-V: MKA) (the "Company" or "Mkango") is pleased to announce the results of a reconnaissance shallow soil sampling and auger programme in its 869 square kilometre (“sq km”) Mchinji licence (EPL 0544/19) in Mchinji district, Malawi, held by Mkango’s 100% owned subsidiary MKA Exploration Ltd.

The results demonstrate the presence of interesting grades of rutile plus anatase (both naturally occurring mineral forms of titanium dioxide: TiO2) mineralisation of up to 1.07%, with overall TiO2 grades in the range 0.51 to 4.10% in auger samples and 0.14–2.38% in soil samples; also ilmenite grades of 1.30 to 3.40% (average 1.85%) – see table below.
The grade of the TiO2-bearing minerals in the highest-grading auger hole are in the range of 0.63 to 1.07% rutile plus anatase (average 0.73%) and 1.30 to 3.40% ilmenite (average 1.85%), hosted in free-dig saprolite material from surface.
Mkango’s President Alexander Lemon commented:
“Mkango is focused on developing the Songwe rare earth deposit in Phalombe district in Malawi and is looking forward to completing the feasibility study. We are very pleased to add this new rutile and ilmenite discovery to our portfolio of projects in Malawi. These early stage results show similarities in terms of saprolite-hosted mineralisation to the recent rutile discoveries made on the adjoining Sovereign Metals Ltd licence to the east, and suggest the potential for discovering high-grade rutile deposits within Mkango’s large licence area, in what could potentially be a new province of rutile mineralisation.”
Twelve vertical auger holes were drilled to depths of 0.45 to 9.40m, for a total of 35.8m, from which 41 samples were collected. Available equipment was not able to penetrate beneath a shallow ferricrete horizon in the Ludzi river channel to test the assumed river sands beneath, and eight holes failed to reach more than 2m depth; new auger exploration equipment with improved ground cutting capability has been purchased and is currently being shipped to Malawi. The other four holes were drilled in saprolite on higher ground between the Ludzi’s tributaries.
Soil sampling was carried out in pits dug to 50cm (‘B horizon’) on a 500m staggered grid in four areas of the licence, producing 134 samples.
Sample preparation and analysis was provided by Scientific Services laboratory in Cape Town, employing two-acid microwave digestion and ICP-OES techniques suitable for multi-element determination and following strict internal QAQC procedures inserting blanks and standards. Internal laboratory QAQC was also completed to include blanks, standards and duplicates.
The highest TiO2 grades were returned by nine consecutive samples in a single auger hole (A6), drilled to a dep
