Mkango Identifies New Zones of High Grade Uranium, Tantalum and Niobium at Thambani

May 24, 2017

Calgary, Alberta: May 24 2017 - Mkango Resources Ltd. (TSXV / AIM: MKA) (the "Corporation" or "Mkango"), announces results from recent sampling at the Thambani Project in southern Malawi:

  • Assay results from 85 rock grab samples returned high grade uranium, tantalum and niobium values, ranging up to 3.3 % U3O8, 1.9 % Ta2O5 and 6.0 % Nb2O5. 35 of the samples graded above 500ppm U3O8 and 24 graded above 1,000ppm U3O8. Results associated with the twenty best U3O8 assays are summarised in the table below.
  • The main objectives of the programme were to confirm previously identified high grade mineralisation at the Little Ngona target, ground-truth new geophysical targets and complete further reconnaissance sampling along the East and West Ridges.
  • New areas of high grade uranium, tantalum and niobium mineralisation were identified at the foot of the West Ridge and on the East Ridge. Most significantly, a radiometric high at the foot of the West Ridge yielded two of four highest grade samples of this phase of exploration.


Alexander Lemon, President of Mkango, said: "These results further support Thambani's exploration potential. Not only are the uranium results highly encouraging, but the equally positive tantalum and niobium results support that Thambani has significant multi-commodity potential."

Sampling was primarily focused on zones of anomalous uranium and associated niobium and tantalum targets across the Thambani Massif, a nepheline-bearing syenite gneiss which dominates the north-eastern part of the licence. Grab samples are selective samples and are not necessarily representative of the mineralization hosted on the property. The average grades for the 85 samples were 1,892 ppm U3O8, 1,029 ppm Ta2Oand 4,562 ppm Nb2O5. The median grades for the 85 samples were 343 ppm U3O8, 222 ppm Ta2Oand 958 ppm Nb2O5. The ranges of grades for the 85 samples were 1 - 32,590 ppm U3O8, 2 - 19,029 ppm Ta2Oand 0 - 60,055 ppm Nb2O5.

Mkango is currently evaluating strategic options for Thambani, including opportunities to joint venture or spin-off the project, and other potential avenues to create value.

Thambani Project

Mkango's exploration activities to date include acquisition of Landsat7 and ASTER satellite imagery for the licence area, interpretation of airborne geophysical data, systematic ground radiometric surveys, reconnaissance geological mapping and litho-geochemical sampling programmes. The work has identified a number of potential uranium and associated niobium-tantalum targets over the Thambani Massif, which is mainly composed of nepheline-bearing syenite gneiss, forming two prominent ridges known as Thambani East Ridge and West Ridge.

Radiometric surveys revealed two distinct uranium anomalies occurring across the Thambani East and West Ridges: a strong uranium anomaly, measuring approximately 3 kilometres ("km") by 1.5 km, occurs along the length of the Thambani East ridge, with a north-south trend, and a second NW-trending uranium anomaly, measuring approximately 1.5 km by 0.4 km, occurring along the foot of the West Ridge coincident with the western contact of the nepheline-bearing syenite body with granodioritic augen gneiss.

Sample preparation and analytical work for the sampling programme is being provided by Intertek-Genalysis Laboratories (Johannesburg, South Africa and Perth, Australia) employing assay methods suitable for the analysis of uranium, niobium and tantalum. Mkango inserted its own blanks and standards into the sample stream, and internal laboratory QAQC was also completed to include blanks, standards and duplicates.

About Mkango Resources Ltd.

Mkango's primary business is the exploration for rare earth elements and associated minerals in the Republic of Malawi, a country whose hospitable people have earned it a reputation as "the warm heart of Africa". Mkango holds, through its wholly owned subsidiary Lancaster Exploration Limited, a 100% interest in two exclusive prospecting licences in southern Malawi, the Phalombe licence and the Thambani licence.

The main exploration target in the Phalombe licence is the Songwe Hill rare earths' deposit, which features carbonatite hosted rare earth mineralisation and was subject to previous exploration in the late 1980s. Mkango completed an updated Pre-feasibility Study for the project in November 2015. Mkango's strategy for Songwe is to further optimise the project with a view to maximising efficiency and reducing costs, thereby providing a strong platform for entering into partnerships, marketing and offtake arrangements. In December 2016, Mkango entered into an agreement with Noble Resources International to collaborate in the rare earths sector. In March 2017, Mkango entered into a MOU with Metalysis Limited to jointly research, develop and commercialise novel rare earth metal alloys for use in three-dimensional (3D) printed permanent magnets.

The main exploration targets in the Thambani licence are uranium, niobium, tantalum and other associated minerals.
