- NI 43-101 technical report filed, entitled NI 43-101 Technical Report and Mineral Resource Estimate for the Songwe Hill Rare Earth Element (REE) Project, Phalombe District, Republic of Malawi, and available on www.sedar.com
- The in-situ Indicated and Inferred mineral resource estimates at the chosen base case cut-off grade of 1.0% TREO represent a major milestone in the development of the project
- Substantial tonnages at a higher grade are also generated at a higher cut-off grade of 1.5% TREO
- The mineralized zones are untested at depths greater than 350 m below the surface of Songwe Hill and are open laterally to the northeast and southwest, with additional regional exploration potential
- The Indicated component comprises approximately 41.5% of the mineral resource and 45.4% of the estimated contained TREO at a 1.0% TREO cut-off grade, and, following the results of ongoing metallurgical studies, it may form the initial basis for commencement of a pre-feasibility study
- Heavy rare earths as a percentage of total rare earths are 7.1% and 7.4% for Indicated and Inferred mineral resource estimates, respectively, at a 1.0% TREO cut-off grade
Mineral Resource Estimate
The Report was independently prepared by The MSA Group of South Africa (“MSA”) and Dr. Scott Swinden of Swinden Geoscience Consultants Ltd, the “Qualified Person” (QP), who together have currently identifed 1.0% TREO as an appropriate base case cut-off grade for the mineral resource estimate. This will be further investigated on completion of metallurgical test work. The In-situ mineral resource estimates at different cut-off grades are illustrated in Table 1.

1 Mineral resources which are not mineral reserves do not have demonstrated economic viability
The estimated mineral resource has been traced in drill holes to a maximum depth of 350 m below the surface of Songwe Hill and is based on the two phases of diamond drilling completed by Mkango in 2011 and 2012 totalling approximately 6,850 m. The vast majority of the Indicated mineral resource blocks (at a 1% TREO cut-off, 9.1 mt of carbonatite, 0.67 mt of mixed and 1.04 mt of fenite) are at depths of less than 200 m below the surface of the hill. The areas drilled to date are in an elevated position on the northern slopes of Songwe Hill, which rises approximately 230 m above the surrounding plain. The approximate dimensions of the mineral resource estimate are 400 m aligned northeast by 230 m aligned northwest and to a depth of 350 m below and paralleling the topographic surface of the hill and surrounding plain.
Higher grade areas occur at various locations within the mineral resource, including at or close to surface, particularly in the north eastern part of the carbonatite domain. The mineralisation is not constrained by drilling at depth and laterally to both the northeast and southwest.
Geological domains, comprising either carbonatite or fenite dominant rock types, were used to guide the mineral resource estimate. Where the carbonatite and fenite lithologies were inseparable, a mixed domain was created.
The carbonatite dominant domain generally comprises a higher proportion of elevated TREO grade mineralisation than the fenite dominant domain. This results in a higher proportion of the mineralisation in this domain being reported above the 1% TREO cut off, albeit at a similar average grade to the other domains, as illustrated in Table 2.
The carbonatite domain is dominant at Songwe, comprising 84% of the Indicated and 46% of the Inferred mineral resources.
A schematic geological map illustrating the location of the drill holes will shortly be made available on the Company’s website (www.mkango.ca).
The individual REO data and ratios as presented in Tables 2, 3, 4 and 5 were derived from lengthweighted averages of the drill hole data. Heavy rare earths, as defined here, comprise europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and yttrium. These include the most highly priced of the more commonly traded rare earths, europium, terbium and dysprosium.
The overall weighted average proportion of heavy rare earths as a percentage of total rare earths for Indicated and Inferred resource estimates at 1.0% TREO cut-off grade is 7.1% and 7.4% respectively. The heavy rare earths vary with cut-off grade both in terms of absolute values and relative proportions. As TREO grade decreases, relative proportions of heavy rare earths increases (at 0.5% TREO cut-off grade, the HREO proportion is 7.7% and 8.2% for Indicated and Inferred categories, respectively) and the reverse is also true (at 1.5% TREO cut-off grade, the HREO proportion is 6.1% and 5.8% for Indicated and Inferred categories, respectively).
Apart from the proportion of heavy rare earths, a further measure of the potential value is the proportions of critical rare earths. The US Department of Energy has highlighted neodymium, dysprosium, europium, terbium and yttrium as being “critical” rare earths in terms of their importance to the clean energy economy and risk of supply disruption. Of these, dysprosium, europium, terbium and yttrium are heavy rare earths and are also reflected in the heavy rare earth ratio. Neodymium (Nd) is a light rare earth, principally used in the production of high strength permanent magnets.
The Songwe Hill mineral resource has an estimated weighted average grade of 2,665 ppm Nd2O3 and 2,240 ppm Nd2O3 in the Indicated and Inferred categories at 1.0% TREO cut-off grade, respectively. This equates to a weighted average proportion of Nd2O3 as a percentage of total rare earth oxides for Indicated and Inferred categories of 16.5% and 16.3%, respectively, as derived from Table 2.
Metallurgical Scoping Test Work
Metallurgical scoping work at Mintek in South Africa is ongoing, comprising flotation test work and leach tests. The current flotation test work is focused on a similar reagent regime to that used previously at the Mountain Pass mine and variations thereof. Further reagent regimes and conditions will continue to be tested. Rare earth mineralogy at Songwe is well understood, comprising predominantly synchysite and apatite.

1 Mineral resources which are not mineral reserves do not have demonstrated economic viability
Key assumptions, parameters and methods used to estimate the Mineral Resources
- wireframing of the three lithological units was based on surface geological mapping extended to
depth using the drillhole intersection data;
- TREO, HREO, Th and U grades as well as Density were determined using Ordinary Kriging
interpolation into individual 3-Dimensional block models constrained by the respective
lithological wireframes;
- the lithological block models comprised sub-celled block dimensions of 5 m x 5 m x 5 m.
- the lithology wireframes and block models were truncated to the topographic surface;
- no capping or cutting to limit any input grade data was undertaken as part of the mineral
resource estimation;
- Datamine Studio 3 was the modelling package; and
- mineral resources were classified as either Indicated or Inferred following an assessment of the grade and geological continuity exhibited by the data.
Scientific and technical information, including data verification, contained in this release has been approved and verified by Dr. Scott Swinden of Swinden Geoscience Consultants Ltd, who is a “Qualified Person” in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects.

The Songwe Hill Rare Earth Project
The Songwe Hill rare earth project is located within a 100% owned exclusive prospecting licence covering an area of 1,283 km2 in southeast Malawi (the "Phalombe Licence"). Songwe is accessible by road from Zomba, the former capital, and Blantyre, the principal commercial town of Malawi. Total travel time from Zomba is approximately 2 hours, which will reduce as infrastructure continues to be upgraded in the area.
Mkango Resources Ltd.
Mkango's primary business is the exploration for rare earth elements and associated minerals in the Republic of Malawi. It holds, through its wholly owned subsidiary Lancaster, a 100% interest in two exclusive prospecting licenses covering a combined area of 1,751 km² in southern Malawi. The main exploration target is the Songwe Hill rare earth deposit, which features carbonatite hosted rare earth mineralisation and was subject to previous exploration in the late 1980s.
The Corporation's corporate strategy is to further delineate the rare earth mineralisation at Songwe Hill and secure additional rare earth element and other mineral opportunities in Malawi and elsewhere in Africa.
