MKANGO ANNOUNCES 60 PER CENT INCREASE IN MEASURED AND INDICATED RESOURCES, INCLUDING THE FIRST MEASURED RESOURCE FOR THE SONGWE HILL RARE EARTHS PROJECT IN MALAWI
London / Vancouver: February 4, 2019 - Mkango Resources Ltd. (AIM / TSXV: MKA) (the "Company" or "Mkango"), the rare earths exploration and development company focused on Malawi, is pleased to announce an updated mineral resource estimate for the Songwe Hill Rare Earths Project ("Songwe").
· 60% increase in total Measured and Indicated Resources to 21 million tonnes ("mt"), including first Measured Resource estimate for Songwe
· Majority of the previously delineated near surface Inferred Resource upgraded to either the Measured or Indicated categories
· Key objectives of 2018 drilling programme achieved, with the updated resource underpinning the ongoing feasibility study
· Approximately 95% of the Measured and Indicated Mineral Resource blocks are less than 160 metres ("m") below the surface of the hill indicating that the majority will be accessible by open pit mining
· Updated and enlarged resource underpins Mkango's strategy to be a long term, sustainable producer of neodymium, praseodymium, dysprosium and terbium used in permanent magnet motors for electric vehicles, wind turbines and other clean technologies
· Publication of the NI 43-101 Technical Report in relation to the resource update will trigger the next £7m milestone investment from Talaxis to fund completion of the feasibility study

William Dawes, Chief Executive of Mkango stated: "All the objectives for the 2018 drill programme have been achieved and we are very pleased to announce this increased resource at Songwe. This provides a solid platform for completion of a revised mine plan to be incorporated into the feasibility study. Based on the larger Measured and Indicated Resource, the feasibility study will evaluate opportunities to include more tonnes into the mine plan, expand operations, extend the mine life, reduce the strip ratio and therefore reduce mining costs."
The updated base case Mineral Resource Estimate equates to a 60% increase in the Measured and Indicated Resource tonnage and a 48% increase in the Inferred Resource tonnages versus the base case 2012 Mineral Resource Estimate, which formed the basis for the 2015 pre-feasibility study. The Mineral Resource is open at depth. The combined Measured and Indicated Mineral Resource Estimate, totaling 21mt grading 1.41% TREO, will form the basis of the updated mine plan for the ongoing feasibility study, which will evaluate a bulk tonnage, open pit mining operation focused on broad zones of near surface and outcropping rare earths mineralisation. The updated resource supersedes the 2012 Mineral Resource Estimate, and therefore renders the mining and economic information in 2015 pre-feasibility study obsolete. Updated mining and economic information will be generated as part of the ongoing feasibility study based on the new resource.
The Measured Mineral Resource Estimate comprises 42% of the combined Measured and Indicated Mineral Resource Estimate indicating a substantial increase in geological confidence to support the completion of the Feasibility Study.
The majority of the previously delineated near surface Inferred Mineral Resource Estimate has been upgraded to either the Measured or Indicated categories, achieving a key objective of the 2018 drill programme. Approximately 95% of the Measured and Indicated Mineral Resource Blocks are at a depth of less than 160m below the surface of the hill indicating that the majority will be accessible by open pit mining.
Bulk samples for pilot metallurgical test work totaling approximately 60 tonnes have been selected from areas within the Measured and Indicated Mineral Resource Estimates and a public awareness campaign to communicate progress of the project and explain the bulk sampling programme is underway in Malawi. Pilot testing will commence following export of the bulk sample and completion of ongoing metallurgical optimisation.
Mineral Resource Estimate
The Mineral Resource Estimate was independently prepared by The MSA Group of South Africa ("MSA"). Jeremy Witley Pr. Sci Nat. (the Qualified Person (QP) for the Mineral Resource Estimate) of MSA in collaboration and agreement with Dr. Scott Swinden, PGeo, the QP for the Exploration Information, has currently identified 1.0% TREO as an appropriate cut-off grade for the current Mineral Resource Estimate. This will be further refined over the course of the ongoing feasibility study. The Mineral Resource Estimates at different cut-off grades are illustrated in the table below.

1 Mineral resources are not mineral reserves and do not have demonstrated economic viability
The mineral resource has been drilled to a maximum depth of 355 m below the surface of Songwe Hill and is based on three phases of diamond drilling completed by Mkango in 2011, 2012 and 2018 totaling approximately 17,800 m in 125 drill holes. 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 mineral resource forms an irregular, roughly circular surface expression with a diameter of approximately 450 m. The maximum depth of the Inferred Mineral Resource is 390 m below surface, with the Measured and Indicated Mineral Resource occurring to a maximum depth of 200 m, paralleling the topographic surface of the hill and surrounding plain. The majority of the Measured and Indicated Mineral Resource occurs to a depth of approximately 160 m.
Geological domains, comprising Carbonatite, Mixed (altered and brecciated Carbonatite and Fenite) and Fenite dominant rock types, were used to guide the mineral resource evaluation. The Carbonatite dominant domain generally comprises a higher proportion of elevated TREO grade mineralisation than the Fenite dominant domain.
Key assumptions, parameters and methods used to estimate the Mineral Resources
· The drillhole intersections were used to estimate proportions of carbonatite (defined for this estimate as >15% Ca) and non-carbonatite for each cell in a three dimensional block model by means of indicator kriging. TREO values and density were estimated for carbonatite and non-carbonatite separately for the entire model using ordinary kriging. The final grade for the block was derived by multiplying the estimated proportion of carbonatite and non-carbonatite in the block by the estimated grade of carbonatite and non-carbonatite;
· The estimation block model cells are 20 mN by 20 mE by 5 mRL. The block models comprise sub-celled block dimensions of 5 mN x 5 mE x variable RL to closely fit the topography;
· No capping or cutting to limit any input grade data was undertaken as part of the mineral resource estimation, extreme outlier grades not being a feature of this deposit;
· Datamine Studio RM was the modelling package; and
· The mineral resource was classified as Measured, Indicated and Inferred based on the degree of geological certainty and drillhole density, supported by confidence parameter outputs from kriging (Kriging Efficiency and Slope of Regression). In general, the Mineral Resource was classified as Measured where it occurs within a 30 m by 30 m drillhole grid, Indicated where the Mineral Resource occurs within a drillhole spacing of closer than 50 m by 50 m. Inferred Mineral Resources were declared within the more sparsely drilled areas and extrapolation from the closest drillhole was limited to 50 m.

About Mkango Resources Limited
Mkango's primary business is 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". The Company holds interests in three exclusive prospecting licenses in Malawi: the Phalombe licence, the Thambani licence and the Chimimbe Hill licence.
The main exploration target in the 80% held Phalombe licence is the Songwe Hill rare earths deposit. This 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 and a Feasibility Study is currently underway, the initial phases of which included a 10,900 metre drilling programme and updated mineral resource estimate.
Under the terms of an agreement with Talaxis, Talaxis will fully fund the Feasibility Study for Songwe by investing £12 million for a 49% interest in the project (via Mkango subsidiary Lancaster Exploration Ltd). Talaxis will also have the option to acquire a further 26% interest by arranging funding for project development including funding the equity component thereof. If Talaxis exercises its option, Mkango will retain a 25% interest, free carried to production. To-date, Talaxis has invested £5 million, which has funded the initial phases of the Feasibility Study, for a 20% interest in the project, with Mkango holding 80%.
By investing a further £2 million, Talaxis will acquire a 49% interest in Maginito Ltd, a new subsidiary of Mkango focused on neodymium alloy powders, magnets and other technologies. This includes the collaboration with Metalysis Ltd announced in September 2017, which is focused on advanced alloys using neodymium or praseodymium with other elements for permanent magnet manufacturing. Permanent magnets are critical materials for most electric vehicles, direct drive wind turbines and many other high growth applications. Neodymium is a key rare earth component at Songwe. To date, Talaxis has invested £1 million for a 24.5% interest in Maginito with Mkango holding 75.5%.
The main exploration targets in Mkango's remaining two 100% held licences are, in the Thambani licence, uranium, niobium, tantalum and zircon and, in the Chimimbe Hill licence, nickel and cobalt.
