· Assays of carbonatite dyke samples return grades of up to 5.92% TREO (Total Rare Earth oxides) median 2.96%.

· Mapping and geophysics results confirm that the major geological features of Nkalonje Hill (“Nkalonje”) are those of an alkali silicate-carbonatite intrusive complex, similar to Songwe Hill.

· Geophysics has identified a primary shallow drilling target beneath exposed mineralised dykes and a secondary deeper drilling target.

London / Vancouver: April 7 , 2022 – Mkango Resources Ltd. (AIM/TSX-V: MKA) (the “Company” or “Mkango”) is pleased to provide an update on the exploration programme at the Nkalonje Hill Rare Earths Project, 14 km from Mkango’s Songwe Hill Rare Earths development project (see Figure 1). Mapping, sampling and ground geophysical data were obtained at Nkalonje in Q4 2021, following up on encouraging historical regional geophysical data.

Alexander Lemon, President of Mkango, commented:

“We are extremely encouraged by the recent exploration results for the Nkalonje Hill Rare Earths project. The targets generated from the mapping and geophysics data are exciting indicators of the potential for further mineralisation at depth. The similarities between Nkalonje and Songwe Hill, and the high TREO grades from the assay results, demonstrate a strong case for further investigation. In the long term, the close proximity of Nkalonje to Songwe provides a good potential source of additional REE feedstock for processing at Songwe.”

Nkalonje Hill Rare Earths Project

· Nkalonje is located 23 km by road (14 km straight line) north-west of Mkango’s Songwe Hill Rare Earths Project, within the Company’s Phalombe Licences. The project is approximately 95 km by road from the commercial centre of Blantyre, which has an international airport and a railhead. Paved roads run from Blantyre to within 19 km of Nkalonje.

· Nkalonje is underlain by an alkali silicate-carbonatite intrusive complex geologically similar to Songwe Hill, comprising two connected hills underlain by fenite, nepheline syenite and breccia (see map below). Regional geophysical data from the World Bank funded programme in 2016 demonstrates that Nkalonje is marked by a magnetic low and thorium high. Thorium radiometrics are known as a highly effective tool for rare earths exploration and the Songwe Hill carbonatite is also characterised by a thorium radiometric anomaly, identified through previous geophysical surveys.

· The fenites on Nkalonje are intruded by carbonatite veins and dykes that are locally enriched in rare earth elements, suggesting potential for a larger mineralised carbonatite body below surface.

Exploration results

Geological mapping and geophysics data for Nkalonje confirms the presence of previously mapped nepheline syenite, breccia and carbonatite (see Figure 2).

· The ground geophysics data support the geological interpretation of a ring complex structure, as seen at Songwe, and at other carbonatite vents in Malawi. The overall diameter of this structure is approximately 1.7 km and comprises an outer ring of nepheline syenite and a central vent of breccia.

· The breccia body is approximately 900 m in diameter and comparable in lateral extent to Songwe Hill.

· Mapping to date has identified eight carbonatite dykes reaching 4 m in width and traceable at surface up to 90 m along strike.

· Two different carbonatite types are noted at Nkalonje: (1) calcite carbonatite, and, (2) a banded ferroan calcite carbonatite.

· Assay results for 12 calcite carbonatite and 17 ferroan calcite carbonatite grab samples returned TREO grades of up to 5.92%, with a median value of 2.96% in the ferroan calcite carbonatite, suggesting concentration of the rare earth elements (“REE”) in the more evolved carbonatite phases.

· The geophysical characteristics of the central breccia vent include a low magnetic response, low density and high conductivity. However, it also includes a central gravity anomaly extending from the surface to approximately 300 m depth. This feature is tentatively interpreted as a shallow body of carbonatite, which fits the observed lithologies present at Nkalonje, and the conceptual structure of the hill.

Exploration targets at Nkalonje

Based on interpretation of the recent data, the Company has identified two drilling targets at Nkalonje (see Figure 2 below).

· Target 1 is centred on known mineralisation around the carbonatite dykes. Further mineralisation at depth is interpreted from Induced Polarity (“IP”) and Natural Source Audio Magneto-Telluric (“NSAMT”) geophysical anomalies which present a series of potential shallow drill targets extending down-dip of the exposed dykes.

· Target 2 is a conceptual target based on geophysical anomalies which consist of a surface radiometric anomaly (high Th), a gravity high and magnetitic low, with an IP anomaly at depth. The target is in a relatively eroded, poorly exposed part of the hill. These geophysical and geomorphological features fit with a conceptual model of a central carbonatite body, common to other carbonatite complexes, which the surface dykes suggest may potentially contain REE mineralisation.

Work plan

Planned work at Nkalonje consists of continued evaluation of the dykes at Target 1, including new sampling (including channel sampling where possible) in order to trace the grade of the dykes along strike. A soil/auger sampling and trenching programme is planned to ground truth the geophysical anomalies at Target 2.

Methods and Quality Control

Sample preparation and analytical work was provided by Intertek-Genalysis Laboratories (Johannesburg, South Africa, and Perth, Australia), employing ICP-MS techniques suitable for REE analyses and following strict internal laboratory QAQC procedures, inserting blanks, standards and duplicates, in addition to blanks and standards inserted by Mkango.

Ground geophysics data was acquired over the Nkalonje vent by Gregory Symons Geophysics (Namibia) in November-December 2021. Ground magnetic, radiometric and gravity data were collected over an area of 2.7 x 2.7 km, covering the hill and surrounding lake sediments, with magnetic and radiometric data collected at 50 m line spacing, and gravity data collected along selected lines at 100 m spacing. 3D inversions of the magnetic and gravity data were processed using VOXI Earth Modelling in Oasis Montaj software. The NSAMT data was acquired on two lines, bisecting the hill at 50 m station spacing, and the IP survey was carried out using a pole-dipole electrode spread on eight lines with a 50 m dipole spacing.
