Hollywood, Florida – February 23, 2023 (Newsfile Corp.) (Investorideas.com Newswire) Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF) Executive Co-Chair Robert Friedland and President Marna Cloete, announced today ahead of the 32nd BMO Global Metals & Mining Conference an update on exploration activities at the company’s 90-100%-owned Western Foreland Exploration Project.
Ivanhoe Mines’ DRC exploration team is targeting high-grade Kamoa-Kakula-style copper mineralization across its 2,407-square-kilometre Western Foreland licence package, which lies adjacent to the 400-square-kilometre Kamoa-Kakula Copper Complex in the Democratic Republic of Congo (DRC). The Western Foreland licences cover the same geological setting as the neighbouring Kamoa-Kakula deposits.
Initial exploration activities on Ivanhoe’s Western Foreland licences began in July 2017. Given the frontier nature of the topography, activities started with the construction of critical infrastructure to provide access for exploration equipment. This included the construction of all-season access roads and bridges, as well as new camp facilities. To date, Ivanhoe has completed over 105 kilometres of new and refurbished, all-season access roads, including a 90-kilometre spine road running through the centre of the licences that provides access to all its licences in the southwest region of the Western Foreland.
In parallel, Ivanhoe has undertaken airborne and ground-based geophysical surveys, targeted regional air core and diamond drilling, and revisited previously acquired geophysical and geochemical data sets. Ivanhoe’s interpretative work to date has led to the definition of several promising exploration targets, including the discovery of the high-grade Makoko and Kiala copper discoveries.
The initial discovery of Makoko in 2018, situated approximately 20 kilometres west of the Kakula deposit, proved Ivanhoe’s exploration model for the geologic features controlling the high-grade copper mineralization in the region. Drilling to date at Makoko has defined a flat-lying, stratiform copper deposit that is geologically similar to the Kamoa and Kakula deposits. The second area of discovery in the Western Foreland was on the Kiala licence in early 2020, which adjoins the northern boundary of the Kamoa-Kakula mining licence. Kiala is the northern extension of the Kamoa Far North zone, which is located on the Kamoa-Kakula joint venture.

Regional drill campaigns and geophysical programs in 2022 continue to improve Western Foreland geological and basin models
During the 2022 exploration season, a total of 26,483 metres were drilled, including 4,633 metres of air core and 21,920 metres of diamond drilling.
The diamond drilling campaign was largely conducted on wide-spaced regional sections intended to improve the understanding of the geology and geometry of the underlying copper belt stratigraphy, which will be used to narrow down future targets.
Air core results, combined with the airborne gravity geophysical data, are used to define the basin limits and internal structures. Air core drilling is designed to collect samples from the underlying rocks that sit below the exotic Kalahari sands cover, which can be as much as 40 metres thick, for geochemistry and lithology identification. The air core program was shortened in 2022, as results from regional drilling lowered the prospectivity of planned target areas.
More detailed exploration activities took place in the Lupemba, Mushiji and Makoko areas (see Figure 2).

In the Lupemba area, in the southwest of the Western Foreland, a ground-gravity program was undertaken along with a large, 800-metre-spaced air core drilling grid.
In the Mushiji area, which is north of the Kamoa-Kakula Copper Complex, drilling was focused on defining the northern limit of the Roan Basin, which now appears to be restricted to the southern 15 kilometres of the permit. The 2023 exploration program will focus on the southern portion of the Mushiji area.
In the Makoko area, exploration focused on testing the six-kilometre western extension of the growth fault corridor that was previously identified by wide-spaced drill sections in 2021. The 2022 drill program consisted of step-out and in-fill drilling, totaling 8,000 metres in 41 holes. Continuity of mineralization was proven. These results will be incorporated into the Mineral Resource estimate for Makoko, planned for mid-year.
Ivanhoe to commence expansive 2023 copper exploration campaign on the greater Western Foreland licences
Ivanhoe’s initial 2023 exploration program includes approximately 70,000 metres of combined air core and diamond drilling, as well as ground-based geophysics and soil sampling programs, and additional access road construction. Field work will commence at the start of the 2023 dry season, which typically begins in April. The initial 2023 budget is approximately US$19 million, however this may be expanded based on program results.
Exploration activities in 2023 will continue to focus on the licence-wide collection of air core samples for geochemical testing, as well as the ongoing refinement of geophysical data interpretations to further improve internal geological and basin models.

Mineral Resource definition drilling at Makoko is planned to further define the extent and structure of mineralization, ahead of a planned maiden Mineral Resource estimate planned for mid-year. In addition, hydrogeological and geotechnical studies, as well as further metallurgical test work will be conducted.
Ivanhoe will continue to pursue new licence applications and also explore opportunities for joint ventures across the region in areas it considers prospective.
Ivanhoe to undertake maiden Mineral Resource estimates on Makoko and Kiala, followed by Preliminary Economic Assessment
Work is underway on a Mineral Resource estimate for the Makoko and Kiala targets, incorporating drill hole data acquired during 2022. The Mineral Resource estimate is expected to be released in mid-2023.
The Mineral Resource estimate will be followed by the commencement of a Preliminary Economic Assessment (PEA) for the development of these mining areas, which are currently 90%-owned by Ivanhoe.
Drilling at Makoko has defined a flat-lying stratiform copper deposit, similar in setting to the Kamoa and Kakula deposits. The mineralized zone at Makoko relates to an east-southeast trending growth fault structure and has now been tested over a strike length of approximately 11 kilometres. Recent drilling up-dip of the Makoko mineralized structure has intersected a second parallel zone of shallower mineralization. Both zones of mineralization deepen along strike from west to east.
The highest grade section of the Makoko deposit occurs between 400 and 800 metres in depth and coincides with the area of 200-metre spaced drilling as shown in Figure 3. Figure 4 shows a three-kilometre section along strike where the flat-lying, copper-rich zone is between 400 and 500 metres below the surface.
The Kiala area is considered prospective as there are two key ingredients to high-grade mineralization occuring in this area. This favourable combination is also responsible for the Bonanza-style grades in the Kamoa North area of the adjacent Kamoa-Kakula Copper Complex.
