Ivanhoe Mines announced that it are two distinct discoveries adjacent to the Kamoa-Kakula Copper Complex and continue Ivanhoe's distinguished track record of making greenfield discoveries in this uniquely endowed geological terrain. The two deposits occur within the 2,407-square-kilometre Western Foreland Exploration Project, which lies adjacent to the 400-square-kilometre Kamoa-Kakula copper Complex in the Democratic Republic of Congo (DRC). The theory was proven to be correct, as team of visionary geoscientists discovered Kamoa in 2008, followed by the monumental Kakula discovery in 2016.

In little over five years, Kakula went from drill core samples to one of the five largest copper mines in the world, with by far the highest grade, due to the hard work of outstanding project and operations teams. The Mineral Resource estimate is based on the results from approximately 50,000 metres of drilling in 148 holes. An additional 20 holes totaling more than 2,800 metres have been completed since the closure of the database for resource estimation purposes. Following the closure of the database for resources estimation, further drilling was completed to test shallow mineralization and to join the two Inferred zones.

The Mineral Resource estimate isbased on the results from approximately 13,000 metres of drilling in 35 holes. An additional four holes totaling more than 1,650 metres have been completed since the closing of the database for resource estimation purpose. Although most drill rigs on the Western Foreland Exploration Project are targeting other promising exploration targets during the favorable dry season, one drill rig tested the northern extension to the mineralization at Kiala as well as testing shallow targets on the periphery of domes west of the current Mineral Resource area through the end of September.

Both of the Makoko and Kiala Indicated Mineral Resource estimates are defined where the drill-hole spacing approximates a 400 to 600-metre grid. Additional drilling to expand and join the two separate areas of Inferred Resource at Makoko has been completed. This incorporates the estimated Mineral Resource at Kamoa-Kakula with the Makoko Mineral Resource and Kiala Mineral Resource declared in this release.

Kamoa-Kakula Mineral Resource at a 1.0% cut-off grade. During the quarter, the number of contractor diamond drill rigs increased to seven, in addition to the Ivanhoe Landcruiser diamond drill rig. Other disclosures of a scientific or technical nature at the Western Foreland Exploration Project in this news release have been reviewed and approved by George Gilchrist, who is considered, by virtue of his education, experience and professional association, a Qualified Person under the terms of NI 43-101.

The technical report does not contain information regarding the mineral resources disclosed in this news release regarding the Western Foreland Exploration Project. Ivanhoe Mines also is exploring for new copper discoveries across its circa 2,400km2 of 80-100% owned exploration licences in the Western Foreland, located adjacent to, or in close proximity to, the Kamoa-Kakul Copper Complex in the DRC.
