Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF) Reports Unprecedented 22.3-Metre Intersection of 13.05% Copper in a Shallow, Flat-Lying Discovery at the Kamoa North Copper Exploration Area on the Kamoa-Kakula Mining Licence

Drill hole DD1450 intersection includes grades of up to 40% copper and is within 190 metres of surface

DD1450 is the thickest, highest-grade copper intersection drilled to date at Kamoa-Kakula, highlighting the potential for significant additional resource expansion

 

Kolwezi, Democratic Republic of Congo - January 30, 2019 (Newsfile Corp.) (Investorideas.com Newswire) Robert Friedland and Yufeng "Miles" Sun, Co-Chairmen of Ivanhoe Mines (TSX: IVN) (OTCQX: IVPAF), announced today that exploration hole DD1450 drilled at the Kamoa North prospect area, on the 397-square-kilometre Kamoa-Kakula mining licence, has intersected 13.05% copper over 22.3 metres (true thickness), at a 2% copper cut-off grade, in a remarkably-thick, flat-lying, ultra-high-grade deposit beginning at a depth of only 190 metres below surface.

Drill hole DD1450 includes multiple, one-metre intersections with copper grades higher than 20% copper, including a 40%-copper intercept (see Figure 1 for a detailed mineralization profile).

At a cut-off of 5% copper, DD1450's intersection is 15.92% copper over 16.8 metres (true thickness). Using a lower cut-off grade of 1% copper, the intersection is 10.29% copper over 29.4 metres (true thickness), beginning at a depth of only 190 metres below surface.

The new drill hole, DD1450, is located approximately 18 kilometres north of the Kamoa-Kakula Project's planned initial mine at the Kakula Deposit and approximately eight kilometres north of Kamoa's Kansoko Mine development (see Figure 2).

DD1450 is one of 22 recently-drilled holes at Kamoa North. A complete list of assay results, at various cut-off grades, from the recent holes is in Table 1 on page 11.

DD1450 is further evidence of the emergence of Kamoa North as a prospective new, shallow mining area on the Kamoa-Kakula mining licence. Previous drill holes in the area had delineated zones of shallow, flat-lying, thick, high-grade copper, but DD1450 is the thickest, highest-grade copper intersection since drilling commenced on the Kamoa-Kakula Project more than a decade ago.

"DD1450 exceeds anything previously encountered in all of our years of delineating resources on the project," said Mr. Friedland. "The flat-lying, 10% copper intersection in hole DD1450 is almost 30 metres, or 100-feet thick - essentially equivalent to a 10-storey building - and the high-grade copper is less than 200 metres below surface. If we apply a 5% copper cut-off to the intersection, the grade increases to approximately 16% copper and it's still almost 17 metres thick, or approximately 56 feet.

"Hole DD1450 is three times richer on a copper-grade-times-thickness measurement than any previous hole drilled at Kamoa-Kakula. Now our immediate exploration focus is to find more of this near-surface, bonanza-grade ore."

"On behalf of everyone at Ivanhoe Mines, I want to wish our Chinese partners at Kamoa-Kakula and our Congolese stakeholders a happy Year of the Pig," Mr. Friedland added.

Close-spaced drilling is underway in the vicinity of DD1450 with the intention of better understanding the controls and the orientation of the ultra-high-grade zone. Initial indications suggest growth faulting in the proximity of DD1450 may have played a part in enhancing fluid flow during the mineralizing process. The exceptional grade and thickness of the intersection means that even a zone of limited dimensions could prove extremely significant if targeted early from a future Kamoa North decline.

The tier-one Kamoa-Kakula Project is approximately 25 kilometres west of the mining centre of Kolwezi in the Democratic Republic of Congo (DRC). The project is a joint venture between Ivanhoe Mines, Zijin Mining and the DRC government.

An independent Mineral Resource estimate published in February 2018 established Kamoa-Kakula as the world's fourth-largest copper discovery. Kamoa-Kakula's copper grades are the highest, by a wide margin, of the world's top 10 copper deposits.

Kamoa North exploration success highlights the potential for significant resource expansion at Kamoa-Kakula and on the adjacent Western Foreland exploration licences that are 100%-owned by Ivanhoe Mines

The newly delineated copper corridors at Kamoa North occur on the western flank of the un-mineralized Kamoa Dome. The most significant corridor trends north and south for more than nine kilometres before swinging to the northwest and is projected to continue onto the adjacent Western Foreland exploration licences that are 100%-owned by Ivanhoe Mines. The second corridor trends west-southwest, away from the Kamoa Dome and toward the West Scarp Fault, over a distance of three to four kilometres.

The copper corridors are indicated with dashed and dotted lines in figures 3 and 4 (pages 6 and 7). The corridors are partly within the previously defined Inferred Mineral Resources, but the definition provided by additional drilling has allowed significantly increased continuity of grade to be established and then extended along strike into previously untested areas. The recognition of high-grade trends in areas previously tested by wider-spaced drilling reflects a growing understanding of the controls on mineralization at Kamoa-Kakula.

Mineralization thicknesses range from three metres up to 30 metres at a 1% copper cut-off. The mineralized horizon generally is in the region of 150 metres to 300 metres below surface, except on the west side of the West Scarp Fault, where it strikes roughly north-south and dips gently to the west at between five and 10 degrees.

Copper sulphide mineralization at Kamoa North tends to be bottom-loaded and shows typical downward zonation from chalcopyrite to bornite to chalcocite. Chalcopyrite dominates in the lower-grade intercepts and when mineralization extends into the overlying pyritic siltstone. Fine-grained bornite and chalcocite dominate in the highest-grade intersections.

The Kamoa North discovery area already is accessible by an all-season road that connects with the provincial road to Kolwezi and is close to the newly installed electricity line running from Kamoa North to the planned Kansoko and Kakula mines.

Range of mine-development options at Kamoa-Kakula under study

The pre-feasibility study (PFS) for the planned, initial six million-tonne-per-annum (Mtpa) Kakula Mine is expected to soon be completed and will be a key part of the new Kamoa-Kakula Integrated Development Plan. The PFS will provide more detailed information related to the project's economic assumptions and will incorporate results from detailed engineering and optimization work.

An updated Kamoa-Kakula Mineral Resource estimate, which will incorporate recent drilling results from the project, is being prepared as part of the Kamoa-Kakula Integrated Development Plan.

Ivanhoe and Zijin also are exploring potential options to expand future production. The 2017 PEA noted the potential for a 12 Mtpa scenario, to be achieved through the sequential development of both the Kakula and Kansoko mines. Based on subsequent discoveries, including Kakula West and Kamoa North, Ivanhoe and Zijin also are exploring the potential for expanding production to 18 Mtpa, and beyond.

Exploration is continuing to progress at Kamoa-Kakula and to the west, on Ivanhoe's 100%-owned exploration licences in the adjacent Western Foreland area, where drilling recently discovered a large, high-grade zone of copper at Makoko.

Ivanhoe believes this phased approach to building what ultimately could become one of the world's largest copper-mining complexes will provide an attractive combination of lower initial capital cost while maintaining key operating efficiencies and economies of scale.

The newly delineated, high-grade zones at Kamoa North are near surface and flat lying. Given this depth and dip, they could be amenable to traditional, non-fill room-and-pillar-style mining that is highly productive and economically efficient. The potential construction of additional shallow access declines in the Kamoa North area will be studied, which would expand the range of options presently being considered for the development of Kamoa-Kakula.

Both the Kakula Discovery and the earlier Kamoa Discovery continue to remain open for expansion.

The current, combined Kamoa-Kakula Indicated Mineral Resources total 1.34 billion tonnes grading 2.72% copper, containing 80.7 billion pounds of copper at a 1.0% copper cut-off grade and an approximate minimum thickness of 3.0 metres. At a higher, 1.5% copper cut-off grade and a minimum thickness of 3.0 metres, the combined Kamoa-Kakula Indicated Mineral Resources now total 1.03 billion tonnes grading 3.17% copper, containing 71.7 billion pounds of copper.

Kamoa-Kakula also has Inferred Mineral Resources of 315 million tonnes grading 1.87% copper, containing 13.0 billion pounds of copper at a 1.0% copper cut-off grade and an approximate minimum thickness of 3.0 metres. At a 1.5% copper cut-off grade and a minimum thickness of 3.0 metres, Kamoa-Kakula's Inferred Mineral Resources now total 183 million tonnes grading 2.31% copper, containing 9.3 billion pounds of copper.

Research by Wood Mackenzie also confirms that the Kamoa-Kakula Project is the world's largest, high-grade (>2.5% copper grade) copper deposit and the world's largest, undeveloped copper deposit, based on contained copper in the project's Measured and Indicated Mineral Resources.
