and expansion studies for the tier one Kamoa-Kakula Copper Project

on September 8, 2020

Ivanhoe plans to host an Investor Day on September 10, 2020,

to discuss the new studies and progress being made to bring the

project’s Phase 1 Kakula Mine to production

TORONTO, CANADA – Ivanhoe Mines (TSX: IVN; OTCQX:IVPAF) announced today that

on September 8, 2020, it plans to issue the independent definitive feasibility study for

the development of the 6 million-tonne-per-annum (Mtpa) Kakula Mine. The company

also will issue a pre-feasibility study, including mining 1.6 Mtpa from the nearby

Kansoko Mine, to take full advantage of an expanded plant capacity of 7.6 Mtpa at

Kakula. In addition, the company will issue an updated, expanded preliminary economic

assessment for the overall development plan of up to 19 Mtpa for all of the copper

discoveries made to date at the Kamoa-Kakula Project, in the Democratic Republic of

Congo (DRC).

The new definitive feasibility study, pre-feasibility study and updated, expanded

preliminary economic assessment will build on the outstanding results of the previous

studies announced in February 2019. The new definitive feasibility study will

incorporate the advancement of construction and development activities to date, and

the pre-feasibility study and expanded preliminary economic assessment will highlight

the potential to develop the Kamoa-Kakula Copper Project to a much larger scale, with a

significantly larger production capacity.

The Kakula 2020 definitive feasibility study, Kamoa-Kakula 2020 pre-feasibility study,

and Kamoa-Kakula 2020 preliminary economic assessment are being finalized by

leading industry consultants OreWin Pty Ltd. of Adelaide, Australia; DRA Global of

Johannesburg, South Africa; Stantec Consulting International LLC of Arizona, USA;

SRK Consulting Inc. of Johannesburg, South Africa; KGHM Cuprum R&D Centre Ltd. of

Wroclaw, Poland; and Wood plc of Reno, USA.

On September 10, 2020, Ivanhoe plans to host an inaugural virtual Investor Day to

discuss the findings of the independent engineering studies, including various options

under consideration to accelerate the planned expansions at the project. The Investor

Day will include a virtual site tour of the Kamoa-Kakula Project, as well as remarks from

Ivanhoe’s Co-Chairs Robert Friedland and Yufeng “Miles” Sun; the company’s

2

President and CFO, Marna Cloete; and members of the company’s corporate

development and technical teams. It also will have a question and answer session.

Webcast and dial-in information for the Investor Day, as well as a detailed agenda, will

be provided at a later date.

Ivanhoe also plans to provide its regular monthly update of construction and

development progress at the Kakula and Kansoko mines during the first week of

September.

The Kamoa-Kakula Copper Project is a joint venture between Ivanhoe Mines (39.6%),

Zijin Mining Group (39.6%), Crystal River Global Limited (0.8%) and the DRC

government (20%).

gold discovery in South Africa; and the extensive redevelopment and upgrading of the

historic Kipushi zinc-copper-germanium-silver mine, also in the DRC. Kamoa-Kakula
