KINSHASA, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX:
IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun are pleased to announce
that Ivanhoe Mines Energy DRC, a sister company of Kamoa Copper SA tasked with
delivering reliable, clean, renewable hydropower to the Kamoa-Kakula Copper Mine, has
signed a memorandum of understanding (MOU) in a public-private partnership with the
DRC’s state-owned power company La Société Nationale d'Electricité (SNEL) to
upgrade a major turbine (#5) in the existing Inga II hydropower facility on the Congo
River.
His Excellency Félix Tshisekedi, President of the Democratic Republic of the Congo,
commented on the significance of the public-private partnership to upgrade one of eight
turbines at the Inga II hydroelectric power station to produce clean, renewable
electricity to support Kamoa-Kakula’s expansion plans and provide reliable electricity to
local communities: “The Democratic Republic of the Congo is blessed with
2
extraordinary hydroelectric potential. It is imperative to develop this potential because
hydropower is clean, reliable and renewable. It is undoubtedly the most suitable type of
electricity to support our country’s long-term development priorities.”
“Partnerships such as the one between SNEL and Ivanhoe allow us to inject additional
capacity into our electrical grid and improve the living conditions of Congolese citizens
by increasing their access to electricity. At the same time, the additional power that will
be generated will allow Kamoa-Kakula to beneficiate its mining products in the DRC.
This will create additional revenue for the country, as well as employment opportunities
for our people. As the host country and as a shareholder of Kamoa Copper, the DRC
sees this local value creation as a strategic imperative," President Tshisekedi added.
Ben Munanga, Chairman of Kamoa Copper, remarked: “The bilateral cooperation
between Ivanhoe Mines Energy DRC and SNEL to secure reliable power for Kamoa-
Kakula is a win-win partnership and underscores the importance that the DRC
government places on the development of large-scale mining projects in the country.”
“This new power-supply agreement is an important step forward on our sustainability
journey as it will provide Kamoa-Kakula with priority access to a combined 240
megawatts of clean, renewable electricity from the upgraded turbines at Mwadingusha
and Inga II hydropower plants,” Mr. Munanga added.
Estimated 162 megawatts of hydropower expected to be generated by
upgrading Inga II’s turbine 5
The Inga II hydropower plant is located in the southwest of the DRC, on the Congo
River. The Congo River is the deepest river in the world and the second longest after
the Nile, with a flow rate second only to the Amazon’s. Measured along with the
Lualaba, the main tributary, the Congo River has a total length of 4,370 kilometres. It is
the only major river to cross the equator twice. The Congo River is unique in that it has
large rapids and waterfalls very close to the mouth while most rivers have these
features upstream. The rapids and waterfalls give the Congo River huge hydropower
potential. The Congo Basin covers an estimated total area of 3.7 million square
kilometres, approximately 13% of the entire African landmass.
Originally equipped between 1977 and 1982, Inga II has been running for approximately
40 years. Four of the eight turbines at Inga II have been refurbished. Turbine 5 is one of
the remaining four that are awaiting an upgrade. An estimated output of 162 megawatts
(MW) is expected to be unlocked by upgrading Inga II’s turbine 5, part of which will be
used to meet future power requirements of the Kamoa-Kakula Mine. The surplus power
produced from the upgraded turbine will be distributed on the national power grid to
increase access to electricity for the citizens of the DRC.
SNEL and Ivanhoe Mines Energy DRC plan to appoint Voith Hydro of Heidenheim,
Germany, a leading engineering group, as the contractor to lead the consortium of
3
equipment manufacturers for the turbine upgrade. For more than 80 years, Voith has
successfully constructed and modernized hydropower plants on the African continent,
and approximately 25% of currently installed turbine capacity in Africa has been
supplied by Voith. Voith also has successfully rehabilitated two turbine generators at
the adjoining Inga I hydropower plant, a project that was financed by the World Bank.
Detailed engineering and costing for the upgrading of Inga II’s turbine 5 is ongoing.
However, initial indications are that the upgrading can be accomplished at a
significantly reduced cost per megawatt generated compared to the upgrading of the
Mwadingusha plant.

Hydropower for sustainable development
Mr. Friedland said a long-term, sustainable supply of electricity is essential to Ivanhoe’s
vision to develop Kamoa-Kakula into one of the world’s largest copper projects and
doing it in an environmentally, ethically and socially responsible manner. As a
sustainable source of energy, hydropower can make a significant contribution to a
country’s economic and social development.
“Until now, a key limiting factor in expanding Kamoa-Kakula to its full potential has
been the availability of sufficient power. Given the project’s massive Indicated
Resources of approximately 1.4 billion tonnes grading 2.7% copper, at a 1% cut-off, and
the outstanding potential to find more high-grade copper, the new partnership with
SNEL on Inga II gives us a clear line of sight to realizing our vision of building Kamoa-
Kakula into the world’s largest, high-grade, green copper mine,” said Mr. Friedland.
“Our first public-private partnership with SNEL – the upgrading of the Mwadingusha
hydropower plant – has gone very well and we are pleased that facility will provide
clean hydro-generated electricity to local communities as well as to Kamoa-Kakula for
Phase 1 and Phase 2 production. The supply of reliable hydropower is critical to
Kamoa-Kakula achieving its goal of becoming the world's “greenest” copper mine and
be among the world's lowest greenhouse gas emitters per unit of copper produced.
“The signing of the MOU with SNEL for the upgrade of turbine 5 at Inga II is an
expedient, cost-effective way to deliver clean, reliable and renewable electricity to
Kamoa-Kakula for the project’s planned expansions and the project’s own smelter. Our
preference always has been to work with SNEL to upgrade existing hydro facilities,
providing a shared benefit for as many people as possible.
“We are fortunate to be operating in the DRC, which is blessed with incredible
hydropower potential. Hydropower, being clean, reliable and sustainable, is the best
energy solution to support our long-term development priorities as we continue to look
for ways to reduce our impact on the environment, provide meaningful and long-lasting
benefits to the communities in which we operate, and produce the copper the world
urgently requires.”
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 Government of
the Democratic Republic of Congo (20%).

Kamoa-Kakula was connected to the national electrical grid, providing access to the
Inga-Kolwezi high-voltage direct current power line, through the New Western Dispatch
substation in Kolwezi. Kamoa-Kakula’s main 220-kV substation was energized with grid

Upgrading of the 78-MW Mwadingusha hydropower plant nearing
completion; new fly-over video showcases latest advancements
Upgrading of the six new turbines at the Mwadingusha hydropower plant, the first
public-private partnership between Ivanhoe Mines Energy DRC and SNEL, is nearing
completion and is expected to soon deliver approximately 78 MW of electricity to the
national electrical grid, to provide power for Kamoa-Kakula’s initial two phases of
production to 7.6 million tonnes per annum (Mtpa).
Three of the six new turbines at the Mwadingusha hydropower plant now have been
synchronized to the national electrical grid, with each generating unit producing
approximately 13 MW of electricity. The completion and commissioning of the
hydropower plant’s remaining generating units, in sequence, is in progress.

associated infrastructure: https://vimeo.com/541351071
Supervision of the upgrading work at Mwadingusha is being conducted by Stucky Ltd.
of Renens, Switzerland. The advance payments made by Ivanhoe Mines Energy DRC to
fund the upgrading work will be recovered by Kamoa-Kakula through a retention of a
percentage on monthly electricity consumption bills.
