NEWS RELEASE
EASTERN PLATINUM FILES UPDATED TECHNICAL REPORT ON THE CROCODILE RIVER MINE
May 20, 2022, Vancouver, British Columbia – Eastern Platinum Limited (“Eastplats” or the “Company”) is
pleased to announce that it has filed the “NI 43-101 Technical Report on the Crocodile River Mine (“CRM”),
North West Province, South Africa” (the “Report”) dated January 1, 2022 on SEDAR. The CRM is a
platinum group metal (“PGM”) mine located 70 km north-northwest of Johannesburg in the North West
Province and 7 km south of the town of Brits and situated on the western limb of the Bushveld Igneous
Complex in an area of known structural complexity, the Brits Graben. The current mine lease area includes
one operating mining section (the “Zandfontein Section”) and two development sections (the “Crocette
Section” and the “Kareespruit Section”, respectively).
The Report has been updated, in preparation of the re-start of underground mining at the Zandfontein
Section of CRM which was placed under care and maintenance in 2013. The resources and reserves
updates of the Report apply to each of the Zandfontein Section, the Crocette Section and the Kareespruit
Section.
In connection with the filings, the Company is pleased to provide a statement of the current resources and
reserves supported by the Report. Capitalized terms used and not otherwise defined in this news release
have the meaning ascribed to them by The Canadian Institute of Mining, Metallurgy and Petroleum.
Zandfontein underground (the project) M&I resource is 28Mt with 3.96Moz and a reserve of 14.58Mt
with 1.72Moz for the current project plan of 22 years.
The resources are effective as of January 1, 2022. The following table presents the Measured and Indicated
Mineral Resource for underground:

The Mineral Reserve estimate for the CRM underground operations as at January 1, 2022 is detailed in the
table below:

Notes:
1. The Mineral Reserve estimation includes only diluted Measured and Indicated Mineral Resources which have been
converted to Proved and Probable Mineral Reserves.
2. A portion of Inferred Mineral Resources are included in the LoM plan, as it is required to mine through Inferred portions to
access Measured and Indicated Mineral Resources. These Inferred Mineral Resources have, however, been excluded in
the Mineral Reserve estimation and in the economic analysis.
3. No Inferred Mineral Resources have been included in the Mineral Reserve estimation.
4. The Mineral Reserve estimation was completed using a 4E basket price of USD1,825/oz and exchange rate of 15.53
ZAR/USD.
5. An uneconomical tail of 133.34 kt at a 4E grade of 3.51 g/t, containing 15.06 koz has been excluded from the Mineral
Reserve estimate.
6. The Mineral Reserves are reported as total Mineral Reserves and are not attributed.
The Mineral Reserve estimate for the CRM TSF Re-mining operation as at January 1, 2022 is detailed in
the table below:
Mineral Reserve Tonnes 4E Grade 4E Content Cr?O? Content Cr?O? Grade
Category kt g/t kg koz kt %
Probable 7,570 1.10 8,345 268 1,371 18.12
Notes:
1. The Mineral Reserve estimation includes only diluted Measured and Indicated Mineral Resources which have been
converted to Probable Mineral Reserves.
2. No Inferred Mineral Resources have been included in the Mineral Reserve estimation.
3. The Mineral Reserve estimation was completed using a 4E basket price of USD2,305/oz, and calculated Chrome price
(as per offtake agreement) of USD106/t and exchange rate of 15.53 ZAR/USD.
4. Chrome ore produced from the re-mined tailings is sold on a cost-plus basis, considering the TSF remining costs,
processing cost and chrome logistics costs and an additional allowance for certain overheads.
5. The Mineral Reserve excludes PGMs and Chrome Oxide from the TSF already re-mined since December 2018.
6. The Mineral Reserves are reported as total Mineral Reserves and are not attributed.
Full details of the methodology used in the estimation of reserves and resources, along with details of the
mining operations at CRM are provided in the Report filed on SEDAR.
Based on the updated resources and reserves, the planned re-start project at the underground mine at
CRM will focus on the Zandfontein Section (the “Planned Project”).
This is a robust project based on a hybrid mining method that was selected from the trade-off study
conducted in 2021. This mining method was selected considering the geological complexity of the
Zandfontein orebody and the requirements for the selection of a suitable, technically and economically
viable mining method. The hybrid mining method is well suited to the orebody and allows for minimum off-
reef development. The mine plan is practical and a production ramp up to steady state production volumes
has been planned.
The study was conducted on a “standalone underground” operation, as well as an “including the remining
and processing of the Tailings Storage Facility (“TSF”)” operation.
The Planned Project Highlights (all amounts in USD unless specified)
Net Present Value (“NPV”) of approximately $188.0 million excluding the TSF and $202.0 million including
the TSF, based on the following parameters:
o at 11.87% discount rate using a life of mine (“LoM”) long term 4E PGM basket price and
calculated chrome price as per the offtake agreement;
o the exchange rate utilized for the conversion to USD is R15.53; and
o LoM: 1.51 million 4E oz of commercial production over 22 years.
The following table presents a range of values based on various discount rates:

• Non-sustaining capital costs of $21 million, which includes a 15% contingency applied to capital
expenditure estimates with a Total All-In Costs of $1,537 per 4E oz with a contingency of 20%
applied to mining operating costs, and 10% applied to the processing and other costs, in line with
estimate accuracies.
• Payback period of 2.0 years including the TSF.
Diana Hu, President, Chief Executive Officer, and Director of Eastplats commented, “Now the Company
will embark on securing the required funding to get the Zandfontein underground mining restarted in 2022.”
