Pricing of the Private Placement was consistent with the equity consideration paid by the Company to purchase and cancel its outstanding $19.99 million 6 7/8% Convertible Senior Subordinated Notes ("Convertible Notes") as described below. The Private Placement allowed HCI to return to a near 26% interest in the Company, as it held prior to the purchase and cancellation of the Convertible Notes.

On February 11, 2022, the Company reported the privately negotiated purchase and cancellation of the Company's Convertible Notes maturing on July 1, 2022. The Company issued to the holders, on a private placement basis, an aggregate of 11,793,509 Common Shares of the Company at a price of $1.695 per share in consideration for the $19.99 million principal outstanding balance of the Convertible Notes. The Company paid accrued and unpaid interest on the Convertible Notes in cash.

On October 14, 2021, the Company reported completion of a geotechnical drilling campaign at the Waterberg Project. The campaign consisted of 46 boreholes drilled along the planned centerline of two sets of twin declines and box-cut positions. A total of 5,966 metres of drill core were recovered and a total of 2,696 metres of core were geotechnically logged from within the zone of interest. Downhole geophysical surveys were conducted. Core samples of all the major geotechnical units encountered were collected and subjected to laboratory testing. Geotechnical qualified persons monitoring the drill program have stated that in general, the rock mass encountered along both decline routes is competent and can support the planned excavations with no major problem areas expected.

Results For The Year Ended August 31, 2022

During fiscal 2022, the Company continued its efforts to lower costs. During the year ended August 31, 2022, the Company incurred a net loss of $8.24 million (August 31, 2021 - net loss of $13.1 million). The current year loss was lower primarily due to reduced interest expense of $1.7 million versus $5.1 million in fiscal 2021. All of the Company's $27.8 million in debt at August 31, 2021 was paid off during fiscal 2022. General and administrative expenses during the year were lower at $4.3 million (August 31, 2021 - $5.1 million).

Outlook

The Company's key business objective is to advance the Waterberg Project to a development and construction decision. PTM is the operator of the Waterberg Project as directed by a technical committee comprised of representatives from joint venture partners Impala Platinum Holdings Ltd. ("Implats"), Mnombo Wethu Consultants (Pty) Ltd. ("Mnombo"), Japan Organization for Metals and Energy Security (formerly Japan Oil, Gas and Metals National Corporation) ("JOGMEC") and Hanwa Co., Ltd. ("Hanwa"). Before project financing and a construction decision can be undertaken, arrangements will be required for project concentrate offtake or processing.

On October 18, 2022, Waterberg JV Co. approved in principle the pre-construction Work Program of approximately $21.0 million over a 23-month period ending August 31, 2024. The Work Program will focus on project infrastructure including initial road access, water supply, essential site facilities, a first phase accommodation lodge, a site construction power supply from state utility Eskom and advancement of the Waterberg Social & Labour Plan. An update to the 2019 Waterberg Definitive Feasibility Study ("DFS Update") is also planned, including a review of cut-off grades, mining methods, infrastructure plans, scheduling, concentrate offtake, dry stack tailings, costing and other potential revisions to the project's financial model.

From the Work Program the Initial Budget of approximately $2.5 million was approved for expenditure by March 31, 2023, and this work has now commenced. The Initial Budget includes an infill drilling program targeting near surface, modelled Inferred Mineral Resource blocks that have good potential for conversion to higher confidence levels, thereby allowing them to be added to early mine plans, potentially reducing early capital expenditure and the period to first mining. The infill drill program has commenced and is planned to consist of 16 T Zone NQ boreholes and 16 F Zone NQ boreholes. Mineralized material recovered from the drill program will be assayed and the remaining material will be processed to determine dry-stack tailings characteristics and provide additional concentrate metallurgical data. If dry stack tailings methods are implemented in the DFS Update, it is expected that mine water consumption will be reduced by 40% to 50%.

The Initial Budget for the Work Program is to be funded pro rata by the joint venture partners and was coordinated to match fiscal year and budgetary periods for JOGMEC and Hanwa. Subsequent expenditures in accordance with the Work Program are subject to expected approvals for sequential time periods ending on August 31, 2024.

The Company continues to work closely with regional and local communities and their leadership on mine development plans to achieve optimal outcomes and best value to all stakeholders.

The Company is considering commercial alternatives for mine development, financing and concentrate offtake. Obtaining reasonable terms for Waterberg concentrate offtake from an existing smelter/refiner in South Africa is considered the preferred option and discussions with such parties are ongoing. As an alternative to a traditional concentrate offtake arrangement, studies are also underway to assess the economic feasibility of constructing a matte furnace and base metal refinery to process Waterberg concentrate. The NI 43-101 definitive feasibility study technical report for the Waterberg Project entitled "Independent Technical Report, Waterberg Project Definitive Feasibility Study and Mineral Resource Update, Bushveld Complex, South Africa" dated October 4, 2019, stated that "Additional smelting capacity may need to be constructed in the industry to be able to treat the flotation concentrate from Waterberg and the other potential Platreef miners." A matte furnace and base metal refinery as described above is envisioned as a separate business from Waterberg JV Co. that could provide concentrate offtake terms to Waterberg JV Co. and possibly to other PGM miners. Discussions with potential participating partners and investors have occurred and are planned for the future.

As the world seeks to decarbonize and look for solutions to climate change, the unique properties of PGMs as powerful catalysts are being applied to various technologies as possible solutions for more efficient energy generation and storage. The Company's battery technology initiative through Lion with partner Anglo represents a new opportunity in the high-profile lithium battery research and innovation field. The investment in Lion creates a potential vertical integration with a broader industrial market development strategy to bring new technologies to market which use palladium and platinum. Research and development efforts by FIU on behalf of Lion continue. Technical results from Lion's research may have application to most lithium-ion battery chemistries and the scope of Lion's research work is being expanded.
