During the nine-month period ended May 31, 2022, the Company repaid both the Sprott Facility (as defined below) and Convertible Notes (as defined below). The Company believes that it will be able to settle its liabilities in the normal course as they come due for at least twelve months from the date of filing of these interim consolidated financial statements.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

The COVID-19 pandemic has had a material impact on the global economy, the scale and duration of which remain uncertain. Since March 2020, the pandemic has continued in waves and the emergence of the Omicron variant in late November 2021 caused a resurgence in new infections during the period. Related negative public health developments have again adversely affected workforces, economies and financial markets globally, resulting in continued economic uncertainty. Although to date the Company has not experienced a direct material adverse effect due to the pandemic, it is not possible for the Company to predict the duration or magnitude of the possible adverse results of the pandemic and its effects on the Company's business or ability to raise funds.&#160;On June 22, 2022, the Government of South Africa announced that the remaining COVID-19 regulations have been repealed.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Of the total project area, 20,532 hectares are covered by the Waterberg Mining Right. A further 40,983 hectares are covered by active prospecting rights and 4,488 hectares of rights under application. &lt;i&gt;&#160;&lt;/i&gt;On March 9, 2022, Waterberg JV Co. passed a resolution to apply for closure on 50,985 gross hectares of prospecting rights, of which 14,209 hectares are held within the granted mining right, leaving a net 36,776 hectares of uneconomic prospecting rights to be closed. After the prospecting right closures described above are filed and effective, the project area will cover 29,227 hectares, comprising&#160;of a granted mining right for 20,532 hectares, 4,207 hectares in active prospecting rights and 4,488 hectares of rights under application. Capitalized costs of $223 associated with the prospecting right closures were written off in the previous quarter ending February 28, 2022.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

One group filed an application for an order in the High Court of South Africa to review and set aside the decision by the Minister of the Department of Forestry, Fisheries, and the Environment to refuse condonation for the late filing of an appeal against the grant of an environmental authorization for the mine in November 2020. On July 30, 2021, Waterberg JV Co. received a restraint application filed in the High Court of South Africa by a group claiming to represent individuals located near planned surface infrastructure. On November 30, 2021, the actual host community where the planned infrastructure is to be located filed an application to join as a respondent to the restraint application. In their affidavit, the host community documented their support for the Waterberg Project. Waterberg JV Co. has filed answering affidavits and is opposing all court applications and all appeals received with respect to the Waterberg Mining Right. A time frame for the hearing of court applications or the settlement of appeals is uncertain or may never occur. The required court submissions in response to Waterberg JV Co.'s affidavits have not been filed by the various applicants. The Waterberg Mining Right currently remains active, was notarially executed by the DMR on April 13, 2021 and was registered at the Mineral and Petroleum Titles Registration Office on July 6, 2021.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Later, in March 2020 and after the Implats Transaction (defined below), in accordance with its mandate established by the government of Japan, JOGMEC completed the sale of a 9.755% interest in the Waterberg JV Co. to Hanwa Co., Ltd ("&lt;b&gt;Hanwa&lt;/b&gt;"). &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

("&lt;b&gt;Implats&lt;/b&gt;") purchased an aggregate 15% equity interest in Waterberg JV Co for $30 million. The Company sold an 8.6% interest for $17.2 million and JOGMEC sold a 6.4% interest for $12.8 million. As part of the transaction, Implats also acquired an option to increase its holdings in Waterberg JV Co. to 50.01% (the "&lt;b&gt;Purchase and Development Option&lt;/b&gt;") in exchange for certain payments and project funding, and a right of first refusal to enter into an offtake agreement, on commercial arm's-length terms, for the smelting and refining of mineral products from the Waterberg Project ("&lt;b&gt;Offtake ROFR&lt;/b&gt;") if Waterberg JV Co. proposes an offtake agreement with a third party. JOGMEC or its nominee retains a right to direct the marketing of Waterberg concentrate and to receive, at market prices, platinum, palladium, rhodium, gold, ruthenium, iridium, copper and nickel in refined mineral products at the volumes produced from the Waterberg Project. &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

                                                    &lt;p style="text-align: justify; margin-left: 36pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span&gt;&lt;span&gt;&lt;span&gt;&lt;span&gt;In October 2009, PTM RSA, JOGMEC and Mnombo entered into a joint venture agreement regarding the Waterberg Project (the "&lt;b&gt;JOGMEC Agreement&lt;/b&gt;"). Under the terms of the JOGMEC Agreement JOGMEC completed a $3.2 million work requirement to earn a 37% interest in the Waterberg JV property, leaving the Company with a 37% interest and Mnombo with a 26% interest. Following JOGMEC's earn-in, the Company funded Mnombo's 26% share of costs, totalling $1.12 million, until the earn-in phase of the joint venture ended in May 2012.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
                                                    &lt;p style="text-align: justify; margin-left: 36pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span&gt;&lt;span&gt;&lt;span&gt;&lt;span&gt;On November 7, 2011, the Company entered an agreement with Mnombo to acquire 49.9% of the issued and outstanding shares of Mnombo in exchange for a cash payment of R1.2 million and the Company's agreement to pay for Mnombo's 26% share of costs on the Waterberg JV property until the completion of a feasibility study. Mnombo's share of expenditures prior to this agreement, and Mnombo's share of expenditures post DFS, are still owed to the Company ($7.1 million at May 31, 2022). The portion of Mnombo not owned by the Company is accounted for as a non-controlling interest, calculated at $7.7 million at May 31, 2022 ($7.4 million - August 31, 2021).&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
                                                    &lt;p style="text-align: justify; margin-left: 36pt; margin-bottom: 0px;"&gt;&lt;span&gt;&lt;span style="text-align: justify;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;&lt;span style="font-size: 10pt;"&gt;To May 31, 2022, an aggregate total of $80.8 million has been funded by all parties for exploration and engineering on the Waterberg Project. Until the Waterberg prospecting rights were transferred to Waterberg JV Co., all costs incurred by other parties were treated as cost recoveries by the Company.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
                                                &lt;/div&gt;
                                            &lt;/div&gt;
                                        &lt;/div&gt;
                                    &lt;/div&gt;
                                &lt;/div&gt;
                            &lt;/div&gt;
                        &lt;/div&gt;

The Company received 400,000 common shares of Lion, valued at a price of $0.01 per share, as the original founder of Lion. On July 12, 2019, the Company and Anglo American Platinum Limited ("&lt;b&gt;Amplats&lt;/b&gt;") entered investment, shareholder and research agreements to facilitate Lion's objectives. Initially the Company and Amplats agreed to equally invest up to an aggregate of $4.0 million into Lion and on July 6, 2021 the Company and Amplats agreed to increase the planned funding to Lion by a further $2.73 million, to a total of up to $6.73 million, in order to allow the acceleration of certain research and commercialization activities (see below). All agreed funding into Lion by the Company and Amplats is to be exchanged for preferred shares of Lion at a price of $0.50 per share over an approximate three to five year period. Lion has been funded equally by both Anglo and the Company as follows:&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

On July 6, 2021 Lion agreed to increase the planned amount of research funding to FIU by a further amount of $1.0 million, for a total of up to $4.0 million. The first tranche to FIU under the SRA, totaling $1.0 million plus a one-time fee of $50, was funded by Lion in mid July 2019. Research work commenced at FIU during September 2019. During calendar 2020 FIU completed the first research milestone pursuant to the SRA, which triggered a second tranche of funding to FIU in the amount of $667. Based on research advancement, a third tranche in the amount of $667 was paid by Lion to FIU in February 2021. In February 2022 a fourth tranche of $500 was paid by Lion to FIU. Lion has provided aggregate research funding in the amount of $2.9 million to FIU as of May 31, 2022.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

The loan was immediately drawn and was originally scheduled to mature on August 14, 2021. Principal amounts of the Sprott Facility outstanding were charged interest at a rate of 11% per annum, compounded monthly. In August 2021 the Company elected to exercise an option to extend the maturity date of $10.0 million in principal by one year. At August 31, 2021, the nominal principal balance outstanding was $9.4 million which was fully repaid during the current period, bringing the nominal principal balance due as of May 31, 2022 to $Nil. Scheduled interest payments were made monthly with interest of $293 paid to Sprott during the nine-month period ended May 31, 2022 (May 31, 2021 - $1,282).&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

The Company's pledge of its South African assets as security against the Sprott Facility has been fully released. &lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

                                        &lt;p style="text-align: justify; margin-left: 36pt;"&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;&lt;span&gt;&lt;span&gt;The Convertible Notes contained multiple embedded derivatives (the "&lt;b&gt;Convertible Note Derivatives&lt;/b&gt;") relating to the conversion and redemption options. The Convertible Note Derivatives were valued upon initial recognition at fair value using partial differential equation methods at $5.38 million (see below). At inception, the debt portion of the Convertible Notes were reduced by the estimated fair value of the Convertible Note Derivatives of $5.38 million and transaction costs relating to the Convertible Notes of $1.05 million resulting in an opening balance of $13.57 million. The Convertible Notes were measured at amortized cost and were to be accreted to maturity over the term using the effective interest method. As the Convertible Notes were repaid before maturity a gain on the repayment of $144 was recognized in the current six-month period.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

During the period, 257,856 RSUs were settled. At May 31, 2022, 383,912 RSUs were issued and outstanding, with 3,334 of these RSUs being vested.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Through the terms of the May 2018 private placement, HCI acquired a right to nominate one person to the board of directors of the Company and a right to participate in future equity financings of the Company to maintain its pro-rata interest. HCI has exercised its right to nominate one person to the board of directors. During the period the Company closed a non-brokered private placement of 3,539,823 common shares at a price of US$1.695 per share for gross proceeds of $6 million maintaining HCI's ownership in the Company at approximately 26% at the time of the financing. At May 31, 2022, HCI's ownership of the Company was reported at 24,837,349 common shares, representing a 25.14% interest in the Company.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

                                            &lt;p style="text-align: justify; margin-left: 36pt;"&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;On November 23, 2017, definitive agreements were concluded to dispose of the share interests in Maseve Investments 11 (Pty) Ltd. ("&lt;b&gt;Maseve&lt;/b&gt;") to Royal Bafokeng Platinum Limited ("&lt;b&gt;RBPlat&lt;/b&gt;") in a transaction valued at approximately US $74.0 million (the "&lt;b&gt;Maseve Sale Transaction&lt;/b&gt;"). Maseve owned and operated the Maseve Mine. The Maseve Sale Transaction occurred as a scheme of arrangement (the "&lt;b&gt;Scheme&lt;/b&gt;") by way of two interdependent stages in accordance with section 115 of the South Africa Companies Act (the "&lt;b&gt;Companies Act&lt;/b&gt;"). Under the Scheme, Africa Wide was required to simultaneously dispose of its 17.1% interest together with the Company's 82.9% interest in Maseve. Stage one, being the sale of certain of Maseve's assets for approximately US $58 million in cash, was completed on April 5, 2018. Stage two, being the sale of 100% of Maseve's issued shares to RBPlat in exchange for RBPlat common shares, was completed on April 26, 2018.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
                                            &lt;p style="text-align: justify; margin-left: 36pt;"&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;In September 2018, the Company received a summons whereby by Africa Wide Mineral Prospecting and Exploration Proprietary Limited ("&lt;b&gt;Africa Wide&lt;/b&gt;") instituted legal proceedings in South Africa against PTM RSA, RBPlats and Maseve seeking to set aside the Maseve Sale Transaction. Various statements and discovery documents were filed during calendar 2021 and a trial to hear evidence occurred in the High Court of South Africa October 4 to October 8, 2021. Final legal arguments were heard by the High Court on March 1 and 2, 2022.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
                                            &lt;p style="text-align: justify; margin-left: 36pt;"&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;On June 14, 2022, the High Court of South Africa delivered judgement dismissing the challenge brought by Africa Wide and ordered Africa Wide to make payment of the defendants' &lt;/span&gt;&lt;/span&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;&lt;span style="font-size: 10pt;"&gt;costs, (this amount has not been accrued due to uncertainty of amount). I&lt;/span&gt;&lt;/span&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;n its ruling, the High Court found that Africa Wide had firstly failed to make its case on the evidence and secondly that, having failed to challenge the Scheme under the Companies Act, Africa Wide's case was statutorily barred. &lt;/span&gt;&lt;/span&gt;&lt;span style="font-size: 10pt;"&gt;&lt;span style="font-family: Times New Roman,Times,serif;"&gt;&lt;span style="color: black;"&gt;Africa Wide has filed an application for leave to appeal the judgment of the High Court and the Company intends to oppose the application.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
                                        &lt;/div&gt;
                                    &lt;/div&gt;
