SOUTHGOBI RESOURCES ANNOUNCES FOURTH QUARTER AND FULL YEAR 2020 FINANCIAL AND OPERATING RESULTS
HONG KONG – SouthGobi Resources Ltd. (Toronto Stock Exchange (“TSX”): SGQ, Hong Kong Stock Exchange (“HKEX”): 1878) (the “Company” or “SouthGobi”) today announces its financial and operating results for the quarter and the year ended December 31, 2020. All figures are in U.S. dollars (“USD”) unless otherwise stated.
The Board of Directors (the “Board”) wish to inform that the Company’s independent auditors, BDO Limited (“BDO”), have completed their audit of the consolidated financial statements of the Company for the year ended December 31, 2020 in accordance with Canadian generally accepted auditing standards and would like to announce the audited annual results of the Company for the year ended December 31, 2020 together with the comparative figures for the previous year and the respective notes in this announcement.
SIGNIFICANT EVENTS AND HIGHLIGHTS
The Company’s significant events and highlights for the year ended December 31, 2020 and the subsequent period to March 30, 2021 are as follows:
- Operating Results – The Company’s sales volume decreased from 3.7 million tonnes in 2019 to 2.6 million tonnes in 2020 due to the impact of the Coronavirus Disease 2019 (“COVID-19”) pandemic. The average selling price of coal decreased from $34.9 per tonne in 2019 to $33.0 per tonne in 2020. The decrease in the average selling price was principally attributable to a higher portion of sales made at the mine gate instead of transporting the coal to the Company’s Inner Mongolia subsidiary and selling to third party customers within China.
- Financial Results – The Company recorded a $15.3 million profit from operations in 2020 compared to a $29.8 million profit in 2019. The financial results were impacted by (i) the closure of the Mongolia-China border beginning as of February 11, 2020 which resulted in the Company being unable to export its coal products to China during the first quarter of 2020; (ii) the export volume limitation imposed following the reopening of the Mongolia-China border on a trial basis on March 28, 2020; and (iii) the provision for commercial arbitration of $4.6 million recorded in connection with the Company entering into a settlement agreement with First Concept Industrial Group Limited (“First Concept”) on June 7, 2020.

- Impact of the COVID-19 Pandemic – The Company was informed that effective as of February 11, 2020, the Mongolian State Emergency Commission closed Mongolia’s southern border with China in order to prevent the spread of COVID-19. Accordingly, the Company suspended coal exports to China beginning as of February 11, 2020 as a result of the border closure.
On March 28, 2020, the Mongolia-China border was re-opened for coal export on a trial basis, with a limit imposed on the total volume of coal that was permitted to be exported during this trial period. The Company has experienced a continuous improvement in the volume of coal exported to China since March 28, 2020.
The border closure had an adverse impact on the Company’s sales and cash flows in the first and second quarter of 2020. In order to mitigate the financial impact of the border closure and preserve its working capital, the Company temporarily ceased major mining operations (including coal mining), reduced production to only coal-blending activities and placed approximately half of its workforce on furlough in February 2020. On August 2, 2020, the Company resumed its mining operations. Although the export of coal from Mongolia to China continues as of the date hereof, there can be no guarantee that the Company will be able to continue exporting coal to China, or the border crossings would not be the subject of additional closure as a result of COVID-19 or any variants thereof in the future. The Company will continue to closely monitor the development of the COVID-19 pandemic and the impact it has on coal exports to China and will react promptly to preserve the working capital of the Company.
In the event that the Company’s ability to export coal into the Chinese market becomes restricted or limited again as a result of any future restrictions which may be implemented at the Mongolia-China border crossing, this is expected to have a material adverse effect on the business and operations of the Company and may negatively affect the price and volatility of the Common Shares and any investment in such shares could suffer a significant decline or total loss in value.
- China Investment Corporation (together with its wholly-owned subsidiaries and affiliates, “CIC”) convertible debenture (“CIC Convertible Debenture”) – On February 19, 2020, the Company and CIC entered into an agreement (the “2020 February Deferral Agreement”) pursuant to which CIC agreed to grant the Company a deferral of: (i) deferred cash interest and deferral fees of $1.3 million and $2.0 million (collectively, the “2020 February Deferral Amounts”) which were due and payable to CIC on January 19, 2020 and February 19, 2020, respectively, under the deferral agreement signed on April 23, 2019 (the “2019 Deferral Agreement”); and (ii) approximately $0.7 million of fees (the “Management Fee”) which was due and payable on February 14, 2020 to CIC under the amended and restated mutual cooperation agreement dated November 19, 2009 (the “Amended and Restated Cooperation Agreement”).

On October 29, 2020, the Company obtained an order from the British Columbia Securities Commission (the “BCSC”), the Company’s principal securities regulator in Canada, which partially revoked the CTO (as defined below) to, amongst other things, permit the Company to execute the 2020 November Deferral Agreement. The 2020 November Deferral Agreement became effective on January 21, 2021, being the date on which the 2020 November Deferral Agreement was approved by shareholders at the Company’s annual and special meeting of shareholders. As a consequence of the Company not entering into a deferral agreement with CIC as at December 31, 2020, International Accounting Standard (“IAS”) 1 requires the Company to classify the entire balance of the CIC Convertible Debenture as a current liability as at December 31, 2020.
The principal terms of the 2020 November Deferral Agreement are as follows:
- Payment of the 2020 November Deferral Amounts will be deferred until August 31, 2023.
- CIC agreed to waive its rights arising from any default or event default under the CIC Convertible Debenture as a result of trading in the Common Shares being halted on the TSX beginning as of June 19, 2020 and suspended on the HKEX beginning as of August 17, 2020, in each case for a period of more than five trading days.
- As consideration for the deferral of the 2020 November Deferral Amounts, the Company agreed to pay CIC: (i) a deferral fee equal to 6.4% per annum on the 2020 November Deferral Amounts payable under the CIC Convertible Debenture and the 2020 June Deferral Agreement, commencing on the date on which each such 2020 November Deferral Amounts would otherwise have been due and payable under the CIC Convertible Debenture or the June 2020 Deferral Agreement, as applicable; and (ii) a deferral fee equal to 2.5% per annum on the 2020 November Deferral Amounts payable under the Amended and Restated Cooperation Agreement, commencing on the date on which the Management Fee would otherwise have been due and payable under the Amended and Restated Cooperation Agreement.
- The 2020 November Deferral Agreement does not contemplate a fixed repayment schedule for the 2020 November Deferral Amounts and related deferral fees. Instead, the Company and CIC would agree to assess in good faith the Company’s financial condition and working capital position on a monthly basis and determine the amount, if any, of the 2020 November Deferral Amounts and related deferral fees that the Company is able to repay under the CIC Convertible Debenture, the June 2020 Deferral Agreement or the Amended and Restated Cooperation Agreement, having regard to the working capital requirements of the Company’s operations and business at such time and with the view of ensuring that the Company’s operations and business would not be materially prejudiced as a result of any repayment.
- 6 -
- Commencing as of November 19, 2020 and until such time as the November 2020 PIK Interest is fully repaid, CIC reserves the right to require the Company to pay and satisfy the amount of the November 2020 PIK Interest, either in full or in part, by way of issuing and delivering PIK interest shares in accordance with the CIC Convertible Debenture provided that, on the date of issuance of such shares, the Common Shares are listed and trading on at least one stock exchange.
- If at any time before the 2020 November Deferral Amounts and related deferral fees are fully repaid, the Company proposes to appoint, replace or terminate one or more of its Chief Executive Officer, its Chief Financial Officer or any other senior executive(s) in charge of its principal business function or its principal subsidiary, then the Company must first consult with, and obtain written consent from CIC prior to effecting such appointment, replacement or termination.

The Full Settlement Sum was fully satisfied by the Company in June 2020 and the outstanding payable to First Concept as of the date hereof is $nil.
- Cease Trade Order and Halt Trading on TSX – On June 19, 2020, the BCSC issued a general “failure to file” cease trade order (“CTO”), to prohibit the trading by any person of any securities of the Company in Canada. Trading in the Common Shares on the TSX was halted as a result of the CTO.

Overview of Annual Operational Data
As at December 31, 2020, the Company had a lost time injury frequency rate of 0.03 per 200,000 man hours based on a rolling 12-month average.
The Company experienced a decrease in the average selling price of coal from $34.9 per tonne in 2019 to $33.0 per tonne in 2020 as a result of a higher portion of sales made at the mine gate instead of transporting the coal to the Company’s Inner Mongolia subsidiary and selling to third party customers within China.
The product mix for 2020 consisted of approximately 39% of premium semi-soft coking coal, 54% of standard semi-soft coking coal/premium thermal coal and 7% of washed coal compared to approximately 18% of premium semi-soft coking coal, 63% of standard semi-soft coking coal/ premium thermal coal, 17% of washed coal and 2% of standard thermal coal in 2019.
Sales volume decreased from 3.7 million tonnes in 2019 to 2.6 million tonnes in 2020.
The Company’s production in 2020 was lower than 2019 as a result of the temporary cessation of the Company’s major mining operations (including coal mining) during February to August 2020 for the purpose of mitigating the financial impact of the border closure and preserving the Company’s working capital, yielding 1.5 million tonnes for 2020 as compared to 5.1 million tonnes for 2019.
The Company’s unit cost of sales of product sold for 2020 was $22.3 per tonne, which is similar to $22.6 per tonne for 2019.

Overview of Annual Financial Results
The Company recorded a $15.3 million profit from operations in 2020 compared to a $29.8 million profit in 2019. The financial results were impacted by (i) the closure of the Mongolia-China border beginning as of February 11, 2020 which resulted in the Company being unable to export its coal products to China during the first quarter of 2020; (ii) the export volume limitation imposed following the reopening of the Mongolia-China border on a trial basis on March 28, 2020; and (iii) the provision for commercial arbitration of $4.6 million recorded in connection with the Company entering into a settlement agreement with First Concept on June 7, 2020.
Revenue was $86.0 million in 2020 compared to $129.7 million in 2019. The Company’s effective royalty rate for 2020, based on the Company’s average realized selling price of $33.0 per tonne, was 12.2% or $4.0 per tonne, compared to 8.9% or $3.1 per tonne in 2019 (based on the average realized selling price of $34.9 per tonne). The increase in effective royalty rate was mainly due to the new royalty regime introduced by the Government of Mongolia in the third quarter of 2019.
- 12 -
Royalty regime in Mongolia
The royalty regime in Mongolia is evolving and has been subject to change since 2012.
On September 4, 2019, the Government of Mongolia issued a further resolution in connection with the royalty regime. From September 1, 2019 onwards, in the event that the contract sales price is less than the reference price as determined by the Government of Mongolia by more than 30%, then the royalty payable will be calculated based on the Mongolian government’s reference price instead of the contract sales price.
Cost of sales was $58.7 million in 2020 compared to $84.4 million in 2019. The decrease in cost of sales in 2020 was mainly due to the effect of decreased sales volume. Cost of sales consists of operating expenses, share-based compensation expense, equipment depreciation, depletion of mineral properties, royalties, coal stockpile inventory impairment/(reversal of impairment) and idled mine asset costs. Operating expenses in cost of sales reflect the total cash costs of product sold (a non-IFRS financial measure, refer to section “Non-IFRS Financial Measures” for further analysis) during the year.

| Cost of sales related to idled mine assets | 4,853 | 3,998 |
| Cost of sales | $ 58,657 $ | 84,400 |
Operating expenses in cost of sales were $37.0 million in 2020 compared to $59.5 million in 2019. The overall decrease in operating expenses was primarily due to the decreased sales volume from 3.7 million tonnes in 2019 to 2.6 million tonnes in 2020.
Cost of sales in 2019 included a reversal of impairment of coal stockpile inventories of $1.8 million, to increase the carrying value of the Company’s coal stockpiles to the lower of the cost and the net realizable value. The reversal of impairment of coal stockpile inventories recorded in 2019 reflected the enhancement in the wash plant capacity and its continuous operation at the expected level.
Cost of sales related to idled mine assets in 2020 included $4.9 million related to depreciation expenses for idled equipment (2019: $4.0 million).
