The Company is deeply saddened to report a non-operational fatality during Q2 as a result of an off-site road accident that occurred during low visibility weather conditions. TSG remains wholly committed to achieving a zero-harm rate, and a thorough investigation has been undertaken following the incident. Additional safety training and education has been provided to employees and assistance given to the employee's family.

Alexander Dorogov, Chief Executive Officer of TSG, commented:

"We made solid operational progress in the first half of 2020. In spite of lockdown measures being implemented around the world due to the COVID-19 pandemic, we have managed to maintain our operations without interruption.

In addition, the second quarter of 2020 saw a return to substantially higher average gold grades as we began to process high-grade ore extracted from Vein 25 in the East Zone. We have made considerable progress in our mine development works at Vein 25 during the period, and these remain ahead of schedule. There is significant potential to explore additional areas around the East Zone and within close proximity to the Asacha Gold Mine.

We deeply regret the fatal accident which occurred in Q2 2020. The health and wellbeing of our people remains our absolute priority, and we remain committed to ensuring a safe working environment for all of our employees."

Commentary

TSG is pleased to report another busy and productive quarter, in which the Group has recorded significant production and exploration successes.

The Group achieved significant improvements in production performance from Q1 2020 despite gold mineralisation in the Main Zone becoming lower-grade and more erratic at depth. The average grade of the mill feed increased to 7.6 g/t which was in part supported by high-grade test ore extracted from Vein 25. Since April 2020, approximately 9,488 tonnes of ore with an average gold grade of 19.8 g/t has been extracted from Vein 25 and processed to produce approximately 6,028 oz of gold.

As announced on 10 July 2020, significant mine development work was completed at Vein 25 during the Quarter. The Group remains on track to commence commercial mining in the East Zone of the Asacha Gold Mine, which contains significantly higher grade ore, next year. Bulk sampling will continue for the remainder of 2020.

The planned 25,000 metres of exploration drilling over the Asacha licence area was completed during the Period. This has been a very successful campaign delineating additional mineral resources (see RNS announcement dated 16 June 2020) and identifying new exploration targets around the East Zone and within close proximity to the Asacha Gold Mine. Building on the successful drilling to date, a further 11,600 metres is planned to be drilled at Vein 25 North during the remainder of 2020.

In addition, the Group continues to progress with the evaluation of, and scoping study for, the development of the Rodnikova deposit, and expects to provide an update in the second half of this year.

As previously announced, the ongoing COVID-19 pandemic continues to have a limited impact on the Group's operations. Managing the health of the Group's staff is increasingly challenging as lock-down measures are eased. The Group remains vigilant, and strict protective and sanitary measures remain in place at our operations.

Existing guidance for 2020 production estimates remains unchanged.

TSG expects to publish unaudited interim financial results for H1 2020 in September 2020.
