"We are pleased to report on the progress made over a hugely productive and busy quarter. The team have made substantial advancements across all areas of the Vares Silver Project, from mine development to the processing plant, and we are gearing up for the initiation of all operations in the first quarter of 2024. Concurrently all infrastructure projects are now completed, and we are very proud that the first train has travelled down the newly refurbished railway line from Podlugovi to Vares.

Additionally, we have been very successful in our exploration efforts, and the updated Ore Reserves at Rupice and Rupice Northwest have increased the life of mine from 10 to 18 years. We are aiming to increase this further with a continuation of our successful exploration programmes to date. We have also announced our production guidance for the coming years, and we remain firmly committed to increasing future production."
