AIM - WINNERS

Alba Minerals Resources PLC, up 53% at 0.17 pence, 12-month range 0.090p- 0.23p. The northern Europe-focused mineral explorer wins ecological permits required for its planned dewatering and exploration of the primary target within the Clogau-St David's gold mine in north Wales. Says technical team and contractors are preparing the site to begin dewatering as soon as possible. "Detailed planning has been in train for some time so that we did not lose time once the permits were granted. Accordingly, we are well placed to complete our preparations on site and commence the dewatering exercise within a matter of days," says Executive Chair George Frangeskides.

The service is expected to launch in January 2024.

AIM - LOSERS

----------

Aptamer Group PLC, down 35% at 4.40p, 12-month range 3.01p-100.0p. The custom affinity binder developer warns it is running low on cash, with cash balance at the end of June standing at just GBP200,000. Consequently, requires short-term funding, and is reviewing "all possible financing options that are in the best interests of the company and its shareholder". Also reports decline in annual revenue, expecting around GBP1.8 million in the financial year ended June 30, which would be down 55% from GBP4.0 million the year before.

----------

Restore PLC, down 30% at 160.20p, 12-month range 160.0p-466.0p. The provider of digital and information management and lifecycle services says profit is likely to be below expectations, as its chief executive leaves with immediate effect. Says adjusted pretax profit in 2023 will be lower than the GBP31 million that is expected. Adjusted pretax profit in 2022 amounted to GBP41.0 million, so it expects a decline of roughly a quarter or more. Plans to cut permanent staff headcount by 230, in roles across senior managers, sales, support functions and operations. CEO Charles Bligh stands down by "mutual consent", with Senior Independent Director Jamie Hopkins taking the helm on an interim basis. Additionally, Chair Sharon Baylay-Bell becomes executive chair, also with immediate effect.
