Clogau-St David's Gold Mine Update

Pitting of Waste Rock Dump Commences

Alba Mineral Resources plc (AIM: ALBA) is pleased to announce that the evaluation pitting of the historic waste rock dump at the Clogau-St David's Gold Mine ("Clogau" or the "Mine") will commence shortly.

Key Points

· The waste rock dump contains material derived from the internal development of the Clogau-St David's Gold Mine during past periods of production.

· The dump is estimated to cover about 30,000 square feet and to contain 20,000 tonnes of rock.

· Nine pits are to be dug, with around 15 tonnes of material to be extracted per pit. The material will be screened and a sample of the finer material from each pit will then be sent for gold assaying offsite.

George Frangeskides, Executive Chairman, commented:

"We are constantly looking for ways to unlock early revenue streams at Clogau-St David's while we continue with our work to prove up, through drilling, the new gold-bearing zones within the mine complex which will ultimately justify a decision to reopen the mine for long-term commercial production."

"One such potential source of early revenue is in the waste rock dump at Clogau. We estimate that this dump contains around 20,000 tonnes of rock extracted from the mine during previous periods of production, and we believe there are good prospects for finding significant quantities of gold in the finer grain-size fractions within the dump."

"Although we will be initially shifting a lot of rock in this exercise - around 135 tonnes of it - the samples that we will be screening, collecting and sending for assay will only weigh around 50-100kg per pit. Assuming normal processing times at our preferred external assay laboratory, we expect, therefore, to have a definitive answer on the gold-bearing potential of the waste rock dump by the middle of next month."

Detail

Within the Clogau mine site there is a waste rock dump which covers an estimated surface area of 2,833m² (approximately 30,000 square feet or 7/10ths of an acre), being up to 10m thick and containing an estimated 20,000 tonnes of waste rock originating from previous periods of mining at Clogau.

As most of the underground development was developed on the vein, Alba considers that it is likely that there are remnants of the quartz vein contained in the dump. The Company has designed a scheme for the sampling of the waste dump for gold content, which involves the digging and sampling of selective pits across the dump.

The waste rock dump comprises material which was derived from the internal development of the Clogau-St David's Gold Mine. The majority of the underground development comprised on-vein reef drives, from which stopes were developed. It is reported that six-foot blasting rounds were blasted in the development face and the large pieces of vein quartz were hand-sorted and sent to the Mine's processing plant. The finer material was cleaned out of the development end and sent to the adjacent waste rock dump.

It is Alba's opinion that there could be significant quantities of gold still left in the finer grain size fractions within the waste rock dump.

Accordingly, at this first stage the Company will be sampling the waste rock dump to test for its gold content. If the gold content is found to be sufficiently high-grade, the Company will then move to the next stage (subject to all regulatory approvals), being to extract large tonnages of the waste rock dump material and to then process the material in the Company's pilot processing plant. Most likely the pilot plant will first be modified and extended to enable it to handle the large tonnages which would be extracted from the waste rock dump.

As part of the current sampling phase, nine pits will be excavated, with each pit being up to 5 metres deep and up to 1.5 metres in diameter. This will result in around 15 tonnes of material being extracted per pit. That material will then be passed over a rock screen to screen out the oversize material. The undersized material will be thoroughly mixed on site and a 50-100 kg sample taken from it, with the remainder (~99.5%) of the excavated material being returned to the pit immediately following the sampling. Each pit has been sited so as to give a representative sample of the waste rock dump as a whole.

The composite samples will be transported to an assay laboratory where they will be screened into specified size fractions and each fraction assayed for its gold content.

The pitting exercise is expected to take up to two weeks, with the assaying of the composite samples then being subject to normal turn-around times at the off-site laboratory used by Alba.
