Latest Sampling Results Expand Areas of Gold Mineralisation

at Clogau Gold Project


Alba Mineral Resources plc (AIM: ALBA) Alba (AIM: ALBA), the diversified mineral exploration and development company, is pleased to report the second set of results from the 2019 soil sampling campaign being undertaken within the Company's 107 km2 licence area in North Wales.  Alba's Clogau Gold Project hosts the high-grade Clogau-St David's gold mine as well as the extensive regional target known as the Dolgellau Gold Belt.





·     Results have been obtained from a further 243 samples from the recently completed 1,200 sample programme. 


·     Gold-in-soil grades from two new anomalies away from the existing mine area and not associated with historic mine workings range in grade from 0.005 to 0.25 g/t Au (at a 0.005 g/t cut-off).


·    Previously reported anomalies have been extended in strike length based on the new results.


·    Average grades for the new anomalies are well above the average gold-in soil grades for Clogau-St David's and the other historic mine areas.


·    In total, results have now been received for 768 samples of the 1,200 sample programme, or 898 sampling results including the 2018 sampling programme.


·     Gold mineralisation has now been confirmed across ~6 miles along the strike extent of the Dolgellau Gold Belt and from within multiple geological units.


·   The 1,200 sample programme has been completed and the field team has commenced Phase 2 of the programme involving infill and extension sampling.


Alba's Executive Chairman, George Frangeskides, commented:

"Our regional exploration of the Dolgellau Gold Belt continues to bear fruit.  We have now confirmed mineralisation across around six miles of the Gold Belt, and in total have identified seven new mineralised zones which are not associated with historic mine workings.  The fact that the average grades for those zones exceeds the equivalent grades obtained over the Clogau-St David' s mine itself is genuinely exciting."

"Our exploration team is back in the field now, and conducting infill and extension sampling, as we seek to increase our knowledge and understanding of these new gold zones. We will report further developments as they arise."

Soil Sampling Programme

Ongoing soil sampling and geochemical analysis is being carried out within the Dolgellau Gold Belt with samples generally collected at ~20 m intervals on lines ~200 m apart.  This exploration programme is the first of its kind, utilising modern-day exploration techniques, that has been undertaken on the Dolgellau Gold Belt since the first discovery of gold and base metals there during the 18th century.

The current field programme complements and expands upon the orientation programme that was completed in the summer of 2018.  During that orientation programme, soil sampling was undertaken in the area above and immediately adjacent to the existing Clogau-St David's mine.  This confirmed the presence of an associated gold-in-soil anomaly and thereby confirmed the validity of the exploration technique which is now being rolled out across extensive regional targets within the wider licence area.

At each sample location, a sample is being taken from the B soil horizon (subsoil) by hand auger. The results from the current programme have been taken from a total of 768 soil samples and were submitted for assay at the accredited ALS laboratory in Ireland. To date, including the 130 samples collected in the summer of 2018, results have been received from a total of 898 submitted samples.  The team has now completed the initial 1,200 samples and has commenced infill and extension sampling based on the new results obtained.

For further details on the sampling results, see the pdf version of this RNS where Figure 1 highlights the targets identified to date from the sampling programme, being new targets based on the most recent batch of samples results and previously reported anomalies, both believed to occur where limited or no mining activities have taken place. The new anomalies require detailed ground-truthing although it is understood that no significant mining activities have occurred in these areas.

Figure 2 in the pdf version of this RNS shows the locations of all 898 samples collected and assayed to date. Sampling to date, including those with assays still pending, covers a strike extent along the Dolgellau Gold Belt of approximately 7.5 miles.

Figure 3 in the pdf version of this RNS shows all the results obtained to date which have a laboratory gold detection limit of at least 0.001 ppm (equivalent to 0.001 g/t) Au. The assay results for the gold-in-soil show a restricted dispersion halo away from the predicted historic targets. Given the limited weathering and thin soil profile above bedrock, the anomalous values are considered likely to be close to source and the sampling highlights that low gold-in-soil levels can be significant anomaly indicators given the fact that we have previously confirmed the presence of a low-grade anomaly associated with the Clogau-St David's mine, which we know to have historically produced a significant amount of high-grade gold and which we consider to be prospective for additional gold mineralisation.   

The results show that gold-in-soil grades above the detection limit occur at multiple locations within the areas sampled to date. Elevated values correspond with the known mine areas as well as multiple locations that appear to be unaffected by mining activities, thus some appear to represent potential bedrock sources of gold rather than being due to contamination. This includes a sample returning an assay of 0.65 g/t Au that lies within the Gamlan Formation and is associated with an igneous intrusive body that may represent an ore-controlling feature at the Clogau Mine. This is an area which will undergo further investigation.

The results obtained to date highlight multiple anomalies across a range of geological features. This is not surprising given the historic mining in the region targeted gold and base metals from various lithological units. Traditionally, however, gold was mined from within the Clogau Shale (shown in blue in Figures 2 and 3 in the pdf version of this RNS) and it is clear from the results obtained that a continuous anomaly is present within this unit.  However, elevated gold values are also now observed at contacts between the Clogau Shale / Maentwrog boundary (shown in light grey in Figures 2 and 3 in the pdf version of this RNS) and within the Gamlan Formation (shown in dark grey in Figures 2 and 3 in the pdf version of this RNS) that do not appear to have been the focus for most of the historic mining activities. Results from the latest batch of samples are, however, located predominantly within the Clogau Shale unit.

If the samples collected within the preliminary target boundaries of a grade equal to or above 0.005 ppm are compared with those samples of that same grade which were taken within the "historic" anomaly boundaries, it is clear that the average grade of the samples across the new anomalies is very comparable to the average grade of the samples from the "historic" anomalies (see Table 1, below).  Indeed, at the current level of investigation, the average grades for new anomalies 1 and 2 are well above the averages for Clogau-St David's and the other historic mine areas.

B soil horizon: Commonly referred to as "subsoil" and typically consists of clay or minerals such as iron or aluminium oxides and minor organic material. Plant roots penetrate through this layer, but it has very little humus.


Clogau Shale: A dark-grey or black-banded carbonaceous mudstone and silty mudstone.


Geochemical: Relates to the chemical composition of the Earth and its rocks and minerals.


Geophysics: The application of the methods and techniques of physics to the study of the earth and the processes affecting it.


Hand Auger: A hand tool with a long blade that resembles a screw, which drills narrow diameter holes when turned.


Intrusives: An igneous rock formed from magma forced into older rocks at depth within the Earth's crust, which then typically slowly solidifies below the Earth's surface.


Lithological Units: The lithology of a rock unit is a description of its physical characteristics visible at outcrop, in hand or core samples or with low magnification microscopy, such as colour, texture, grain size, and mineral composition.


Lithological Contacts: The contact between two lithologies of differing characteristics.


Mineralisation: Economically important metals that can occur at a variety of scales from small disseminations through to large zones or ore bodies.


Pathfinder Elements: In geochemical exploration, an element that occurs in close association with an element or commodity being sought, but one can be more easily identified because it forms a broader halo or can be detected more readily by analytical methods.


Quartz Veins: A distinct sheet-like body dominantly composed of quartz hosted within a rock formation.


Strike Length: The direction and length of a geological feature (for example, a vein or rock formation) measured on a horizontal surface.


Structural Architecture: The three-dimensional distribution of bodies of rock, as controlled by geological structures.


Weathering Profile: A vertical assemblage of weathering zones (subsurface zones of alteration differing physically, chemically or mineralogically from adjacent zones) from the surface soil to the unaltered bedrock.
