("Alba" or the "Company")
Alba completes gravity and soil sampling programme on its 100%
owned licence in Co. Limerick in Ireland
Alba Mineral Resources plc (AIM: ALBA) is pleased to announce
that it has completed a detailed gravity survey and soil sampling
programme on its 100% owned prospecting licence (PL3824) in County
Limerick in the Republic of Ireland (the "Survey").
The objective of the Survey is to identify possible structural
targets with associated gravity variations and soil geochemistry
anomalies that may be associated with the concentration of base
metal mineralisation, notably zinc and lead.
Alba's contractor has now demobilised from site and the detailed
results of the Survey are being processed and analysed prior to
expected release within the next few weeks.
Highlights
-- Survey completed over a total area of 400 ha.
-- 240 gravity stations measured and the results from each
station have now been sent to Alba's consulting geophysicist for
detailed analysis.
-- 277 soil samples taken. Following initial analysis by
portable XRF, anomalous samples to be dispatched to laboratory for
detailed multi-element analysis.
-- Survey objective is to identify new structural targets for drilling.
Survey details
The soil sample and gravity survey were completed over the same
area with sample/station spacing of 100 m and a line spacing of 150
m. Gravity data was recorded using a Scintrex CG-5 gravity meter,
with topographical data collected using a VRS (Virtual Reference
Station) GPS system. Soil samples were collected from a depth of
30-40 cm within the B soil horizon. Field work was carried out by
experienced staff from Aurum Exploration Services.
Photographs and maps from the Survey will shortly be available
on the Company's website.
Previous work undertaken to date at Limerick
Alba's work to date on prospecting licence PL3824 has consisted
of geological mapping, shallow soil geochemistry,
lithogeochemistry, VLF geophysics and drilling. Alba's joint
venture partner from 2010 to 2014, Teck Ireland, undertook a
microgravity study on the central part of the licence, and
completed four diamond drillholes.
The four diamond drill holes (totalling 956.7 m) were drilled in
2012. The holes were drilled to test the stratigraphy of the
licence and the mineral potential within Lower Carboniferous
limestone close to younger mafic lavas and intrusions (as present
at the Stonepark project 9 kilometres to the north). Drillhole
TC-3841-3 intercepted 6 metres of semi-massive and disseminated
pyrite between 508 and 514 metres within the target limestone. A 2
metre mineralised interval within the aforementioned interval
contained 0.58% Zn, and trace amounts of lead (208 ppm). The
presence of pyrite is encouraging since it often indicates the
presence of base metal sulphides at other properties in the
Limerick basin.
As announced on 26 July 2016, Alba's 100% owned prospecting
licence (PL3824) was renewed to 26 May 2018 and covers Base Metals,
Barytes, Gold and Silver.
Mike Nott, Alba's CEO, commented:
"We are pleased to report the completion of the current work
programme on our Limerick project, and eagerly await the processing
and interpretation of the data collected."
"The geology of the Pallas syncline in Co. Limerick is highly
prospective for zinc and lead mineralisation as exemplified by the
discovery of Glencore's Pallas Green project and Teck Ireland's
Stonepark project. We hope the results of our current exploration
programme will identify additional mineralisation and lead to
additional drilling on PL3824."
Glossary
Gravity surveys: a process that measures minute variations in
gravity. Gravity at every point on the surface of the earth varies
slightly depending on distance from the equator and density of the
underlying rock. A gravity survey is designed to pick up density
variations below the surface. The ability for rock density to be
detected using gravity variations is the basis for the use of
gravity surveys in mineral exploration. Gravity variations provide
an insight into different rock types and geological structures that
are otherwise hidden.
Soil sampling: a process of defining the location and shape of
an obscured mineralised structure and to identify any higher grade
sections within the structure. Once collected, samples are
submitted to a laboratory for analysis along with instructions as
to the suite of elements to be analysed and what the detection
limit should be.
XRF: X-ray fluorescence. The use of hand-held spectrometers
allows the user to make on-site geochemical analysis of mine face,
drill core or prepared samples, in order to identify quickly
whether or not a geochemical anomaly is being detected during the
programme. XRF spectrometers are designed to give an immediate
on-screen read-out of the presence and grade of mineralisation
within a tested sample.

About Alba
Alba holds a 15 per cent interest in Horse Hill Developments
Limited, the company which has a 65 per cent participating interest
and operatorship of the Horse Hill oil and gas project (licences
PEDL 137 and PEDL 246) in the UK Weald Basin. Alba is also earning
a 5% interest in Production Licence 235, which comprises the
producing onshore Brockham Oil Field.
Alba has the right to earn up to 70 per cent of the Amitsoq
Graphite Project in Southern Greenland. In addition, the Company
has recently renewed its Limerick base metal licence in the
Republic of Ireland, and has applied for the reissue of a uranium
permit in northern Mauritania. The new Mauritanian permit will be
on a reduced area, and is centred on known uranium-bearing
showings.
Alba continues actively to review and discuss numerous other
project opportunities which have value-enhancing potential for the
Company whether by acquisition, farm in or joint venture in a range
of jurisdictions around the world.
