Alba Mineral Resources plc
("Alba" or the "Company")
Structural Geology Field Work at Amitsoq
Extends Strike Length at Mainland Discovery
Alba Mineral Resources plc (AIM: ALBA) is pleased to announce that it has now completed a second phase of the summer 2017 field work programme at the high-grade Amitsoq Graphite Project in southern Greenland (the "Project"). The purpose of the field work was to carry out a detailed review of the structural geology and setting of the known graphite horizons both in and around the former graphite mine at Amitsoq, as well as at the new mainland graphite discovery reported in our announcement of 18 July 2017, now referred to as the Kalaaq Mainland Discovery. In addition a ground electromagnetic (EM) geophysical survey was carried out at the mainland discovery.
The initial results of the second phase of the Company's summer 2017 field work programme are summarised below.
Highlights
· The ground geophysical survey has identified additional graphite beds at the Kalaaq Mainland Discovery, in addition to those discovered in the field work earlier this year.
· Tracing the graphite beds southwards indicates that a zone consisting of multiple thick graphite layers is present for a distance of at least 460 m.
· The structural geology field work has also identified drilling targets in the vicinity of the historic mine. The two graphite beds in the area were traced over a distance of approximately 1000 m.
· Detailed satellite images are in the process of being acquired over both main graphite horizons, which will be used to construct accurate topographic maps that can then be used to refine proposed drilling locations.
· Channel samples taken at the Kalaaq Mainland Discovery are being dispatched to SGS in Canada for detailed metallurgical test work designed to confirm metallurgical characteristics of the Kalaaq discovery and in particular whether it displays the same metallurgical characteristics to the high-grade graphite found in the area of the former Amitsoq mine.
George Frangeskides, Alba's Executive Chairman, commented:
"I am excited by the exploration results for the Kalaaq Mainland Discovery. As we perform additional work in this new discovery zone, we continue to expand the area of graphite mineralization, and identify zones of structurally thickened mineralization. The present study indicates that the mineralization remains open to the south, and the down-dip extensions remain untested."
"We were already very encouraged by this year's work at Amitsoq, in and around the former mine site on Amitsoq Island. However, this discovery of a whole new graphite deposit on the mainland portion of our licence represents more than just a "bonus"; it could be a real game changer for the economic viability of the Project overall".
Second stage field work completed
As reported on 18 July 2017, in the first part of the field work programme at the Amitsoq graphite project (the "Project") undertaken during this past summer, the outcomes included the following:
· Several of the airborne EM anomalies identified in the EM Survey were confirmed as graphite horizons along strike and proximal to the Amitsoq graphite mine.
· Two new areas of thick graphite accumulation were identified:
o The first area is located 8.75 km to the north-east of the former Amitsoq mine, and corresponds to a strong EM anomaly, with a true thickness of at least 4.85 m.
o The second area is located on the mainland portion of Alba's licence, 11.5 km north-northeast from Nanortalik, and consists of at least three beds of apparently purer graphite than the Amitsoq mine area, with true thicknesses of 6.3, 4.9 and 3.6 m. These beds (the Kalaaq Mainland Discovery) represent a new graphite discovery.
These significant developments have now been further consolidated and advanced in a second phase of the summer 2017 field work programme, further described below.
Geological field mapping and a coincident ground electromagnetic (EM) survey, supervised by SRK Exploration Services led by Senior Exploration Geologist Dr Jeroen Van Gool, was undertaken at the Kalaaq Mainland Discovery in September 2017. The field work supports the earlier (July 2017) interpretation by Alba fieldwork that the area contains multiple beds of graphite orientated in a general north-south trend in the northern part of the zone, and a more south-westerly trend in the southern (upland) extension. Based on visual observations and ground geophysics, the graphite beds appear to connect and are locally repeated by folding. The true thickness of the graphite beds are generally 2 to 3 m over much of their length, but increase locally to 7 m in the south. Where the beds have been folded, the true thickness could be up to 15 m.
Due to the soil cover in some of the areas the beds do not always outcrop, and the thickness is based on the ground EM survey. However, to rule out the possibility of locally transported (scree) material causing the anomalies, several pits were dug over the EM anomalies. The pitting confirmed that the anomalies were due to bedrock graphite.
Tracing the graphite bed to the north, towards the coast, was hampered by several metres of glacial moraine overlying the bedrock in the area. The EM survey did, however, pick up some weak signal along the trace of the beds. Mapping in July 2017 identified a thin (0.8 m) graphite horizon on the coast. Tracing the upper bed southward indicated that this thick (more than 3 m) graphite horizon is present for a distance of at least 460 m, possibly more based on satellite image interpretation.
SRK Exploration Services also performed structural mapping in the vicinity of the former Amitsoq mine. The two graphite beds in the area were traced over a distance of approximately 1000 m and structural measurements recorded. These measurements were used to update the geology map of the island, determine controls on the variable thickness of the graphite beds, and help predict the distribution of graphite at depth. All of these interpretations were then used to refine the location of proposed drilling sites.
Final approval is being sought from the Greenland government to export channel samples from two of the graphite horizons at the Kalaaq Mainland Discovery collected in early August. These samples, along with a 5 m composite chip sample from the upper graphite horizon at the former Amitsoq mine, are being sent to SGS Canada Inc in Ontario for metallurgical testing.
Field Team
Structural mapping and technical supervision during this second stage field work programme was performed by Dr. Jeroen Van Gool, Senior Exploration Geologist, SRK Exploration Services Denmark, a branch of SRK Exploration Services Limited UK. Dr. Van Gool has previously worked with the Geological Survey of Denmark and Greenland (1999-2008) and has also performed exploration work in Greenland for several years as a consulting geologist on a variety of commodities.
Next Steps
The Company is awaiting completion of the acquisition of satellite images over the main targets areas at Amitsoq and at the Mainland Discovery. This will enable Alba to refine the drilling locations which have been selected for the maiden drilling campaign at the Project.
