Key Points · · · · · · Drilling operations at the Amitsoq Island deposit have been completed. Drilling has confirmed the existence of two significant and laterally continuous graphite horizons, confirming Alba's existing geological model. All completed drillholes intersected either the Upper Graphite Layer ("UGL") or Lower Graphite Layer ("LGL") or both. Several graphite intersections are considerably thicker than expected from the modelling, up to 8.19m in the UGL and up to 15.54m in the LGL. Ground geophysics and sampling of the Kalaaq mainland discovery and environmental baseline studies have also been completed. Trenching of target areas at Kalaaq have revealed graphite beds up to 10m thick. Mark Austin, Alba's Chief Operating Officer, commented: "We are delighted to have encountered such thick graphite intersections at Amitsoq, well in excess of what we had projected from our structural modelling. We were also pleasantly surprised by the condition of the old mine workings and this will be an important factor as we move towards the long-term development of this very high-grade graphite project." "We will be sending the drill core to an accredited laboratory for assaying as soon as possible. The assay results will then be handed over to the independent competent person to assist in his resource estimation work." Details Alba subsidiary Obsidian Mining Limited ("Obsidian") has completed its planned diamonddrilling programme at the Amitsoq Island deposit, part of the Amitsoq Graphite Project, with the aim of establishing a maiden Mineral Resource there. A follow-up mapping and ground geophysical survey of the Kalaaq graphite deposit has also been completed on the mainland section of the Amitsoq licence area. Obsidian's field exploration team of geologists and assistants, drill crew and environmental contractors were accommodated on a chartered vessel anchored close to the drill site for the duration of the programme. Helicopter support was provided in order to transport equipment to site and to move the drill rig between pad locations. Of the five drill pads that had been prepared, only Pads A, B, C, and E were utilised. The most northerly location, Pad D, was not reached due to technical issues. All eight completed holes intersected graphite mineralisation, two from Pad A, three from Pad B and three from Pad E. A total of 935m were drilled. This was down on the planned 15 holes for up to 1,700 metres, principally due to ground conditions at Pads C and D. Although drilling was commenced from Pad C, it did not manage to attain the required depths to intersect the expected graphite horizons due to ground conditions. This will be revisited in the next drilling programme, using different techniques to counteract the ground conditions. The core was drilled initially using an HQ3 drill string but switched to NQ for the last two holes. Figure 3 (in the PDF version of this RNS) shows a photograph of the southern part of Amitsoq Island facing north-west and showing the position of the drillholes on the topography. Table 1 summarises the results of the drilling programme to date. Table 1: Summary of graphite intersections [NB: UTM 23N.

Five intersections of the Upper Graphite Layer have been recorded, measuring 8.19m, 7.09m, 3.65m, 2.96, and 3.81m (true widths), as well as five intersections of the Lower Graphite Layer, measuring 15.54m, 14.25m, 3.38, 0.45m and 7.23m (true widths). Figure 4 (in the PDF version of this RNS) shows the details of the holes drilled from Pad B. It is noteworthy that the intersections are generally greater in width than predicted by the geological model. In addition to the drilling, Obsidian's geological team have chip sampled the graphite outcrops in line with the drill fences in order to supplement the graphite mineralisation information to be used in the forthcoming resource estimation work. The graphite mine, which was abandoned in the 1930s, has been accessed and mapped by the geological team. Figure 7 (in the PDF version of this RNS) shows the condition of the workings and the scale of the graphite (the Lower Graphite Layer is shown in this photo) which is in agreement with some of the borehole intersection widths. The workings will be channel sampled in the next exploration campaign and will, undoubtably, contribute important information for the resource and future mining layouts. Other Field Work Kalaaq Exploration Programme A follow-up mapping and ground geophysical survey of the Kalaaq graphite deposit has been completed on the mainland section of the Amitsoq licence area. The programme was led by senior Greenlandic geologist Ole Christiansen, and involved extensive mapping and sampling, as well as a "beep mat" survey to record electromagnetic (EM) conductivity and magnetic susceptibility down to 3 metres below surface, through the overburden. This technique was used to great effect in 2017 to identify and map the graphite occurrences at Kalaaq. During the programme, the team excavated two trenches, revealing graphite zones. The Kalaaq area contains multiple horizons of graphite mineralisation that are interpreted to have been subject to complex folding. Average grades from sampling conducted at Kalaaq are 25.6% TGC, also among the highest of any project in the world. The results of this exploration programme will be used to refine drill targets at Kalaaq. Environmental Baseline Studies Experienced environmental consultants BioApp Greenland have completed the first-year environmental baseline screening programme at Amitsoq during this summer's field programme. The results of this work will form part of a future environmental impact assessment for the project, which will be a requirement for a future mining licence application.
