Investee Company Update: GreenRoc Mining plc

Alba Mineral Resources plc (AIM: ALBA) i s pleased to note the announcement today by its portfolio company, GreenRoc Mining plc ("GreenRoc") (AIM: GROC), in which Alba holds a 54% majority interest. Following on from Alba's announcement on 11 August 2021 of the completion of the drilling programme at the Amitsoq Graphite Project in southern Greenland, GreenRoc's announcement today details the strong assay results which have now been received from that drilling programme, as well as from an associated channel sampling programme, and which has confirmed Amitsoq as one of the highest-grade graphite projects globally.

Alba's Executive Chairman, George Frangeskides, commented:

"These exciting results from GreenRoc's drilling and sampling programme at the Amitsoq Graphite Project further confirm the consistently high-grade nature of the deposit, the significant widths of the graphite layers and, therefore, the potential for a sizeable JORC Resource. Given graphite's expanding role in many green energy solutions, we look forward to the step-out drilling programme next year as GreenRoc progresses along the path to becoming a supplier of this highly sought-after critical mineral."

The announcement by GreenRoc is set out below without material changes:

Amitsoq Graphite Project Update

Confirmation of High-Grade Graphite Drill Intercepts

GreenRoc Mining plc (AIM: GROC) is pleased to announce the full suite of assay results from its drilling and channel sampling programme undertaken at the Amitsoq Island deposit from June to August 2021. These results confirm the high-grade nature of the Amitsoq Island deposit as well as showing the graphite layers to be both thicker, and more consistent, than previously thought.

Key Points

-- High-grade graphite mineralisation confirmed and increasing true widths observed down dip on both the upper and lower graphite layers, supporting the potential for a sizeable JORC Resource

-- Lower Graphite Layer (LGL) returns drill intercepts grading up to 23.01% C(g) and channel samples grading up to 30.35% C(g)

-- Upper Graphite Layer (UGL) returns drill intercepts grading up to 19.83% C(g) and channel samples grading up to 27.40% C(g)

   --      Significant true width thickness of graphite layers confirmed by drilling, including: 

o LGL: 15.60 m @ 22.34% C(g) from 93.61 m

o LGL: 14.95 m @ 22.82% C(g) from 102.19 m

-- Deposit open along strike (predominantly to the north) and down dip, which will be tested in Phase 2 drilling programme

   --      Significant down-dip extensions and increase in thickness from surface outcrop 
   --      Strike length of LGL intersected from Pads B and E totals 154 m 

-- Low-grade uranium content poses no problems for future development under new Greenlandic legislation

-- Drilling campaign confirms Amitsoq to be one of the highest-grade graphite deposits globally

-- These results will be a key element in the mineral resource estimation assessment to be made by the Competent Person in due course.

GreenRoc's CEO, Kirk Adams, commented:

"These results from the 2021 drilling campaign confirm the Amitsoq Island deposit as one of the highest-grade graphite deposits in the world.

"In addition, the consistency of grades, combined with the increasing true widths observed down dip at both graphite layers, represents particularly encouraging news and bodes well for the resource potential at the Amitsoq Island deposit.

"In the lower graphite layer, the drill core assays are grading up to 23.01% contained graphite, with an average of 22.56%. Furthermore, the drilling has shown that the true width of this layer below the old open pit mine widens with depth, increasing from 13.2 m to 14.95 m at around 100 m down dip from surface.

"The upper graphite layer also shows similar consistency, with drill core assays of up to 19.83%, and an average of 18.91%, contained graphite. This upper mineralised zone also shows increasing true widths with depth.

"This update gives us confidence for the step-out drilling programme which we have planned for 2022 and we are positive about the prospects for the ultimate resumption of mining at the Amitsoq Island deposit."

Details

GreenRoc has received the drill core and channel sample assays from the phase 1 drilling programme on the Amitsoq Island graphite deposit that took place between June and August 2021. Drilling was conducted at four drill pads along the island's ridge to test the down-dip continuation of the Upper Graphite Layer (UGL) and the Lower Graphite Layer (LGL), which outcrop along the eastern face of the island. The assay results are set out in Tables 1 and 2.

Results

Pad A

Hole AM-DD-013A intersected the UGL from 20.94 m with a true thickness of 8.05 m, giving a down-dip continuation of 27 m from the surface outcrop. Additionally, the UGL swells from a max thickness of 2.66 m at the surface to 8.05 m (true thickness) in hole AM-DD-013A (Tables 1 & 2). A drill pad along the western face of the island has been planned for the Phase 2 programme which will further test the down-dip extension and swell of the UGL.

Four-channel sample transects were taken along the extent of the UGL outcrop below Pad A, with an average grade of 22.08% C(g) across the outcrop and individual samples grading up to 26.1% C(g).

Pad B

Both the UGL and LGL were intersected in holes drilled at Pad B. Hole AM-DD-006 intersected 16.49 m @ 22.82 C(g) from 102.19 m; this intercept gives the LGL a down-dip continuation of 91 m from the open-cut at the surface. More importantly, the LGL maintains a significant thickness down-dip from the surface, swelling from 13.20 m (true thickness) in the open-cut to 14.95 m (true thickness) in AM-DD-006 (Tables 1 & 2). Hole AM-DD-005 intersected 15.60 m @ 22.34% C(g) from 93.61 m, which includes a high-grade interval of 2.72 m @ 23.96% C(g) from 104.55 m.

The intersection of the UGL in hole AM-DD-004 gives a down-dip continuation of 54 m from the surface outcrop. Like the UGL intersections at Pad A, the UGL intersections at Pad B increase in thickness down-dip from 2.03 m at the surface to 3.97 m (true thickness) in hole AM-DD-006, almost doubling in thickness (Tables 1 & 2).

Additional drill holes on the western face of the island have been planned to test further the down-dip continuation of both the UGL and LGL.

Two channel sample transects of the UGL were taken below Pad B. The channel sample from B-UGL-2 returned 2.03 m @ 27.40% C(g) and the average grade across the two outcrops is 26.96% C(g).

PAD E

All three holes at Pad E intersected the LGL, which increases in thickness considerable down-dip, from 0.59 m (true thickness) in AM-DD-009 to 7.08 m (true thickness) in AM-DD-015 (Tables 1 & 2). As a result, the down-dip continuation from AM-DD-009 to AM-DD-015 is 75 m. As mentioned above, for Pads A and B, the planned phase 2 holes will test the down-dip continuation and the significant increasing thickness of the layer down-dip.

From the Phase 1 programme, hole AM-DD-015 returned the highest-grade drill core intercept of 8.18 m @ 23.01% C(g) from 113 m, including 3.06 m @ 25.17% C(g) from 114.38 m. Also, AM-DD-015 includes individual samples grading up to 27.60% C(g).

The strike length of the LGL between pad B and E is 154 m. The LGL is still open along strike to the north and will be targeted in the Phase 2 drilling by stepping back at pad C out of the fault zone and drilling from a pad further north.

LGL Channel Sampling

There is limited outcrop of the LGL (except the open cut) due to historic mine development, overburden and boulder cover. However, four channel sample transects were taken from around the mine site area, with individual samples grading up to 32.4% C(g). Most notable, the high-grade LGL-4 samples were taken from extruding outcrops within a historic trench from 1915; the historic trenching reported the LGL to be 13.20 m wide (true thickness).

The LGL was the main horizon worked underground. Therefore, Phase 2 drilling will be accompanied by underground channel sampling, contributing to important information for the resource and future mine layout.

Assays Within Legal Limits for Uranium

In total, 43 drill core samples were sent for multi-element analysis, of which 25 samples were from the graphite ore horizons, and the other 17 samples were either vein, hanging wall or footwall material. The average uranium concentration for all 43 samples and 25 ore samples is 42.71 ppm and 65.59 ppm, respectively. Thus, the uranium concentration in the graphite ore horizon is significantly below the maximum threshold recently set by new legislation passed by the Greenland parliament. This legislation prohibits the exploration and exploitation of uranium projects, save that the prohibition does not apply, where the exploration or exploitation is focused on a mineral other than uranium (e.g. graphite, ilmenite, iron ore, gold or base metals), if the average uranium content of the total resource is below 100 ppm.

As such, the new legislation does not pose any issues for the development and future exploitation of the Amitsoq Deposit.

Next Steps

The complete dataset from the Phase 1 drill core and channel sample assays will form a key component of the mineral resource estimation assessment to be made by the Competent Person.

In preparation for Phase 2 drilling, discussions have been held with key contractors including drilling companies. The Company has had wooden storm-proof stairways constructed at key points on Amitsoq Island, to facilitate future drilling.

GreenRoc have also received the results of the first-year baseline environmental studies carried out by the Company's environmental consultants, BioApp. The environmental and ecological data thereby obtained will inform the design of the second year of baseline studies which the Company intends to carry out next year, leading into the formal environmental and social impact studies required to apply for a mining licence for Amitsoq.
