Amaroq expands Valley Block and records highest ever drill grade of 116g/t Au over 0.6m during the 2022 exploration programme
TORONTO, ON / ACCESSWIRE / December 7, 2022 / Amaroq Minerals Ltd. (AIM:AMRQ)(TSXV:AMRQ)(NASDAQ:AMRQ) an independent mine development corporation with a substantial land package of gold and strategic mineral assets covering an area of 7,866.85 km2 in Southern Greenland, provides the results of its 2022 exploration programme at Nalunaq.
Completion of 46 diamond core drillholes, on time and on budget, at Nalunaq. The holes infilled and extended the Valley Block, hitting the Main Vein in 42 holes, a success rate of 92% confirming the targeting ability of the Corporation's geological model
Main Vein intersections grading up to 116 g/t Au over 0.62m, the highest grade intersection drilled by the Corporation
Surface channel samples taken near existing underground infrastructure in the Mountain Block confirm thick, high-grade intersections of up to 98.6 g/t Au
Results indicate Valley Block has the potential to be as large as the Target Block which produced ~250 koz gold historically
Results illustrate that the Mountain Block may provide the lowest cost access to mineralisation through subsequent mine development
Significant progress made in defining and sampling a series of hanging wall veins both in the Valley and Mountain Blocks with grades received of up to 10.8 g/t Au in these newly identified veins
The main component of the 2023 exploration programme will be a large bulk sample, as a key step towards a maiden Mineral Reserve estimate. This programme has the potential to clearly demonstrate the revenue potential of the resource and be the first step toward full production
Eldur Olafsson, CEO of Amaroq, commented:
"Expanding the footprint of the Valley Block up to twice the size, with even higher grades sampled (116g/t Au) makes for exciting times at Amaroq Minerals. The 2022 Nalunaq exploration results, the most successful drilling campaign to date, build further on our understanding of the Valley Block. The results also provide additional evidence for the mining potential in Mountain Block. Significantly, the Corporation has two potential near term production areas ahead of commencing the 2023 Bulk Sample."

2022 Drilling Results
The 2022 programme consisted of 9,119 m of diamond core drilling across 46 drillholes. The objectives of the drill programme were to infill the existing resource and test an up-dip extension of the Valley Block ore-shoot. Of these drillholes, 42 or 92% intersected the Main Vein, a testament to the improved exploration efficiency from the Corporation's robust geological modelling of the last 24 months. Three of the remaining five drillholes, did not reach the depth of the Main Vein due to poor ground conditions and Amaroq will review if these will be redrilled during the 2023 exploration programme.

The drill programme was designed using the Corporation's new structural model, the ‘Dolerite Dyke Model' which was validated through the 2021 exploration results. Highlights of this programme include:
The intersection of 9 visible gold intervals confirming the existence of extensive free gold
Hole AEX2237 intersected 0.62 m @ 116 g/t Au, the highest grade drill intersect by Amaroq at Nalunaq, located on the extension to the Valley Block
Hole AEX2209 which intersected 0.56 m at 26.2 g/t Au
Figure 2. AEX2237 Main Vein intersection, 203.43 to 204.05 m grading 116 g/t AU
These results further confirm the existence of this high-grade zone and provided further data on the geometry of the Valley Block. Importantly the drill results extend the high-grade core of Valley Block ore-shoot up-dip around 300 m, making this recently discovered and previously unrecognised, high grade plunge a similar scale to the Target Block, the most productive part of the mine having produced around 250 koz historically.

In addition to the Main Vein intersections at the Valley Block, an additional mineralised vein structure was encountered in the hanging wall. This hanging wall vein, termed the JLP Vein, is more consistent than previously identified veins stratigraphically above the Main Vein and graded up to 50 cm at 3.85 g/t Au. The extent and potential of this vein series will be assessed further during 2023.
Further development during the 2022 season saw Amaroq invested in an optical televiewer, essentially a drill hole camera and survey device that allows the catchment of significantly more structural data.

2022 Surface Channel Sampling
In 1999 an extensive channel sampling campaign was undertaken on the outcropping Main Vein to improve confidence in grade continuity ahead of underground development. This sampling programme expanded on those undertaken in previous years by significantly increasing the sampling density. Samples were taken at 1 m intervals along the vein, beginning at an elevation of 470 m and continuing to 775 m, beyond which the vein became buried in scree and only sporadic sampling was possible.
In 2022, following the results of the Mineral Resource Estimate, which highlighted the significant potential for resource expansion in the Mountain Block area, Amaroq recognised the potential to increase the sampling density above 775 m elevation by exposing a new section of Main Vein between 820 and 830 m elevation. Ten metres of Main Vein was exposed and sampled using a diamond-blade rock saw. Channels were cut to represent the true thickness of mineralisation.
These channel samples returned very high-grade gold, up to 1.05 m @ 98.6 g/t Au, confirming grade continuity in this part of Mountain Block. Grades are similar to those of samples collected in 1992 from 830-840 m elevation, which range from 44.8 to 235.3 g/t Au over true vein thicknesses of approximately 1 m.
The opportunity remains to expose and sample the Main Vein between 775 and 820 m elevation.
The highest level developed underground in Mountain Block was the 720 m level, with a single exploration raise extended to 760 m level. These results therefore provide confidence that the mineralisation mined at the top of the Mountain Block extends at similar grades with thick intersections at least 100m vertically, providing yet further evidence of the near-term potential of this area of Nalunaq.

2022 Surface Channel Sample Locations
A new 3D model has been generated from drone images taken of the north face of Nalunaq mountain. The model is up to centimetre level resolution and was used to improve the accuracy of the Main Vein wireframe where it crops out on the north face (the Mountain Block area).
As with the drill results from the Valley Block, surface exploration at the Mountain Block identified at least two additional quartz veins in the hanging wall on the north face at approximately 35 and 75 metres above the Main Vein. A grab sample of the lower of these two hanging wall veins returned a grade of 10.8 g/t Au.
Amaroq intend to test the continuity and grade of these veins during the 2023 drilling programme, along with additional sampling of historic drill cores.

The Main Vein at Nalunaq is a laterally extensive shallowly dipping gold-bearing quartz vein with an average thickness of 70 cm in thickness. The vein hosts variable high gold grades of up to 5,240 g/t, with the mineralisation separated into high grade zones of up to 5,240 g/t and low-grade zones, both of which are controlled by the intersection of structures which Amaroq has defined in its Dolerite Dyke geological model.
This vein was mined between 2004 and 2013 and produced c.360,000 ounces of gold1. Amaroq is exploring for an Exploration Target of up to 2.0 Moz gold across the Main Vein and veins in the footwall and hanging wall as announced on September 16, 2020. Following a Mineral Resource Estimate update announced September 6th, 2022, the project hosts a CIM compliant Inferred Mineral Resource of 355.0 kt @ 28.0 g/t Au, with 320 koz gold.
The mine area is separated into five coherent zones termed the Mountain, Target, South, Valley and Welcome Blocks that constitute the highest grade areas of the Main Vein. Three of these blocks have experienced some historical mining with the Corporation concentrating its efforts in expanding resources up and down dip of these areas as well as developing previously unrecognised Blocks.
The 2022 exploration programme involved further core drilling, underground assessments, surface channel sampling and drone photogrammetry concentrated on the Valley and Mountain Blocks.

2023 Exploration Programme Objectives
Following a successful 2022 field season, Amaroq is planning the next development phase at Nalunaq. The Corporation intends to proceed with the extraction of a large bulk sample within one of the resource areas with the aim to upgrade the Mineral Resource, a further step towards a maiden Mineral Reserve estimate. The bulk sample will demonstrate the revenue generation potential of the resource and be the first step toward full production. Ahead of the bulk sample, Amaroq will conduct trade off studies to decide whether to source the material from the Valley or Mountain Blocks. The Corporation is in negotiation with various mining and construction contractors for this work.
Amaroq will also conduct a programme of surface drilling into the Mountain Block to further extend the Inferred Resources in this extremely high-grade zone of the project. Drilling may also be used to target generate in the newly defined Welcome Block area.

Containerised Preparation Laboratory
All 3,166 samples generated from Nalunaq, and the other Amaroq prospects, were submitted to ALS Geochemistry via the newly installed Containerised Preparation Laboratory (CPL). This facility was successfully commissioned in Q3 2022 and has allowed for a more robust sample preparation, transport and assay solution with more timely provision of assay results.
Sampling and QAQC Disclosure
Drill core was cut in half using a diamond blade core saw. Cut lines were consistently drawn along the core foliation axis and the right-hand side of the core was sampled. All drill core samples were placed into thick polymer bags with a sample ticket. All samples were prepared at ALS Geochemistry's containerised preparation laboratory on-site at Nalunaq, before being packaged and sent to an accredited laboratory, ALS Geochemistry, Loughrea, Ireland, for analysis.
Sample preparation scheme PREP-31BY was used on all samples. This involves crushing to 70% under 2 mm, rotary split off 1 kg, and pulverizing the split to better than 85% passing 75 microns. Samples were then analysed by 50 g fire assay with method Au-AA26 which has a detection limit of 0.01 ppm Au. Samples containing visible gold and samples considered to be the Main Vein were assayed with screen-metallics fire assay technique Au-SCR24 which has a detection limit of 0.05 ppm Au. This involves screening 1 kg of pulverised sample to 106 microns followed by a gravimetric assay of the entire plus fraction and a duplicate 50 g AAS assay of the minus fraction.
Amaroq's QA/QC program consists of the systematic insertion of certified reference materials of known gold content, blanks, and quarter core field duplicates at a rate of 1 in 20 or 5% per QA/QC type. In addition, ALS insert blanks and standards into the analytical process. The average sample mass was 2.08 kg.
