Paterson Central - Drilling of Nimitz Prospect Completed

17 December 2020

Highlights

  • First Artemis drilling campaign completed at Paterson Central Project located next to the Newcrest Mining / Greatland Gold Havieron gold deposit in the Paterson Province, WA.
  • Three deep diamond holes were drilled only 2.5km to the east of Havieron in the Nimitz Prospect area for a total of 3,012m, with 1,151m drilled into Proterozoic bedrock of the Lamil Group, which is the host rock to the Havieron and Telfer gold deposits.
  • Drilling has provided core samples which provide visual indications that rocks in the Nimitz prospect area have potential to host gold and copper mineralisation.
  • Two drillholes (GDRCD001 and GDRCD003) testing Lamil Group rocks in the west (Nimitz South) are considered the best because they returned multiple zones of particularly intense hydrothermal alteration, with breccias flooded by carbonate- sericite andquartz-carbonate-chlorite veining, all associated with hematite and trace to minor pyrite and chalcopyrite.
  • All three holes drilled encountered intervals of intense hydrothermal alteration of upper Lamil Group rocks in close proximity to Havieron. This suggests that causative effects of alteration surrounding such a large gold system as seen at Havieron extend into, and occur on, the adjacent Artemis lease directly to the east. This supports the Company's belief that the Paterson Central licence is very fertile and prospective for large intrusive related gold and copper deposits.
  • Selected intervals of core were recovered during drilling for immediate assaying and petrological analysis based on visual estimates of alteration and brecciation. Results are from initial field samples are expected to be available early in the New Year, with larger sections of core analysis to follow.
  • Given these highly encouraging preliminary drilling observations, the Company is now planning an expanded 2021multi-rig drill programme to cover the top priority Apollo and Atlas targets, follow-up drilling at the Nimitz group of targets, and to test the Enterprise targets to the South.

Artemis Resources Limited("Artemis" or "the Company") (ASX:ARV, Frankfurt: ATY,

US OTCQB: ARTTF) is pleased to provide an update on mineral exploration activities at its 100%-owned Paterson Central Project located in the East Pilbara region of Western Australia.

Alastair Clayton, Executive Director commented:"These three drill holes, our first at the Paterson Central Project, are a watershed in our understanding of the potential for significant mineralised systems across our 605 sq km tenement footprint. The Nimitz group of targets were selected to be drilled in 2020 given relatively easy access from an existing Havieron main track, however, in reality, our highest priority ranked targets, Apollo and Atlas, will be drilled as soon as possible in 2021.

It is exceptionally significant that drilling has intersected large intervals of intensely hydrothermally altered breccias that are in places hematite overprinted and with trace to minor pyrite and chalcopyrite enrichment from our very first holes, with those testing the Nimitz South area seen as having the most potential. These are precisely the geological textures and features we are targeting and we are looking forward to receiving the first sets of assay and petrography results early in the New Year.

We are confident that we are generating the correct targets using a combination of geophysics, geochemistry and structural models and the drill core to date clearly demonstrates the geology at Nimitz is indeed fertile for intrusive related gold-copper deposits. By retaining 100% ownership of our licence we provide our shareholders with uniquely unencumbered leverage to continued exploration success in the Havieron area of the Paterson Province. Industry leading consultants Resource Potentials, led by Dr Jayson Meyers, undertook all of the field work during the programme and DDH1 were the drilling contractor."

First Drilling of Phase 1 Holes Completed - Basement Lithologies

Photographs of selected bedrock core intervals from holes GDRCD001 and GDRCD003, showing clear signs of hydrothermal alteration and veining, are shown in Figure 1. These photographs show a range of rock types and hydrothermal alteration styles that have affected the Proterozoic basement rocks close to the western tenement boundary with the Havieron Project. The scout drilling of these deep holes has provided core samples which provide early visual indications that rocks in the Nimitz Prospect area have potential to host gold and copper mineralisation, and results of petrographic analysis and geotechnical assay results will provide more geological insight into the gold and copper potential of the Nimitz Prospect area.

First Drilling of Phase 1 Holes Completed in Havieron Dune Corridor

Figure 2is a drone photograph showing the location of the Nimitz North drill pad in the foreground and Havieron in the background to the west.

The Company has identified 7 initial targets/prospects for deep drill testing at Paterson Central, with 5 of them surrounding the Havieron gold-copper deposit to the north, east and south (Figure 3). Drilling commenced at the Company's Nimitz Prospect in early October and was completed by mid-December. Nimitz was chosen because of its easily accessible location along an existing track that passes though Havieron and continues east into Artemis' Exploration Licence in a swale formed between 2 E-W trending linear sand dunes (Figure 3).

Figure 2:Night time drone photograph looking west showing Nimitz North drill pad in the foreground and Havieron drill rigs and camp lights in the background.

Information on the 3 deep diamond holes is presented in Table 1, which shows that a total of 3,012m were drilled, of which 1,151m were drilled into Proterozoic bedrock of the Lamil Group, the host rock to the Havieron and Telfer gold deposits, and the remainder was drilled through overlying Permian glacial deposit cover having an average vertical thickness of 568m, in comparison to about 450m at Havieron.

Figure 4shows simplified lithology initially logged from the core in the field plotted down the drillhole traces. About 70 short intervals of core (10-20cm long) were sampled in the field crossing key rock types, different alteration zones and veins of interest. These samples are being analysed for petrology and are being assayed for an extensive geochemical element suite. The remaining core will be properly measured, marked up, logged, cut, sampled and stored at Artemis' Radio Hill Mine site.

An extensive array of linear sand dunes show up as E-W trending lines, with topographic elevation highlighted by hotter colour attributes. The linear sand dunes range in height from 5 to 15 metres above the relatively flat landscape. The Nimitz Prospect is located 3km to the east of the centre of the Havieron deposit (3.4Moz Au), in the same inter-dune swale which was chosen for initial drilling due to relatively easy access.

Figure 4:3D view looking to the NW at Artemis deep drillholes into the Nimitz Prospect in the foreground coloured by simplified lithology down the hole traces. In the background are drillhole traces at Havieron up until end of September 2020 (taken from Newcrest quarterly reports to the ASX prior to the discovery of the Northern Breccia Zone at Havieron), and Artemis targets/prospects Apollo and Atlas.

The Nimitz Prospect is located on the western side of a broad NW-SE trending gravity ridge that runs along the eastern side of the Havieron Thrust Fault, and extends through the Artemis lease and into the adjacent lease containing Havieron (Figure 5). This gravity ridge is cut across to the south by an interpreted meandering paleo-valley incised into the top of the Proterozoic bedrock, and it is also cut across to the north by an interpreted granite batholith. This NW-SE gravity high trend can now be explained as an anticlinal structural corridor containing mafic sills within the Lamil Group based on the results from Artemis deep drillhole GDRCD003.

The company will now focus its next efforts on obtaining access to other targets/prospects within the Paterson Central Project area, with the aim to resume deep drilling on targets around Havieron and targets located further to the north in the first quarter of 2021.

Background to the Paterson Central Project

The Paterson Central Project is located in the Yaneena Basin of the Paterson Province, which hosts large scale mineral deposits, such as the World class Telfer Gold-Copper Mine, recently discovered Winu copper-gold deposit, Nifty Copper Mine, and the rapidly growing Havieron gold and copper deposit. The Company's Paterson Central project forms a 100% owned exploration tenement E45/5276, which surrounds the Havieron gold deposit on three sides, and covers the same continuous geological domain (Figure 6).

The geology of the project area consists of Canning Basin sediments - primarily Permian siltstones in this part of the basin - which overlie Proterozoic meta-sedimentary basement rocks which form the main host rocks to large mineral deposits in the region. The sedimentary cover is 300m thick in the far western part of the project area and is interpreted to deepen to over 800m in the far east. The Havieron gold and copper deposit is associated with a strong magnetic anomaly and sits under about 450m of sedimentary cover. Mineralisation at Havieron extends over deep intervals to at least 600m below the base of sedimentary cover, where the mineralisation starts, and it continues to remain open at depth and laterally, with the recent discovery of the Northern Breccia Zone by Newcrest. The Company is exploring the Paterson Central Project for both Havieron and Telfer styles of gold and copper mineralisation.

bedrock were collected from plastic core trays and broken into 10-20cm intervals

using a hammer. The sample intervals were marked on remaining core, and core

sample intervals were geologically logged, measured for average length,

photographed, and placed into numbered calico bags.

Remaining core samples were stored in plastic core trays, stacked onto pallets and

lashed to pallets with metal strapping for transport to the Company's Radio Hill

Mine site in WA, where the core will be properly measured, marked up, logged in

greater detail, cut for assaying, and stored.

Logging

Initial logging has been carried out visually to produce simple lithological quick-logs,

and more detailed geological logging and core measurements will be carried out on

properly measured and marked up core in a core farm.

Sub-sampling

Spot samples of core collected in the field will be cut by rock saw to remove small

techniques and

blocks of rock to use for generating thin section slides for petrographic and

sample

microscopic analysis. Such petrological samples will also be photographed. This

split into 2 samples by using a rock saw to cut down the middle of the core, or

laboratory tests

disaggregated core samples will be broken and manually split, so that duplicate

samples can be analysed for repeatability

Certified standard sample packs of representative Au-Cu mineralized rock will be

submitted with every 20 core samples for additional QA/QC.

Verification of sampling and assaying

Location of data points

  • Laboratory standards and blank samples will be inserted at regular intervals and duplicate samples will be taken for QC checks at a ratio of 1 to 20 core samples.
  • Coordinate and height information were collected with a differential GPS (DGPS) using the GDA94 datum and MGA Zone 51 projection accurate to within 1m.
  • Where DGPS survey information was not available, locations were measured using a handheld GPS accurate to within 5m and the SRTM digital elevation model or Landgate 2010 digital elevation model was used as a height datum.
  • Downhole hole position surveys were collected at 30m intervals using a north seeking gyroscopic downhole survey tool operated by DDH1.

Data spacing

Core samples 10-20cm long were collected in the field were taken at random

and distribution

intervals based on visual changes in host geology, overprinting hydrothermal

alteration effects or veining for immediate analysis by the Company.

SECTION 2 REPORTING OF EXPLORATION RESULTS

(Criteria listed in the preceding section also apply to this section.)

Criteria

Commentary

Mineral tenement and

Drilling was entirely carried out within the Company's exploration licence E45/5276, which

land tenure status

is 100% owned by Artemis Resources Limited and forms the Central Paterson Project.

This tenement was granted on 14 February 2019 and remains in good standing.

Exploration done by

All previous exploration activity in area was for oil and gas in the sedimentary basin rocks

other parties

of the Canning Basin, which sit on top of the older Proterozoic basement rocks which is

the current target hist rock for the Company's Au-Cu exploration activities.

Geology

The project occurs in the Neoproterozoic Yaneena Basin of WA (852-820Ma), which is

comprised of sandstone, carbonate, marl, siltstone, shale and ironstone beds intruded by

mafic sills forming the Throssell and overlying Lamil groups, and which both overlie the

Rudall Metamorphic Complex basement (ca 1,800Ma). The Crofton Granite Suite was

intruded into the region during the Miles Orogeny (650-600Ma), when large gold-copper

deposits like Telfer were deposited. The Yaneena Basin underwent several phases of

deformation, with last major event being the Paterson Orogen at ca 550Ma. Much of the

host rocks to the gold and copper deposits are covered by Permian glacial deposits of the

Paterson Formation / Grant Group of the Canning Basin, and Cainozoic sediments, sand

dunes and regolith soil cover blanket much of the region. The style of mineralisation within

the Company's project area is currently unknown, but inferred to be related to intrusive

related gold, mesothermal-orogenic lode gold, or skarn styles of gold mineralisation, with

elevated copper.

Drill hole Information
