POSITIVE TECHNICAL STUDY COMPLETED - COPPER-GOLD-MOLY PORPHYRY PROSPECTS, DIVIDE BLOCK, 64NORTH PROJECT ALASKA
Resolution has undertaken a technical study of the Cu-Au-Moporphyry and gold potential of the Divide Block, 64North Project, Alaska
The study concludes the Elaine Prospect has affinities with the giant Pebble Deposit in SE-Alaska(37Mt Cu, 39Moz Au) - equivalent age and whole rock fertility signature
The Elaine Prospect Porphyry is large scale and located within the same porphyritic belt, which hosts large scale Cu-Au-Mo porphyry deposits such as Casino in the Yukon, Canada Drill core from previous gold explorers was recovered from the Elaine Prospect containing chalcopyrite, Cu oxides, molybdenite, arsenopyrite within quartz veins and porphyry stock
Historical core has been logged and sampled with assay results expected late Q1, 2022 Geophysics surveys are planned during the 2022 summer field season to define drill targets

As we begin our third season in Alaska, and really start to get "under the hood" of the rocks in this region, the prospect pipeline continues to surprise on the upside with opportunities often overlooked or not followed up by previous explorers as focus was drawn elsewhere.
The Elaine Cu-Au-Mo Porphyry Prospect is a hidden gem of a prospect and a potential significant
opportunity overlooked by the rush and focus for gold surrounding the neighbouring world-classpersonalPogo Gold Mine.
Encouragingly the giant Pebble Cu-Au-Mo Porphyry Deposit and Resolution's Elaine Prospect are the same age and share the same whole rock fertility signature from studies undertaken by Resolution, leading us to re-rate the prospect to warrant working up drill targets.
Resolution's exploration team has diligently worked in the background on assessment of the Elaine Prospect amongst other prospects, over the last two and half years and identified the scale potential and prospectivity of the opportunity for the Company.
The heavily endowed Tintina Gold Province extends across central Alaska and the Yukon, Canada, and famously hosts >100m oz of gold deposits collectively. Often overlooked is the giant sized Cu- Au-Mo porphyry deposits and prospects, such as the nearby Casino deposit with 4.9Mt contained copper and 21Moz of gold over the border in the Yukon, Canada. The world's largest undeveloped copper deposit, aptly named "Pebble" sits at the SW of tip of Alaska and hosts a staggering 37Mt (Cu) of copper and 117Moz (Au) of gold.
ForWhile the focus for the summer 2022 field season will be to drill the Tourmaline Ridge prospect. Alongside that, our team will quantify the scale potential and prospectivity of the Elaine, George and Kramer Prospects, with the aim of defining drill targets using geophysics surveys and surface sampling during the summer of 2022.

Regional Cu-Au-Mo Porphyry potential
The Tintina Gold Province is a 2,000 km long, highly endowed belt, which extends across central Alaska (US), through the Yukon Territory and into northern British Columbia (Canada) (Figure 4). There are more than 100Moz of combined Au resources known to be hosted within the Tintina Gold Province, the majority of which are classified as Reduced Intrusion Related Gold Style (RIRGS). However, the Tintina is also prospective for Cu-Au-Mo porphyry mineralisation as demonstrated by the giant Casino porphyry deposit (Yukon, Canada), which contains Combined Resources (Inferred, Measured & Indicated) of 4.92Moz Au, 21.1Mt Cu, 0.51Mt Mo and 168.7Moz Ag (Figure 4 & 5, Table 1).
Major porphyry deposits commonly cluster along linear belts, which extend for up to hundreds of kilometres long such as the Tintina, but also occur less commonly in apparent isolation e.g., Pebble in Alaska, Butte in Montana, and Bingham in Utah (Sillitoe, 2010).
ForThe Pebble Cu-Au-Mo porphyry deposit located in south-west Alaska is an example of an apparent isolated deposit and contains Combined Resources (Measured & Indicated) of 117Moz Au, 37Mt Cu, 2.56Mt Mo and 574Moz Ag and is the largest undeveloped copper ore body in the world (Figure 4, Table 1, Appendix 1).
The Elaine Prospect porphyry is located within the same geological setting at Casino (continental arc), albeit related to older Pebble-aged intrusions, within a zone defined as being prospective for porphyry mineralisation by the United States Geological Survey (USGS) (Kreiner et al, 2020) (Figure 5). Previously unknown historical drill core was located on the ground at Divide and has been recovered, logged, and submitted for analysis. The core contains chalcopyrite, Cu oxides, molybdenite & arsenopyrite within quartz veins (Figure 3, Figure 8 - 12) and porphyry stock.

Divide Block Overview
The Divide Block is prospective for two styles of mineralisation:
- Porphyry Cu-Au-Mo (Elaine & George Prospects); and
- Reduced Intrusion Related Au (Kramer Prospect) (Figure 6).
ForThe Divide Block is located south of the Tectonic Metal's Tibbs Project (RAB intersection of 9.14m @ 6.71g/t Au [5th September 2020 TSX-VTectonic Metals] and 190g/t rock chip at Western Trench prospect [10th November 2021 TSX-VTectonic Metals] and east of the Brink Project (diamond core intersections including 514.4m @ 0.427g/t Au [15th September 2020 TSX-VTectonic Metals]) (Figure 1).
