POSITIVE TECHNICAL STUDY COMPLETED – COPPER-GOLD-MOLY PORPHYRY PROSPECTS, DIVIDE BLOCK, 64NORTH PROJECT ALASKA
-
Resolution has undertaken a technical study of the Cu-Au-Mo porphyry 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

Figure 2 Looking south-west towards the Elaine Prospect, Divide Block, 64North Project.
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-class Pogo 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 CuAu-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.
While 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).
The 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 ).
The 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-V Tectonic Metals] and 190g/t rock chip at Western Trench prospect [ 10th November 2021 TSX-V Tectonic Metals ] and east of the Brink Project (diamond core intersections including 514.4m @ 0.427g/t Au [ 15th September 2020 TSX-V Tectonic Metals] ) ( Figure 1 ).

Historical work includes detailed soil sampling and rock chip sampling focussed on outcrop and subcropping areas with maximum rock chip values of 3.96g/t Au. The most elevated historical porphyry rock chip samples contain up to 0.76% Cu, 0.22g/t Au and 34ppm Mo ( RML ASX Announcement 26/11/2019 ). Resolution has extended the known extent of the mineralised porphyry system >1km to the south with an occurrence of 0.75g/t Au ( Figure 6 ) (new result - see JORC table and appendix).

ASX RELEASE
Propylitic alteration and disseminated sulphide mineralisation was observed within the quartz-felspar porphyry body mapped along the western margin of the Divide Block. This observation in conjunction with the presence of low-grade copper and molybdenite mineralisation could indicate proximity to a high-grade porphyry ore zone.
Surprisingly, there are multiple ridge lines, which remain unsampled including an area following a subtle magnetic trend to the north and another ridge line associated with discrete magnetic highs, with elevated soils at either end referred to as the George Prospect ( Figure 6 ). Magnetic highs are commonly associated with the core of porphyry deposits, associated with magnetite forming within the potassic alteration zone. The highest copper and gold grades are associated with the potassic alteration zone, so vectoring towards this is important.
Detailed mapping and surface geochemistry was completed in September 2021 to further assess the areas potential for both RIRGS and Porphyry mineralisation beyond the known prospects with assays expected in Q1 2022 ( Figure 6 ).
During January 2022, Resolution completed a fertility analysis, comparing whole rock analysis of intrusions from Divide, with the Pebble Deposit and other porphyry deposits worldwide. The analysis highlights a clear overlap in Sr/MnO vs Sr/Y and Sr/Y vs SiO2 fertility ratios between the Pebble Deposit and the Elaine Prospect. Pebble Sr/Y ratios range from 5-60 and SiO2 range from 60-75 wt%, according to whole-rock data presented by Olson, 2015, which overlap the bulk of the intrusions analysed from Divide ( Figure 7 ).
U-Pb zircon geochronology was completed on a porphyry sample from Elaine and returned an age of 94.96 ±0.84 Ma (GeoSep Services), similar to other mid-Cretaceous porphyries in Alaska, including the giant Pebble Cu-Au-Mo Deposit (~90Ma).
The combined results of the geochronology and the fertility analysis are extremely positive, given results are akin to the giant Pebble Deposit. Furthermore, the north-east trending district scale Serpentine Fault ( Figure 6 ), which forms part of the Black Mountain Tectonic Zone coincides with the Divide Block, which RML believes could have given rise to a potential major porphyry copper deposit. Intersections between continent-scale transverse fault zones and arc parallel structures have the potential to localise porphyry Cu generation through facilitating magma ascent in a porphyry system (Sillitoe, 2010).

Historical Drilling
Resolution Minerals has a historical exploration database covering a significant amount of the exploration work, which occurred across the 64North Project between 1998 and 2016. The dataset relating to the Divide Block covers 1999 to 2001, but upon field investigation has been found to be incomplete. Diamond drill core was located within tenure, which is not recorded in the database ( Figure 8 - 12 ). Resolution has been undertaking research and talking to local geologists to ascertain the full exploration history of the Divide Block. [ Explorers are not required to report exploration results to the geological surveys in the USA – hence previous exploration data is often lost ].
Core from two diamond drill holes were staged close to two metal casings sticking out of the ground, one dipping -40º, the other -50º and both directed due south (180º) ( Figure 9a ). Labels on the core boxes indicate the holes were drilled in the year 2000 with hole IDs (00ED-01 & 00ED-02).
The core was recovered via helicopter in September 2021. Logging and sampling has now been completed with assays expected in late Q1, 2022. Much of the core is intact as half core, with several sections of core missing, so presumably these sections visually had the highest potential for gold mineralisation. Despite some sections of missing core, re-analysis is considered extremely worthwhile, given explorers were focussed on gold exploration at the time and may have overlooked the significance of visible copper minerals and molybdenite in the core. Other drill platforms/staging areas were noted to the west of these collars (down slope). Enquiries are ongoing to ascertain the history of these platforms ( Figure 8 ).

Appendix 1. Why isn’t Pebble in Production?
Pebble was discovered in the late 1980s and is the largest undeveloped copper ore body in the world (Olson et al, 2020), however it has never gone into production. This doesn’t relate to the mineral economics of the deposit, but instead to complexities surrounding the location of the deposit and permitting, primarily relating to the potential impact on fish habitat. Pebble is positioned within a watershed, which drains into Bristol Bay, providing spawning habitat (freshwater tributaries) for 5 species of salmon. Bristol Bay itself supports salmon, herring, and other fisheries, which contributes 31% of Alaska’s annual seafood export, which in turn contributes $5.6B annually to the state’s economy. The Elaine Prospect is located much further inland and extremely unlikely to have significant impact on anadromous fish species.
