The Arseno Ridge area is underlain by Devonian basaltic rock of Stikine Assemblage. Triassic to Jurassic quartz monzonite and Late Devonian intrusive rock of the McLymont Intrusive Suite are in contact with the basalts a few kilometres to the southeast.

The ridge west of the Arseno prospect (104B 432) where the Arseno Ridge occurrence is located was investigated in 2014 due to the geophysical anomaly identified there from a 2013 airborne geophysical survey. The lithologies in the area are beds of siltstone, conglomerate, andesites, and basalts, with rare jasperoidal alteration/replacement. One sample of 12 taken (Sample H234774) of vein material containing chalcopyrite and malachite graded 5.64 per cent copper, with no precious metal values; samples ranged up to 0.7 gram per tonne gold and 18.7 grams per tonne silver (sample H234863) (Assessment Report 35016). Sample H234774 was a subcrop grab from a calcite-ankerite vein, with clots of pyrite, chalcopyrite and malachite (2-3 per cent total), cutting black siltstone with prominent bedding. Sample H234863 was from andesite or very fine-grained sedimentary rock with 5 to 7 per cent quartz-calcite veinlets containing 1 to 3 per cent tetrahedrite-pyrite-chalcopyrite blebs.

WORK HISTORY

In 2013 Geotech Ltd. carried out a helicopter-borne electromagnetic (ZTEM) and aeromagnetic geophysical survey for Romios Gold Resources Inc over the Newmont Lake Block, comprising parts of the Newmont Lake property (Geophysics Report, Assessment Report 35016, Appendix VI). The following 21 mineral occurrences were covered by the survey: Ken (104B 027), 72 (Dirk) (104B (114), McLymont (104B 126), Northwest (McLymont), (104B 281), Jazzman (104B 282), Ridge (104B 325), Gab Northwest (104B 333), GAB 12 (104B 335), GAB 11 (104B 336), NEW (104B 379), Telena (104B 428), Bren (104B 429), Arseno (104B 432), Mon 2 (104B 433), Glacier Zone (104B 438), Camp Ridge (104B 441), Kirby NE (104B 442), Black Bear (104B 459), 2Bad (104B 460), Bridget (104B 462), O'Neil (104B 463).

In 2014, Romios Gold Resources Inc. conducted a prospecting and sampling program that included the evaluation of various showings and mineralized occurrences on the Newmont Lake and Trek Properties. A total of 314 rock chip samples and reconnaissance rock samples and 26 stream silt samples were collected.

In 2015, Romios Gold reported that a program of additional prospecting and sampling was carried out on the Burgundy Ridge discovery (Exploration and Mining in British Columbia 2015, page 135)

No work is reported for 2016 or 2017.

In January and February 2018, Geotech Ltd. carried out a helicopter-borne Versatile Domain Electromagnetic (VTEM) and aeromagnetic geophysical survey on behalf of Romios Gold Resources Inc. The survey covered three claim blocks: DIRK, KEN and NORTHWEST comprising parts of the Newmont Lake property and covered a total of 714 line-kilometres (Assessment Report 37492, containing Geotech Ltd Geophysical Report (Appendix Two)). The Northwest Block covers the following mineral occurrences: Northwest (McLymont), (104B 281), Jazzman (104B 282), Gab Northwest (104B 333), Cuba South (334), GAB 12 (104B 335), GAB 11 (104B 336), Arseno (104B 432), Syenite (104B 439), Cuba North (104B 440), Camp Ridge (104B 441), Kirby NE (104B 442), Kirby SE (104B 443), Thumper (104B 445), Black Bear (104B 459), Ray (104B 696), Arseno Ridge (104B 709), Vera (104B 710), Gerry (104B 713). The aeromagnetic survey shows the Arseno Ridge to be located in a magnetic low adjacent to a magnetic high area to the south. The nearest VTEM/ZTEM geophysical anomaly is located about 2 kilometre to the west-northwest where the Bren occurrence (104B 429)is located (Figure 24, Assessment Report 37492).

In December 2018, Crystal Lake Mining announced that it had acquired a 100 per cent interest in the 436 square kilometre Newmont Lake Project from Romios Gold.

In 2019, Crystal Lake conducted a drill program, on the Burgundy Ridge prospect area (104B 325) and the Northwest deposit. They also conducted extensive grassroots exploration.

See Northwest (104B 281) for a general work history of the Newmont Lake project area of Romios Gold work. Romios amalgamated much of the holdings in the area in the 2000s and acquired more by staking.
