The Northwest Zone (McLymont Creek property, McLymont 3 claim) is underlain by Mississippian and Permian sediments and volcanics of the Stikine Assemblage. The Mississippian package structurally overlies Permian stratigraphy along a northeast trending, steeply dipping reverse or thrust fault. The Mississippian stratigraphy consists of a thin bedded clastic marine succession comprising coarse crinoidal limestone, siltstone, sandstone, turbidites, lesser chert and polymictic conglomerate. Permian(?) stratigraphy consists of hornblende-plagioclase porphyritic maroon andesite breccia flows, maroon lahar, lapilli tuff, and associated volcanic sediments. Quartz rich granite pluton intrudes the stratified rocks and occurs as dikes along pervasive northeast trending faults. This granite is thought to be Middle Jurassic in age.

The strata are intruded by a diverse suite of intrusive rocks ranging from the Late Devonian Mclymont Plutonic Suite to Eocene intrusions of the Coast Plutonic Suite.

Gold mineralization is associated with major steeply dipping north-easterly trending structures. Mineralization occurs as stratabound replacement type bodies and replacement mantos within and along contacts of gently dipping Mississippian marble and chert layers. Locally, the marble is replaced by extensive barite and barite/pyrite breccia. Gold is associated with silver and copper, zinc and lead are associated with pyrite, magnetite, chalcopyrite, specular hematite, calcite, quartz and minor barite.

In 1987, an 11.2 metre intersection from drill hole 87-29 assayed 55.02 grams per tonne gold, 1362.14 grams per tonne silver and 0.97 per cent copper. Another 9.1 metre intersection from drill hole 87-25 assayed 13.85 grams per tonne gold, 3.77 grams per tonne silver and 0.23 per cent copper (Gulf International Minerals Ltd., 1988 Information Circular). A rock chip sample, taken from the Northwest grid area, assayed 15.09 grams per tonne gold and 7.54 grams per tonne silver (Assessment Report 16932).

Diamond drilling in 1989, defined mineralization in the Northwest Zone along a strike length of 300 metres to a depth of 200 metres. Selected samples assayed 6.58 grams per tonne gold and 4.80 grams per tonne silver over a 7.2 metre intersection (drill hole 89-59), 10.59 grams per tonne gold, 3.43 grams per tonne silver, and 0.11 per cent copper over a 3.9 metre intersection (drill hole 89-64) (Gulf International Minerals Limited, Press Release, 1989).

The understanding of the mineralization is complicated by easterly trending left-lateral faults, which offset the mineralization. Mineralization is hosted by limestones and limy sediments and consists of pyrite, chalcopyrite and magnetite. Typical skarn assemblage mineralogy is common, leading previous workers to propose a retrograde skarn model for the Northwest zone. Extensive drilling has helped to delineate the mineralization, but the controls are still not well understood.

In 2005, consulting geologist Gerald Ray reported on the Northwest zone as follows (abridged) (Assessment Report 29085, pages 29 to 31): "The northeast trending McLymont structure marks the western boundary of the Newmont Lake Graben, and its true dip is unknown although it is probably steeply inclined to east. The rocks on both sides of the fault are cut by northerly striking structures that probably represent second-order splays from the main fault. These secondary structures commonly contain strong Fe-carbonate alteration and are often marked topographically by deep narrow gulleys. The Mississippian succession includes an upper part dominated by massive ash andesitic ash and lapilli tuffs with thin units of marble. Lower down, where the mineralization occurs, there is a sequence of bedded to massive tuffs, thin-bedded siltstones, and horizons of white to grey marble that carry crinoids. Excellent grading in the siltstones cut by drilling indicate the package is upright. Poorly defined bedding suggest that the main area of past drilling lies close to a north trending and north plunging fold. Jaramillo (personal communication, 1990) believed that the western limb of this fold dips 35 to 75 degrees northwest while the eastern limb dips steeply southeast. This poorly understood structure may have partly controlled some of the ore zones. The deposit plunges gently northwards and has been traced by drilling for greater than 300 metres. Orebodies occur both in steep, narrow, possibly fault-controlled zones, and in gently dipping and thicker units that have apparently replaced the marbles and calcareous siltstones. In one area, several steeply dipping mineralized shoots pass up into an extensive, sulfide-rich area known during the time of the Gulf International exploration as the “Mushroom Zone”. Mineralization is sporadically associated with enhanced values of Pb, Zn, As, Co, Sb, Bi and Te. It principally consists of pyrite and lesser magnetite, with subordinate chalcopyrite and trace galena, sphalerite, gold and silver which is generally hosted by a carbonate-quartz-chlorite gangue. Other minerals include covellite, tetrahedrite, red and specular hematite, sericite, jasper, garnet, rutile, sphene, barite, gypsum and possible arsenopyrite (Ray et al., 1991). Minor graphite is present, particularly along some fault zones. The orebodies are characterized by white to pale cream carbonate that includes calcite, ankerite and dolomite. The mineralized younger ankerite-dolomite alteration. The silicified rocks vary from grey to pzones and the adjacent barren marble may contain small amounts of red, podiform jasper that may be partially replaced by pyrite and rimmed with magnetite and chlorite. The orebodies are surrounded by irregular envelopes, up to 25 meters thick, of early silica and ale green to pale brown in color. Silica can crosscut bedding or may selectively replace certain beds in the tuffaceous siltstones, resulting in alternating layers of unaltered and silicified rocks. Where complete silicification has occurred, extensive zones of massive chert-like rock are formed. To summarize, the NW Zone appears to comprise a number of pyritic mantos, chimneys and irregular ore-bodies that have structural and stratigraphic-lithologic controls."

WORK HISTORY

Exploration in the area dates back to the early 1900’s when the Iskut Mining Company completed work on Johnny Mountain. During the early 1960’s, Newmont Mining Corp. of Canada Ltd. explored the area northwest of Newmont Lake just north of the McLymont property.

In 1980 the Warrior claims were staked by Dupont Canada Explorations Ltd., which covered ground now within the McLymont property boundary. Exploration on the property consisted of mapping, geochemistry and geophysics.

In 1983 Dupont optioned the property to Skyline Explorations Ltd. and Placer Development Ltd. The focus of exploration was narrow, high grade, quartz-pyrite- chalcopyrite veins. The claims were allowed to lapse in 1986 at which time Gulf staked the McLymont claims.

Gulf completed numerous exploration programs on the property from 1986 until 1990. Work included soil geochemical surveys, Mag and VLF surveys, mapping, trenching, road building and diamond drilling. To date approximately 60,000 feet of drilling has been completed on the property. The bulk of the drilling was used to delineate mineralization within the Northwest Zone.

Because of the work completed by Gulf two mineralized zones were evaluated. The Camp Zone, within the area first explored by Skyline and Placer, was the first zone drilled by Gulf. Mineralization consisted of gold in quartz-pyrite veins. The veins can be very high grade but tend to be narrow and discontinuous. Property wide exploration in 1987 led to the discovery of the Northwest Zone. Mineralization within the Northwest Zone consists of vein-like and replacement bodies of pyrite and magnetite with gold. Previous workers have suggested the zone may represent a gold rich retrograde skarn deposit.

In addition to the two main exploration targets two other zones, the Black Bear/Gorge Zone and the Valentine Zone, were identified but remained early stage targets.

During the summer of 2000, Pamicon Developments Ltd., on behalf of Gulf Minerals, conducted a small exploration program on the McLymont property. Fieldwork focused on the lesser explored Black Bear / Gorge Zone. 43 soil samples were collected.

A 2004 airborne magnetic survey by McLymont Mines Inc. consisted of a total of 580 kilometres and in 2005 an airborne magnetic survey consisted of a total of 1144 kilometres (Assessment Report 27582 and 27996). The results from an airborne magnetic survey completed over a portion of the Newmont Lake Property during the summer of 2005 (Press Release dated April 5, 2006) exhibited geophysical signatures characteristic of alkalic porphyry copper-gold centres. Romios Gold Exploration Inc. completed a 3D IP survey over the Northwest Zone, Grid 2 and the Ken Zone. Romios also completed a single diamond drill hole on the Black Bear Zone,

In 2005, consulting geologist Gerry Ray spent 16 days examining and mapping some prospective parts of the Newmont Lake claim block held by Romios Gold Resources Inc (Assessment Report 29085). Two field days were spent completing a reconnaissance-mapping traverse along the McLymont Fault that extended from the North Grid zone in the northeast down to the northwest zone in the extreme southwest.

In 2006, Romios' completed a program consisting of diamond drilling, a ground 3D induced polarization survey (IP), prospecting and the logging and sampling of diamond drill hole R-05-01 (from 2005). The drilling program was designed to expand the known gold/copper resource at the northwest zone and to test a 3D induced polarization (IP) anomaly located 500 metres northeast of the NW zone that was identified in a ground geophysical survey in 2005 (Press Release dated January 10, 2006). Ten 10 short holes (holes R-06-01 through R-06-10) totaling 770.8 metres were completed (Romios Gold Resource, Press Release, September 27, 2006). Romios tested the northwest zone one with five core holes from a common drill pad, DDH-06 to 10, significant widths of mineralization occurred in Holes 07 and 10.

In 2007, Romios announced a National Instrument 43-101 Inferred Resource on the Northwest Zone of 1,406,000 tonnes grading approximately 4.43 grams per tonne gold, 0.22 per cent copper, and 6.4 grams per tonne silver, or a gold equivalent grade (gold equivalent) of 5.16 grams per tonne Romios Gold Resources, News Release, March 27, 2007). Using a base case gold equivalent cut-off grade of 2.0 grams per tonne gold equivalent, this equated to an in-situ metal content of 6220 tonnes gold, 3,080,000 tonnes of copper and 9050 tonnes of silver at the time the calculations were carried out.

In 2008 Romios Gold Exploration Inc. completed 11 NQ-size, helicopter-assisted diamond-drill holes, totalling 3642.3 meters on the Northwest Zone (Assessment Report 30749). Approximately 659-line kilometres of helicopter-borne Electro Magnetic (EM or conductivity) and Magnetic survey over approximately 7855 hectares of newly staked claims to the east of the main graben, abutting 2007 airborne geophysical coverage over the graben. A total of 895 reconnaissance soil samples were taken at 50 metre intervals along the 250-metre spaced grid lines. Geological mapping, prospecting and geochemical rock sampling was carried out with a focus on the newly staked, wholly owned claims to the east of the main graben. Additional mineral showings were identified, and a total of 50 geochemical rock samples were collected. Approximately 17.625 kilometres of IP survey, 7.7 kilometres of TDEM and 48.2 kilometres of Magnetics were completed during the 2008 summer program over the Northwest, Black Bear and Everest zones (Assessment Report 30749).

In 2009 season, Romios Gold drilled four (4) NQ and HQ size, helicopter-assisted diamond-drill holes, totalling 399.3 meters, on the Lower Northwest Zone (Assessment Report 31506).

Over the 2010 season, mapping, prospecting and geochemical rock sampling were completed over the Dirk, Ridge and Telena showings. In total, 62 grab and chip samples of bornite and chalcopyrite bearing copper-gold mineralization were collected. Assessment Report 32050).

In 2011, Romios completed four diamond drill holes on the Dirk property totalling 743 metres (Press Release, Romios Gold Resources Inc, Sept. 9 and Oct. 19, 2011). Drilling at both the 72 (3 holes) and Telena (1 hole) zones encountered copper, gold and silver-bearing sulphides near surface in all of the drill holes within breccias and intrusions that appear to be genetically related to syenitic intrusions.

In 2012, Romios completed drilling, ground magnetics, audio-magnetotellurics (“AMT”) and borehole geophysics on the 72, Ken and Northwest Zones in addition to sample collection and general prospecting (Assessment Report 33620). Fifteen (15) NQ-size helicopter-assisted diamond-drill holes, totaling 2,616 metres, were drilled at the Northwest, 72, and Ken Zones on the Newmont Lake Project in 2012. Two drill holes were completed on the Northwest-Jazzman Zones, seven holes were drilled at the 72 Zone, and six drill holes were completed on the Ken Zone. Drill holes at the Northwest Zone and Jazzman both confirmed historical drill results and additionally indicate a new “Northwest Deep” mineralized horizon located approximately 75 metres below the Northwest Zone’s existing NI 43-101 Inferred Resource. The Northwest Deep horizon extends for 500 metres long by 60 metres wide and up to 40 metres thick, located below the Northwest Zone's principle resource area. JZ12-14 intersected a higher grade interval of 3.56 grams per tonne gold over 2.48 metres within 27.93 metres that assayed 0.35 gram per tonne gold. NW12-176 intersected 34.76 metres that assayed 0.31 gram per tonne gold (Assessment Report 33620).

In 2013, Ethos Geological completed work for Romios Gold resources on the Burgundy Ridge, 72 Zone (the Knob and Birthday Jim), Argent, Cannonball, the NW Block, the NE Block, and Iskut West (Assessment Report 34623).

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.

More than eighteen discrete magnetic anomalies (M1-M11) have been defined by the magnetic survey and more than half (9) are reported to be unexplained geologically. The ZTEM surveys have defined both conductive and resistive signatures that relate to bedrock geology on the property, to depths extending to greater than 1 to 2 kilometres. More than twelve prominent resistivity highs (R1-R9) were defined by the ZTEM survey. Most partially correlate with the more than eighteen magnetic anomalies and are interpreted to represent potential targets for porphyry-type magnetite-enriched potassic alteration. Fewer than six prominent resistivity lows (Z1-Z4) were defined and were reported to be for the most part longer, lineament-like conductive zones that lack magnetic signatures.

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 were taken and 26 stream silt samples were also collected. The focus of the 2014 program was to review the results from the 2013 exploration programs, included the investigation of numerous air-borne electromagnetic (ZTEM) and aeromagnetic airborne geophysical anomalies and to investigate the results from the prospecting and sampling program. Areas of priority included: Burgundy Ridge, Trek (104G) and numerous geologically unexplained ZTEM and magnetic geophysical anomalies.

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).

No work was reported for 2016 or 2017.

n 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 which also 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 three survey blocks cover a variety of copper-gold-silver targets including skarns, mantos and porphyry-style occurrences (for further details on the various mineralized targets see Romios' news release dated January 31, 2018).

Also in at this time, Romios completed a program of surface sampling and six reverse circulation drill holes on the property. Two holes, totalling 171 metres, were completed on the Northwest zone and yielded a near surface intercept of 26.44 grams per tonne gold, 21.35 grams per tonne silver and 0.21 per cent copper over 14.10 metres (Boyd, T. (2019-02-04): Independent Technical Report - Newmont Lake Property).

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

In 2019, Crystal Lake Mining Corp conducted a drill program, on the Burgundy Ridge prospect area (104B 325) and the Northwest deposit. They also conducted extensive grassroots exploration. Crystal Lake sampled and mapped the Cuba-Thumper trend along its 2.5 to 3.2 kilometre length. This trend is found between the Cuba prospects (104B 334 and 440) in the north and Thumper (104B 445) to the south. The trend is characterized by a high-grade high-grade silver-zinc-copper-lead barite system. Several new showings were documented in the "Chachi Corridor" (Crystal Lake Mining Corporation, News Release, October 10, 2019).

On Aug 12, 2019 Crystal Lake Mining had recovered an extensive amount of historic boxes of core on their Newomnt Property and an ongoing relogging and resampling program has yielded encouraging results, including 28.7 grams per tonne gold and 3.65 grams per tonne silver over 0.9 metres (207.6 to 298.5 metres) from 2008 drill hole R08-03 (Crystal Lake Mining Corp., News Release, August 12, 2019). Initial results from an IP survey indicated the presence of a chargeability anomaly in a prospective zone northeast of the Northwest Gold zone. New drilling was about to commence on the zone.

In September 2019 it was reported by Cystal Lake that drill intersections provided evidence of a thick unit of unusually high-grade gold mineralization within a broad envelop of continuous low-grade gold mineralization. This was reported to indicates a in width and grade in areas where previous models indicate a narrowing. The second of three drill holes, building on the northern extension of the Northwest zone, intersected 15.11 grams per tonne gold over 8.03 metres (106.32 metres to 114.35 metres), including 76 grams per tonne gold over 1 metre, in addition to an even shallower high-grade intercept of 7.6 grams per tonne gold, 23.1 grams per tonne silver and 1.03 per cent copper over 5.30 metres starting just 82 metres downhole, including 26.1 grams per tonne gold over 1.3 metres (Crystal Lake Mining Corp., News Release, September 18, 2019).
