Capsule Geology

The area of the Black Bear and Gorge zones are underlain by Devonian to Permian marine sedimentary and volcanic rocks of the Stikine Assemblage.

The Black Bear and Gorge are two adjacent zones that lie immediately north of the Camp Zone covering 0.5 square kilometres of silicified gossanous rocks elongated in a north south direction. The Black Bear zone is described as pyritic, cherty-silica alteration overprinting a package of mostly fine-grained sedimentary and tuffaceous rocks. Banded cherts are hydrothermal in origin related to the nearby Camp Stock. The fine-grained pyritic (?) cherty-silica rich rocks are generally light to very dark grey of andesitic to dacitic composition. Two trenches in the Gorge Zone exposed trace sphalerite and chalcopyrite. Core logging of the Black Bear Zone identified the previously described pyritic alteration is mainly magnetite with subordinate pyrrhotite alteration. Both zones have been mapped and soil sampled.

Consulting geologist Gerald Ray surmised there could be a strong possibility that the pyritic silica is hydrothermal in origin, and that it may be genetically and temporally related to the nearby gold-bearing Camp Stock. Thus, the silica may represent a relatively barren cap that overlies either a gold or copper bearing ore body (Assessment Report 29085). The only drilling has been the single drill hole completed by Romios Gold Exploration Inc in 2005 but not logged or sampled prior to 2006. Several intersections yielded greater than 1 per cent zinc. The highest was 1.99 per cent zinc over 1.42 metres (Assessment Report 30449). Drill hole R-05-01 tested only a limited stratigraphic section of the Black Bear Zone. Gold, copper and silver assay values from drill hole R-05-01 samples are not considered significant. And it was determined that the hole did not reach the margin of the Camp Stock where an ore body might occur.

In 2013, electromagnetic (ZTEM) and aeromagnetic geophysical surveys by Romios Gold Resources defined priority geophysical targets around the Camp/Black Bear-Gorge occurrences, including Magnetic targets M8, M8' and M9, Resistive target R8 and Conductive target Z1, along with its central north-trending conductive lineament (Figure 20. Assessment Report 35016).

Ray summarized (Assessment Report 29085): "...the Black Bear and Gorge Zones represent a very large area of rusty-weathering pyritic cherty-silica. It is uncertain whether the silica-pyrite is sedimentary-volcanic syngenetic in origin or if it represents hydrothermal alteration, perhaps genetically related to the adjacent Camp Stock. Apart from trace sporadic signs of some base and precious metals, most of the surface exposures appear to be barren. However, since the Camp Stock hosts Au-bearing quartz veins of the Camp Zone, it is possible that the pyrite-silica represents a barren cap overlying a gold or copper bearing ore body."

WORK HISTORY

In 2005, Romios completed a single diamond drill hole on the Black Bear Zone. The hole was drilled, but not logged or sampled, in 2005 (Assessment Report 29085). The purpose of the hole was to intersect the Black Bear Zone pyritic silica adjacent to the northern margin of the auriferous Camp stock. The hole was driven to a depth of 240 metres (787 feet) but it was not logged or sampled in detail. The hole reportedly intersected variably silicified and pyritized metavolcanics but did not reach the margin of the Camp Stock.

The work undertaken by Romios in 2006 focused on four of the 22 known mineral showings on the Newmont Lake property, namely, Camp Zone, Black Bear Zone, Jazzman, and Northwest Zone. The Black Bear Zone was investigated in 2006 by logging and sampling core from diamond drill hole R-05-01 drilled in 2005 (Assessment Report 30449).

An approximately 65.5 square kilometre area over the center portion of the property was covered by a helicopter-borne Electro Magnetic (EM or conductivity) and Magnetic survey. Ground Spectral IP/Resistivity (IP) and Magnetics survey were also conducted on the Northwest, Vera, RNT, Ken and Black Bear Zones, with approximately 19.7 kilometres of IP survey and 40.2 kilometres of Magnetics completed during the 2007 summer program (Assessment Report 30449).

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 gird 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 km of TDEM and 48.2 km of Magnetics were completed during the 2008 summer program over the Northwest, Black Bear and Everest zones (Assessment Report 30749).

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), Camp (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 2018, Romios Gold Resources Inc successfully completed an airborne magnetic and VTEM-Terrain Time Domain electromagnetic survey over three of the Company's most prospective exploration targets on its Newmont Lake property. The three survey blocks covered are referred to as the Northwest Zone, Ken Zone and the Dirk claims. VTEM Anomaly #3 occurs along the southeastern margin of the Northwest Survey block. It is about 1.2 kilometres by 1 kilometre in size and extends to, and presumably beyond to the Camp prospect (104B 126). Two predominant mineral occurrences are known from within this anomalous area, the Black Bear and the Camp Zone and 2 smaller zones known as the Gorge and Valentine (Figure 15, Assessment Report 37492). Given the sulphide-magnetite-silica zone found at the Black Bear-Gorge area, the anomalous soil values, and the possibility that it reflects the cap over a porphyry-style copper-gold system the VTEM low-resistivity anomaly is of interest.

In late 2018, Crystal Lake Mining entered into an agreement with Romios Gold Resources Inc. for an option to acquire a 100 per cent interest in the 436 square kilometre Newmont Lake Project from Romios Gold.

See Burgundy (104B 325) and Northwest (104B 281) for details of the related historical work and work that is ongoing in 2019 to date.
