The Jazzman (and Northwest (NW) zone is a Volcanic Massive Sulphide (VMS) zone according to Romios Gold. The massive sulphides are host to gold, copper and silver. The zone is hosted in andesitic volcanic rocks of the Carboniferous to Permian Stikine Assemblage. To the northwest of the NW/Jazzman zone is a large intrusive syenite zone and a smaller region of limestone.
The Jazzman area is underlain by volcanic and sedimentary rocks, on the western margin of a large area of intrusive rocks. Rock types include sandstone, conglomerate, tuff and flows, and an interbedded horizon of crinoidal limestone. Folding and several northeast to northwest fault structures cross the area creating a more complex geological setting.
Drilling found that below the limestone horizon a pervasive silica-dolomite-sericite (?) alteration zone up to 200 metres thick has pervaded host rocks. Chlorite occurs as selvages and reaction rims adjacent to veinlets and breccia fragments. Pyrite occurs as ubiquitous disseminations, stringers, etc. Minor chalcopyrite and magnetite were also encountered. Other alterations encountered in core and on surface include ankerite (plus or minus barite) pervading country rock and as veinlets; epidote, hematite and jasper were also encountered.
The best mineralization from drilling was encountered in hole J-90-2 with several 1 metre samples assaying high in gold including one intersection of 11.38 grams per tonne gold (Assessment Report 21152). These values occur within or below the main silica alteration zone, with higher gold values associated with pyrite.
The crinoidal limestone that occurs at the Northwest zone (104B 281) to the southwest, though similar, is thought to be a different unit, at a stratigraphically and structurally lower position.
2012 drill holes at the Northwest and Jazzman zones 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. Jazzman drillhole 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 (Assessment Report 33620).
The 2013 ZTEM low resistivity area Z3 is a moderate to large (2.5 by 5 kilometre), northeast trending zone. It is a shallow buried and strengthens with depth, weak to non-magnetic and poorly conductive zone in southeastern area of block. It is geologically unexplained and occurs in andesitic volcanics and monzonite. It coincides spatially with Newmont Lake Graben and THE Jazzman and Northwest VMS occurrences.
Drilling, CSAMT (controlled-source audio-magneto-telluric) and surface-to-borehole resistivity surveys at the Northwest-Jazzman massive sulphide zones have indicated an area of high conductivity at 350 metres depth, immediately to the north of the Northwest zone. Drill hole JZ12-14, drilled near this area, encountered numerous sulphide-bearing horizons throughout its entire length from zero to 715 metres downhole (locally ranging up to 25-per-cent pyrite by volume over 1.0 metre).
Structural and orthophoto interpretation work was performed on the Gab 5 to 10 claim area in 1987 on behalf of Northwest Gold Syndicate. A 105.67 kilometre airborne magnetic and electromagnetic survey was completed. Minor prospecting occurred on the Gab 7 and 9 and Ken zone.
In 1988, Jazzman Resouces Inc drilled 5 BQ diamond drilholes totalling 854.3 metres. During 1990, Jazzman completed four drill holes from one set-up on the Gab 9 claim in an area believed to be the on-strike projection of the Northwest Zone. A fifth drill hole was collared approximately 125 metres to the north to test the strike extension.
The NW Zone and the Camp Zone were the focus of extensive drill testing by Gulf between 1987 and 1990 and the Ken Zone was tested by a limited drill program in 1988 by Pezgold Resources 27996
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 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 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 NW 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 NW Zone with five core holes from a common drill pad, DDH-06 to 10, significant widths of mineralization occurred in Holes 07 and 10.
A 3D induced polarization (I.P.) anomaly southwest of the Jazzman Zone was tested by three holes, DDH06-01, DDH06-02 and DDH06-03, all drilled from the same pad. The IP anomaly identified by SJ Geophysics is attributed to weakly graphitic and silicified black shale unrelated to the sulphide mineralization of the Jazzman Zone Two drill holes DDH06-02 and DDH06-03 intersected a marble with both weak sulphide and jasper mineralization. Two other drill holes were attempted closer to the Jazzman Zone but failed to penetrate the glacial till
In 2007, A total of nine (9) BTW and NQ-size, helicopter-assisted diamond-drill holes, totalling 1,214.6 meters, were drilled within the Newmont Lake property, on the Ken, 2Bad, Bridget, RNT, Vera and Northwest zones (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 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 metres, 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.
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.
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 the 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 is reported for 2016 or 2017.
