Highlights

The Redhill project is prospective for gold-copper-zinc volcanogenic massive sulphide ("VMS") and structurally controlled gold mineralization. The volcanic sequence of the Redhill sector is exposed in a 5 km wide, NNW-striking thrust slice over a distance of at least 20 km. The geology is interpreted to be chemically analogous and age equivalent to the Permo-Triassic age Kutcho Assemblage that hosts the Kutcho Creek Cu-Pb-Zn-Ag VMS deposit in northern British Columbia. New exploration and targeting concepts have identified new drill targets in the Alpha, Beta and Alpha South zones.

Current Status

Troymet has been granted a multi-year permit for its diamond drilling program on the Alpha and Beta zones. The Company may undertake additional EM surveys on the Alpha zone prior to drilling to test for extensions to the prospective TEM conductors and to follow up copper, zinc and gold soil anomalies, some of which are associated with historic prospective volcanic sequences..

Previous Work

The Red Hill property has been intermittently explored for porphyry copper-molybdenum mineralization, magnetite copper-gold skarn mineralization, and copper-zinc-silver-gold volcanogenic massive sulphide (VMS) deposits. Most of the modern exploration was carried out by Noranda, Rea Gold, BP Selco, Cominco, Teck Corporation and Avalon Ventures Ltd.

BP Selco conducted limited drilling on the property in 1983-84. Drill hole S83-4 intersected stringer zone mineralization on the historic Feedlot (Beta) zone, returning a best intersection of 2.54% copper, 2.78% zinc, 77.0 g/t silver, and 0.37 g/t gold over 7.75 metres (BC ARIS Report #28371). Drilling by Rea Gold from 1985 to 1988 included 6 core holes and 9 percussion holes. Teck Corporation drilled 22 core holes in 1998 and 2001, primarily concentrating on the Feedlot (Beta) zone. In 2005, Avalon Ventures drilled 3 core holes on the Feedlot (Beta) zone and 3 on the Redhill (Alpha) zone. Avalon contracted a TEM survey over the Redhill (Alpha) zone in 2006, identifying 11 EM conductors over a ~600 m x 1,100 m area. Borehole EM surveys were also conducted on Avalon's 3 core holes at Redhill, detecting an off-hole TEM conductor in RH-05-23. Avalon subsequently drilled 4 holes to test the off-hole conductor. RH-06-25 intersected massive sulphide mineralization returning 10.15% copper, 5.45% zinc, 1.41 g/t gold and >30 ppm silver over 1.74 m. A borehole pulse EM survey on RH-06-25 identified a new, strong off-hole conductor in the vicinity, which to date has not been tested by drilling. 

Alpha & Alpha South Zones

The Alpha zone encompasses a 2.0 km x 2.5 km sequence of felsic to intermediate volcanics that include the historic Redhill zone as well as an extensive area of untested copper-zinc-silver soil anomalies. The alteration and mineralization within the volcanic sequence is interpreted to represent a stringer zone in the footwall of a VMS exhalative system. The Alpha South zone is centred on a prominent hill approximately 600 metres south of the Alpha zone.

A primary target at Alpha is an untested, off-hole pulse EM conductor in the vicinity of 2006 diamond drill hole RH-06-25, which intersected massive sulphide mineralization grading 10.15% copper, 5.45% zinc, 1.41 g/t gold, and >30.0 g/t silver over 1.74 m. Troymet has confirmed the mineralized intersection with visual inspection and re-assaying the core. Troymet retained Frontier Geosciences Inc. to review the results of the surface TEM survey conducted on the Alpha zone in 2005 (October 7, 2015 news release). Frontier’s review determined that the gold-rich, high-grade copper intercepts in holes RH05-23 and RH06-25 were not detected by the TEM survey, indicating that two separate zones exist in this area. Consequently, the intercepts in these holes may be part of a deeper, high-grade zone(s) of VMS mineralization. In addition, historical drillng was concentrated in the centre of the TEM grid; however, the stronger TEM responses occur in the southeastern and northwestern areas of the grid and have not yet been tested by drilling. 

Troymet completed a B-horizon soil sampling program over the Alpha and Alpha South zones in September 2015 (October 20, 2015 and October 29, 2015 news releases). At the Alpha zone, a strong copper response is noted in the vicinty of holes RH05-23 and RH06-25. There is also a strong copper response associated with EM conductors PT1 and PT2, and down slope to the southwest of conductor PT1. The association of EM conductors with copper-in-soil anomalies indicates there are additional prospective sequences that have not yet been mapped or recognized. In contrast to copper, the stronger gold values occur, consistently, line-to-line over a distance >1,000 m. The gold anomaly may be reflecting an unrecognized prospective volcanic sequence or it may be mapping a hitherto undiscovered mineralized structure.

The copper, zinc and gold anomalies at Alpha South lie ~1,200 m southwest of the Alpha zone anomalies. They appear to be separate and distinct trends related to separate structures or mineralized horizons. Troymet plans a mapping program to establish the geological and structural controls on the soil anomalies. No deep penetrating TEM surveys have been conducted on the Alpha South zone and as such it is unknown if there are EM conductors associated with the anomalies. Given the geological and structural similarities between the Alpha and Alpha South zones, it seems likely the controls on mineralization will be the same. However, it is possible the gold anomalies are controlled by a currently, unrecognized mineralized structure(s). Based on available records, only two percussion holes have been drilled on the Alpha South zone. Both were shallow (less than 85 m) angle holes that tested a small geochemical anomaly near an old adit. Hole S81-5 bottomed in mineralization, intersecting 0.48% zinc over 6.1 m.

Beta Zone

The Beta zone (historically called the Feedlot zone) encompasses a 2.5 km x 2.5 km sequence of felsic to intermediate volcanics, graphitic sediments, iron formation +/- locally laminated semi-massive to massive sulphides containing pyrrhotite +/- pyrite +/- minor chalcopyrite. Diamond drilling by BP Selco in 1983 reportedly intersected stringer zone mineralization in hole S83-4, grading 2.54% copper, 2.78% zinc, 77.0 g/t silver, and 0.37 g/t gold over 7.75 m. (BC ARIS Report #28371). There is no existing core from this hole for re-logging or confirmatory sampling. The Beta zone appears to stratigraphically overly the Alpha zone in the volcanic sequence. Numerous EM, IP/R and magnetic anomalies are present. Troymet is evaluating the geology, geochemistry and geophysical anomalies to identify drill targets.
