Troymet Identifies Extension of Discovery Horizon at McClarty Lake Project
| ||April 11, 2011 - Troymet Exploration Corp. (TSXV:TYE) ("Troymet" or the "Company") is pleased to report that its recently completed reconnaissance drilling program at McClarty Lake identified the northern extension of the horizon that hosts the Discovery zone. |
The newly identified Mac zone was selected for drilling following the completion of a pulse electromagnetic (PEM) survey of a VTEM conductor trend. The results are significant as they indicate the presence of a +2,000-metre long stratigraphic horizon that carries base metal mineralization in the two locales, where tested. The recognition of a productive, base metal mineralized horizon extending through Troymet's 100% owned claims significantly increases the possibility of a significant VMS discovery on the Company's 100% owned ground. Volcanogenic massive sulphide ("VMS") deposits form at specific times on specific stratigraphic horizons, in marine extensional basins associated with volcanic arcs. As an example "In the Snow Lake camp the Lalor deposit is similar to other massive sulphide deposits in the Chisel sequence (Chisel, Lake, Ghost Lake, Chisel North and Photo Lake), and lies along the same stratigraphic horizon as the Chisel Lake and Chisel North deposits." (Reference: Technical Report on the Lalor Lake Deposit by Scott Wilson Mining for HudBay Minerals Inc., 2008).
Three holes (1,156 metres) tested the Mac EM conductor over a 300-metre strike length (see drill hole compilation and Mac conductor drill plan maps at McClarty - Maps & Photos page). Following completion of the first hole it was quickly recognized that it had been drilled down-dip and the azimuth of holes two and three were changed accordingly. This was the first drilling ever conducted in the area. Multiple anomalous zones are present in all three holes; a summary is as follows:
MAC-11-01 (120° azimuth/-75° dip) intersected an intrusive margin complex (IMC) to 178 metes depth followed by mafic volcanics to 413 metres (end of hole). The IMC is described as a heterogeneous zone characterized by xenoliths (remnant rafts) of mafic volcanics and minor metasediments within a granitic to tonalitic intrusion. Several 1-2 metre wide pyritic zones (3-5% pyrite ± graphite ± quartz veining) hosted within volcanic xenoliths returned anomalous copper values up to 1,202 ppm (0.12%) Cu.
MAC-11-02 was collared 100 metres grid north and drilled in the opposite direction at 290° azimuth and -50° dip. The hole intersected mafic volcanics and gabbro to 159 metres followed by felsic volcaniclastics to 230 metres. The felsic volcanic horizon hosts a number of 1- to 4-metre wide, finely laminated pyritic zones containing up to 15% pyrite ± graphite, returning anomalous copper (up to 294 ppm) and zinc up to 196 ppm). Xenolithic tonalite intrusive predominated for the remainder of the hole, characterized by xenoliths of mafic volcanics and zones of strong sulphide replacement. The 1- to 2-metre wide sulphidic zones host up to 10% pyrite, 30% pyrrhotite and <1% chalcopyrite, returning anomalous copper and zinc values up to 1,038 ppm (0.10%) Cu and 361 ppm Zn.
MAC-11-03 was collared 100 metres grid south of MAC-11-01 and drilled at 290° azimuth and -60° dip. The hole intersected mafic volcanics to 184 metres depth followed by xenolithic granodiorite intrusive to 371 metres (end of hole). The granodiorite is characterized as hosting abundant volcanic xenoliths and zones of strong sulphide replacement. The 2- to 3-metre wide sulphidic zones host up to 20% pyrite, <1% sphalerite and trace chalcopyrite, returning anomalous copper and zinc values up to 281 ppm Cu and 4,341 ppm (0.43%) Zn.
Management is pleased with the results of the first-pass reconnaissance drilling program, which has extended the productive volcanic horizon over a strike length in excess of two kilometres. The presence of volcanic xenoliths and strongly sulphidized zones within the various intrusive bodies suggests that the volcanic horizon, where intersected, has been partially digested. There is potential for uninterrupted extensions of the mineralized volcanics along strike and to depth.
Given the absence of outcrop in this region of the Snow Lake camp, the location and orientation of initial drill holes were based entirely on the interpretation of various geophysical surveys. A review of the PEM survey with representatives of Crone Geophysics concluded that the orientation of the PEM survey was not optimal, and that a survey of the VTEM conductor trend from loops laid out east of the trend could identify additional conductors along the productive horizon. The PEM conductor/Mac zone remains open to the north and south, as well as to depth. Further PEM surveys and diamond drilling are required to adequately explore the Mac mineralized zone.
The McClarty Lake property is located near Snow Lake, Manitoba and lies ~45 kilometres south of HudBay's Chisel North and Lalor volcanogenic massive sulphide (VMS) deposits. The property comprises three claims (MAC-1, MAC-2 & MAC-3; 344 hectares) owned 100% by Troymet and two claims owned (DYC3606 & DOL78; 252 hectares) owned 60% by Troymet and 40% by HudBay ("option claims"). HudBay is earning an additional 20% interest in the option claims by spending $750,000 on exploration by June 5, 2011. A diamond drilling program in the Discovery zone area is currently underway.
