Troymet Intersects Porphyry Style Mineralization on Key Project

May 9, 2011 - Troymet Exploration Corp. (TSXV:TYE) (“Troymet” or the “Company”) announces results from the winter reconnaissance diamond drilling program on its 100% owned Key project. The project is located 125 km southwest of Vanderhoof, BC, and immediately adjoins the Blackwater project of Richfield Ventures Corp. In total, 12 holes (1,576.8m) were drilled including five holes in the area of Good News Lake and four holes on the Crag Grid on the west side of the property. Three holes were lost in broken rubbly ground or in thick overburden.

The Company is pleased to report that drilling intersected highly anomalous porphyry style mineralization in five widely-spaced holes in the area of Good News Lake (Table 1; here and here;). A large porphyry target requiring significant additional drilling is indicated.

Individual holes carry copper or molybdenum +/- zinc, and locally weak to moderate silver and elevated to anomalous gold. The mineralization occurs in altered volcanics capping a 2.5 x 3.0 km multi-phase intrusive. Interpreted diatremes/breccia pipes lie within a distinct, weakly magnetic phase of the intrusive. Garnet alteration, breccias and semi-massive to massive pyrite and magnetite occur immediately south of Good News Lake. Induced polarization (IP) surveying has outlined a prominent anomaly with chargeabilities of 20 to 60 mv/v associated with the mineralization over a minimum of 1.2 km north-south and 3 km east-west. The IP indicates the presence of a large hydrothermal system with high sulphide content and may, in part, represent a pyritic halo. As well, layered sphalerite mineralization occurs along the contact of mafic tuffs and interbedded sediments on Tsacha Mountain, approximately 2.5 km to the north.

Drill holes Key-7, 8 and 9, drilled to test coincident IP and gold-in-soil anomalies along and adjacent to the GN Fault, intersected a similar sequence of felsic to intermediate tuffs that are variably magnetic, silicificed, pyritized (3-15%), sericitized and brecciated with stringer and quartz vein/veinlet stockworks. All three holes intersected locally anomalous mineralization and altered and pyritized rocks throughout their entire lengths. Holes Key-8 and 9 tested targets approximately 180m west and 200m south of Key-7, respectively.

  • Hole Key-7 intersected 312.7 m of significantly anomalous molybdenum along with intervals of anomalous to low-grade zinc mineralization, anomalous copper and narrow intervals of anomalous gold (Table 1), including:
    • 312.7m @ 0.02%MoS2
    • 45.5m @ 0.05% MoS2
    Select molybdenum-rich samples contained 0.04 to 0.13 ppm rhenium. Quartz-pyrite and quartz-pyrite-molybdenum-magnetite veins/veinlets are developed throughout the entire section and sphalerite with trace chalcopyrite occur locally. Alteration is present in narrow envelopes to the veins; however, where multi-phase veining is present the rock appears pervasively altered.
  • Hole Key-8 intersected several sections of anomalous to low-grade zinc mineralization, and anomalous silver, gold and lead, including:
    • 122.5m @ 452 ppm Zn & 0.012 g/t Au & 1.1 ppm Ag
    • 4.3m @ 0.114 g/t Au & 2.8 ppm Ag
  • Hole Key-9 intersected strongly anomalous zinc, silver, gold and lead mineralization, including:
    • 45.8m @ 0.01 g/t Au; 2.5 g/t Ag & 961 ppm Zn
    • 5.0m @ 0.05 g/t Au; 11.1 g/t Ag & 2279 ppm Zn

Hole Key-10, collared 2.2 km NE of Key-7, tested a coincident IP and copper-in-soil anomaly on the East Fault. It intersected silicified and pyritized (1-10%) alteration within felsic to intermediate volcanics with stringer quartz-pyrite-pyrrhotite veins/veinlets to 204.2 m. The zone also carries anomalous copper and tungsten.

Hole Key-12, drilled to test an IP anomaly, intersected monzonite intrusive with mafic dyking in the upper part of the hole. The monzonite carries disseminated pyrite (1-10%) throughout together with quartz-pyrite+/-chalcopyrite veins and stringers accompanied by anomalous copper values.

Hole Key-11 attempted to test one of the possible diatremes in the intrusive (September 16, 2010 news release) but was lost in thick overburden.

Four holes tested targets on the Crag grid located on the west side of the property. Holes Key-3 and 5 tested coincident induced polarization/gold-in-soil/surface gold targets, while holes Key-4 and 6 tested two VTEM targets. The VTEM anomalies appear to be associated with fault/breccia zones in felsic to intermediate volcanics with local vein/disseminated pyrite. The IP/gold-in-soil/surface gold targets comprise silicified and pyritised (trace to 1%) felsic to intermediate volcanics. No significant values were returned. Holes Key-1 and 2 were lost in broken, rubbly ground and did not reach target depth.

Troymet is currently mobilizing a field crew to the property to continue prospecting and sampling in unexplored areas of the large (8,854 ha) property. The Company has also contracted specialists in glacial till mapping and sampling to advise and guide the field program. To date, less than a third of the property has been explored in any detail.

Additional IP surveying and soil sampling are planned to delineate the extent of the porphyry system prior to resumption of diamond drilling. A number of drill targets in the area of Tsacha Mountain were inaccessible during the winter program due to terrain and weather, and are expected to be drilled this summer. Following receipt of all assays, the Company plans to schedule additional geophysical programs and diamond drilling.

Samples were assayed at ALS Chemex, Vancouver, BC, an ISO 9001:2000 accredited facility. On-site management of the drill program was provided by Casselman Geological Services Ltd.
