Mt. Polley Area Properties
Overview
The Mt. Polley Area properties are made up of the following claims blocks; the Lloyd (which hosts the mineralized Boundary Zone), Nordik/Buc, Calm/Morehead and October/Dome that total approximately 10,000 hectares. They are located adjacent to the Metals Imperial producing open-pit Mount Polley copper gold mine, 100 km northeast of Williams Lake, British Columbia.
Regional Geology
Valley High's claims are located in the "Quesnel Trough" which is about 30 km wide and is fault bounded on the west by Paleozoic rocks of the Cache Creek Group and the east by the terrains of the Omineca Belt. The central area consists largely of a number of volcanic and sub-volcanic centers of predominantly alkalic composition of the Triassic Nicola Group. Numerous alkalic intrusive stocks are thought to be related to these volcanic centers in both age and composition. The area contains a number of gold and copper-gold porphyry deposits, possibly due to the presence of strong, deep-seated, regional scale structures and associated with alkalic intrusives.
In the immediate area, the largest known deposits are those at the Mount Polley Mine which is located immediately south of the Lloyd claims in the same intrusive host rock complex. The skarn hosted QR Gold Mine is located north of Quesnel River, to the northwest of the Valley High claims. Other significant gold copper deposits within the Quesnelia Belt include: Highand Valley, Gibraltar, Afton-Ajax Copper Mountain, and Mount Milligan.
Local Geology
The Mt. Polley Area properties are predominantly covered by a blanket of glacial till, which complicates geological interpretation in the area; bedrock is very poorly exposed. On the Lloyd claim where most prior work has been focussed, rock types are basic to intermediate varieties of volcanic breccias, tuffs, flows and minor epiclastic rocks, in part post mineral, as well as intrusive rocks potentially associated with mineralization. Intrusive rock outcrops have been located in the central part of the claim as well as near its southern boundary. Airborne magnetic and radiometric surveys indicate that the intrusive, which contains magnetite and has a positive radiometric response due to the K-feldspar content, may extend more than 1.0 km north onto the Lloyd claims. A detailed ground IP survey (completed in 2006) suggests that a number of chargeability anomalies underlie the post mineral volcanic rock sequence at reasonably shallow depths.
The alteration seen at the Lloyd claim includes pervasive salmon pink-coloured potassic feldspar and also chlorite-epidote which usually occurs along fractures. Strong K-feldspar alteration, brecciation and disseminated (1-10%) pyrite and minor finely disseminated chalcopyrite were noted in intrusive rocks below volcanic cover in drilling completed in 2000.
The other claim groups have received much less previous exploration and so knowledge of their local geology is less understood, however none the less prospective.
Boundary Zone
The geology at the Boundary Zone, as based on diamond drill logs, comprises predominantly intrusive rocks, mainly monzonites and occasional feldspar porphyries, post mineral pyroxenite porphyry dykes, and overlying post mineral volcanics. The intrusives appear to be irregular bodies, possibly hypabyssal, are variably potassically altered, and are cross cut by zones of brecciation, which are associated with magnetite-chlorite- calcite alteration, and copper-gold mineralization.
The Boundary Zone was discovered in 1993 and was extensively drilled between 1994 and 1997, prior to being acquired by Valley High Ventures in 2005. In 2006, Valley High completed additional diamond drilling, with intersections highlighted by hole L06-7 which cut 21m at 2.01%Cu +0.68g/t Au, and hole L06-9 which hit 20.4m at 0.87%Cu + 0.39g/t Au. In July 2008, Imperial Metals reported that exploration drilling on its portion of the Zone encountered high grade copper gold mineralization; Hole ND 08-42 returned 32.3 m @ 1.43% copper + 1.47 g/t gold and ND 08-44 returned 22.3 m at 1.56% copper + 1.21 g/t gold, with both holes being drilled within 100m of the property boundary.
About Imperial Metals Mount Polley Mine
According to an Imperial Metals press release dated March 31 2008, Proven and Probable reserves at the Mt Polley mine as at January 1st 2008 were 55,600,000 tones at 0.357%Cu + 0.298g/tAu + 0.66g/t Ag using metal prices of US$1.80/lb Cu, US$750/oz Au, and US$10/oz Ag. In their 2007 annual information form, Imperial reported that the operation milled 6,444,112 tonnes of ore at head grades of 0.461%Cu + 0.242g/tAu.
According to information available on the Imperial Metals website, exploration for additional resources at Mount Polley will be focused on the Springer, C2, Boundary, Area 9, Southeast, Pond, Ace, Skid and 92(Quarry) zones.
Valley High Exploration Targets
Four of Imperial Metal's exploration targets, the 92(Quarry), Skid, Southeast and Area 9 zones are located in proximity to Valley High claim boundaries. In addition, and as described outlined below, the Lloyd claims north of the Boundary Zone, have several high priority IP targets that require drill testing. As outlined in the attached sketch.
