The Inza property is a copper-gold porphyry prospect located within the prolific Quesnel Trough in central British Columbia. It is situated approximately 54 km north northwest of Fort St. James and is road accessible by highway and by a series of logging roads to the western and eastern portions of the property. The property comprises 7,260 ha and is 100% owned by Strongbow Exploration. The Mount Milligan Deposit is located 40 km to the northeast while the recently discovered Kwanika deposit, owned by Serengeti Resources, is situated 87 km to the northwest.
Four phases of historic work have been conducted in this area.
• In 1990, Rio Algom collected 2,191 soil samples which produced three broad copper-molybdenum-gold soil geochemical anomalies coincident within a regional magnetic anomaly. The soil anomalies range in approximate size from 2,000 m by 2,000 m (Anomaly I) to 800 m by 800 m (Anomaly II). Bedrock mapping of the western part of the claims identified the host rocks to be predominantly Takla Group volcanics, locally intruded by monzonite porphyry. Prospecting in the area of the soil anomalies uncovered volcanic outcrop with 1-5% disseminated pyrite and pyrrhotite with trace chalcopyrite, as well as monzonite outcrop with sparse quartz veins containing trace molybdenum. Results returned weakly anomalous copper (525 ppm) and gold (199 ppb);
• In 1995, a small prospecting and soil sampling program was also conducted over the north-central part of the Inza claims, east of Rio Algom's soil anomalies. Although soil sampling was unsuccessful due to thick overburden, prospecting returned anomalous samples 2.5 g/t Au Au, 107 ppm Cu, 4016 ppm Zn, 3289 ppm As, collected from subcrop to outcrop gossanous andesite breccia, near altered intrusive monzonite;
• In 2008 government lake sediment sampling program identified several samples ranging from 51.9 to 136.8 ppm copper, which are significant anomalies for the area. These samples are situated downslope to the east of the historic soil (Anomaly I).
Strongbow has conducted two short prospecting programs on the property (2008 and 2009). Efforts were concentrated on prospecting along logging roads and skidder trails where new bedrock may be exposed. This work resulted in the collection of multiple rock samples, four of which came from an altered biotite-feldspar porphyry, identified along a new logging road and positioned along the southern margin of the larger historic soil anomaly. All four samples returned anomalous metal values, including 136 ppm to 9,450 ppm copper, background to 798 ppb gold and 34 ppm to 711 ppm molybdenum.
In 2009, Strongbow completed 11 line kilometres of Induced Potential (IP) surveying and 22 line kilometres of magnetic surveying, broadly coincident with the Rio Algom's historic soil Anomaly I. This survey focused only on the northern portion of the regional airborne magnetic anomaly that has a northwest-southeast extent of 9.0 km and a maximum width of 3.0 km. The ground magnetic data define a ring-shaped or moat-like feature which is postulated to be related to potassic or siliceous alteration that could have caused the destruction of magnetite within an intrusive-hosted porphyry system (and therefore formed the circular pattern of magnetic lows). The Cu-in-soil anomaly demonstrates a coincident relationship with respect to this circular magnetic low anomaly.
Chargeability anomalies identified in the IP survey are spatially related to the magnetic low anomalies. A broadly developed chargeable zone (> 20 v/Mv) measures approximately 2 km east-west and is open to the north and south beyond the extent of the 1.2 km tested. Resistivity anomalies are developed on all four lines but only demonstrate a coincident relationship with respect to chargeability anomalies on the two northern most lines. There also seems to be evidence for a broadening of a chargeability anomaly from south to north. Finally, the two northern most lines show evidence for chargeability anomalies extending to depth.
Proposed work in 2010 will include ground truthing the areas with coincident chargeability and resistivity anomalies, and evaluating the relationship these anomalies demonstrate to the magnetic lows. Strongbow's 2010 exploration programs are conducted under the supervision of David Gale, P.Geo.(BC/NT), Vice-President of Exploration for Strongbow and a qualified person under NI 43-101.
