SICKLE-SOFIA PROPERTY

Property Background Information

The Sickle-Sofia Property is situated in the Toodoggone District, a mineral exploration district renowned for a number of intrusion-related, high-grade, low-sulphidation epithermal gold and silver (Shasta, Baker, Lawyers) deposits and former producers, high-sulphidation gold and silver deposits (Albert's Hump), and copper-gold porphyry mines and deposits (Kemess South Mine, Kemess North, Pine).

Portions of the Sickle-Sofia Property were initially staked in 1999 and today the property consists of 25 contiguous mineral claims covering 9,077 hectares. The property has received over $1.5 million in exploration expenditures to date. Previous exploration work consisted of geological mapping, prospecting, property-wide grid-based rock and soil geochemistry, multi-array airborne geophysics, ground magnetic and IP surveys, and 3,323 metres of diamond drilling in 24 holes on the low-sulphidation, epithermal Quartz Lake vein system.
 
A total of 8 mineralized epithermal gold showings and corresponding gold-in-rock and soil anomalies and a broad, untested porphyry copper-gold, Kemess-style target (Sofia Zone) have been identified on the Sickle-Sofia Property. Only 1 gold target (Quartz Lake) has been drill tested to date. BCGold intends to conduct a $1.5 million exploration program entailing 30 line-km of infill Induced Polarization geophysics and 3,000 metres of diamond drilling focused primarily on the Sofia porphyry copper-gold target and two epithermal gold targets. The diamond drill and field crews are in place for this work, scheduled to commence in late June 2007.

Exploration Targets

A multi-partner, multi-parameter helicopter-borne geophysical survey performed in 2003 over the Toodoggone district outlined a significant circular 6 km magnetic-high anomaly within the Sickle-Sofia area. This magnetic signature also has a 2 km magnetic-low within the larger magnetic-high, which corresponds to a potassium-high and a thorium-potassium-ratio-low in its centre. The overall shape of this large 6 km geophysical signature is similar to a slightly elongated doughnut with a magnetic-low feature in the middle. On the ground, this magnetic-low corresponds to the geologically mapped and spectrographically confirmed area of high-sulphidation alteration. This high-sulphidation alteration was subsequently dated as being coeval with the local Jock Creek intrusion that hosts porphyry-style mineralization. The 2 km core of the geophysical feature is believed to be a magnetite destructive zone associated with a porphyry-style system.

Low-sulphidation epithermal style gold and silver mineralization on the Sickle-Sofia property is present at the North, Quartz Lake, Griz and Sickle vein systems. The Quartz Lake (A to B) veins have undergone the most intense exploration with surface chip/channel sampling followed by diamond drilling. High-sulphidation style alteration is present at the Alunite Ridge, BS Gold and Alexandra showings. The Sofia porphyry showing consists of potassically altered quartz monzonite intruding a mafic volcanic flow.

In 2006, a ground IP-resistivity and magnetic survey over the lower, glaciofluvial covered portion of the Sofia copper-gold porphyry target outlined a north trending chargeability anomaly of greater than 40 ms measuring 1.1 kilometre by 1.8 kilometres. This IP chargeability anomaly is flanked by magnetic fluctuations and significant copper-in-soil geochemical anomalies. The IP anomaly remains open towards the northeast and southwest, and is interpreted to represent disseminated sulphide within an intrusive. The Sofia porphyry target has never been drill tested and is considered the highest priority exploration target on the Sickle-Sofia property.
