Size: 110 Claim, 2716.94 Hectares
Location: Dubuisson Township
Prospects: Copper, Silver and Gold
NI 43-101: N/A
Acquisition: Virginia (2006), Niogold (2006/2009)
The Siscoe East property is located 3 km north west of Val d’Or, QC and is situated between the historic Siscoe and Sullivan mines, which collectively have produced in excess of 2.1 million ounces of gold between 1930 and 1968, and hosts the historic Stabell Mine that produced 1,750 ounces of gold at an average grade of 0.27 oz/ton between 1935 and 1937. The property is underlain by the volcanic rocks of Lower Malartic Group to the northwest, and a regional granodiorite intrusive, known as the Bourlamaque Batholith, to the southeast. Alexandria completed a 2,750 m drilling programme on the property in 2006 and subsequently Niogold entered into a joint-venture agreement to earn 50% ownership of the property in 2008. Currently, Niogold is the chief operator on the property and recently concluded an exploration progromme in late 2009.
The Siscoe East property is situated within the Malartic group of mafic to ultramafic volcanic rocks north of the Cadillac Tectonic Zone (CTZ). The property is characterized by the contact between the mafic to ultra mafic volcanic rocks of the Dubuisson formation (Lower Malartic Group) and the multi-phased granodiorite – diorite Bourlamaque Batholith.
The Bourlamaque Batholoith covers a large portion of the southeast claims of the Siscoe East Property and is an important intrusive feature that characterizes a lot of the reigions unit within the Val d’Or region. In addition to hosting several large, multi-million ounce gold deposits, including the Beaufor, Ferdeber and Sullivan Mines, this large felsic intrusive unit has also acted as a crucial heat source for the regions hydrothermal alteration, and subsequent gold mineralization. Economic gold mineralization associated with the Bourlamaque Batholith occurs in several environments including: the margins of the batholith, within vein hosted shear-zones throughout the batholith and within sheared veins of satellite intrusive stocks.
Additionally, within this volcanic package, structurally controlled zones of chlorite-tremolite-actinolite characterize a sub-parallel shear zone to the CTZ know as the K-Shear Zone. This northwest trending fault extends from the historic Stabell Mine through the Sullivan and Siscoe mines and structurally controls gold mineralization at all three of these historic producing mines. Gold mineralization has been identified along the K-Shear Zone with drill results intersecting a narrow high-grade quartz-tourmaline vein that averaged 28.40 g/t Au over 1.1m within the Bourlamaque Batholith. The K-Shear Zone remains a top priority target at the Siscoe East property for future exploration.
HISTORICAL EXPLORATION Top
Historical exploration on the Siscoe east property was limited until the 1960’s with the exception of small-scale production at the Stabell property between 1935 and 1937 when 1,750 ounces of gold were produced at an average grade 0.27 oz/ton of gold. In addition to these mining activities a 312 metre shaft with drifting and cross cutting established at 5 different levels. Between the early 1960’s and late 1990’s several small exploration programmes were completed that included IP, VLF and HEM geophysical surveys as well as near surface drilling.
Between 2002, when Alexandria acquired the property, and 2006 a total of 2,750 metres of drilling was completed over 5 holes. In addition Alexandria has completed property-wide magnetic, IP and seismic surveys have been completed.
CURRENT EXPLORATION Top
In the Summer of 2008 Alexandria entered into a joint-venture agreement with Niogold that would allow Niogold to earn a to 50% interest in the property by issuing 650,000 shares (issued) and completing $750,000 of exploration work on the property.
Since that time Niogold has completed a small exploration programme consisting of 3 holes that tested the western flank of the Bourlamaque Bathlotih and tested the extension of the K-Shear zone around the Sullivan Mine. Niogold successfully intersected gold mineralization grading 43.67 g/t Au over 1.3 m in hole SE-09-004 northwest of the Sullivan Mine in the same quartz-tourmaline vein stock work that characterizes the Sullivan Mine.
