Banroy Gold Potential

VMS deposit potential

In 2000, Geologie Quebec began producing mineral potential maps at 1:250,000 scale showing the potential for VMS deposits in Abitibi. In 2005, Geologie Quebec made “the assessment potential for VMS deposits in Abitibit”, overall favorability map was as following, the areas near the Rouyn-Noranda shows highest density of very high favorability value.

Porphyry Deposit Potential

It has been known for some time that Archean plutons containing porphyry Cu-Au mineralization exist in the Quebec part of the Abititbi Subprovince. The rocks of Archean volcano-sedimentary belts are not considered to be very prospective for porphyry deposit. However, some mineral occurrences associated deposits of this type have been identified in the Abitibi belt (Jean-Yves Labbe etc. 2007).

Orogenic Gold Deposit Potential

Archean orogenic gold deposits are generally defined as structurally controlled veins or shear margin deposits emplaced epigenetically in all lithologies occurring in volcanoplutonic belts of Archean age. These gold concentrations are the result of relatively homogeneous hydrothermal fluid flows of variable origin, including metamorphic devolatilization, felsic plutonism and mantle fluids.
Based on the assessment of the potential for orogenic gold deposits in Abitibi by Geologie Quebec in 2006, the overall favorability map was as following, the areas near the Rouyn-Noranda shows highest density of very high favorability value.

Rare Metal Deposit Potential

Recent interests for rare metals (lithium, beryllium, tantalum, cesium, niobium and rubidium) have brought more explorations in Abitibi belt. The Abitibi has seen very little exploration for rare metals for the past decades. Most works date back to 1950s. The study by Geologie Quebec in 2001 indicated that the Abitibi area has a great potential for rare metals.

In Abitibi belt, fertile Archean granites are confined to volcano-sedimentary belts and mobile sedimentary troughs, in a collisional tectonic environment. Metamorphic conditions vary from the greenschist facies to the lower amphibolites facies. The emplacement of fertile plutons predates the regional dynamo-thermal metamorphic peak and the emplacement of granitoid batholiths. Intrusions often follow fault systems, lithological contacts or any other steeply dipping regional structural element. These granites are siliceous, peraluminous, depleted in iron, magnesium and calcium.

Granitic pegmaties are exclusively related to the H plutonic suite defined by Rive (1990) in the Pontiac Subprovince and the central part of Abitibi Subprovince. This suite is composed of dominantly leucoratic syn- to late tectonic biotite-muscovite granodiorite and muscovite monzogranite plutons. Pegatites occur near batholithic contacts, at a maximum distance of 1 to 2 km from monzogranitic intrusive walls, in the country rocks. Their geochemical signature shows elevated quantities of rubidium and tantalum, and their Rb/Sr ratio is high. Monzogranites contain the flowing accessory minerals: cordirite, andalusite, sillimanite, tourmaline, Colombo-tantalite, beryl, monazite, triphylite, and molybdenite (Cerney 1991L Boily 1992).

Property Geology and Mineralization

Banroy property is located in the Abitibi greenstone belt of the superior province north-western Quebec. The belt is Archaean and consists of ultramafic, mafic and felsic volcanic rocks, clastic sedimentary rocks and tonalitic to granitic intrusions, early to post-tectonic.
The different volcano-sedimentary units are separated by long deformation zones, such as Destor-Porcupine and Larder Lake-Cadillac. Banroy property is located between these two faults and bounded by several gold discoveries and gold mining camp. (see Fig 7)

The Destor-Porcupine fault can be traced over 350 kilometres from Timmins in Ontario to the Front of Grenville at 60 kilometres ENE of Val-d’Or, Quebec. The property is associated to numerous important gold deposits such as Hollinger, McIntyre, Dome, Lightning Zone and Holloway (Ontario) and Beattie (Quebec).
The gold-bearing Destor-Porcupine and Cadillac-Larder Lake fault zones are two parallel structures that show similar features, and host ore bodies and showings with analogous structural settings and types of alteration and mineralization. Thus, the geological setting of the Banroy property, which exist between these two faults, exhibits geological features similar to the Kerr Addison (10,457,000 oz of gold from 1938 to 1996) and Holloway (4.9 M metric tonnes grading 5.9 g/t Au) ore deposits in Ontario.
The property geological background is shown in the Fig 8.

The property of Resources Cartier Inc was acquired in 2006 – 2008 by staking. 745 kilometres of airborne Mag-radiometric survey as well as prospecting, reconnaissance, lithogeochemical sampling and metals analysis were completed over the entire property. In addition, eight DDH were completed for a total of 2,541.4 metres. Based on Resources Cartier’s works,

Gold Potential

• The central part of the property is characterized by occurrence of ultramafic and mafic volcanic rocks belt deformed by Destor-Porcupine shear zone. A turbiditic basin deposit occurs in its eastern part. This geological setting is reminiscent with Holloway mine which straddles the Destor-Porcupine Fault in Ontario. The Holloway mine produced 900,000 ounces Au from 1996 to 2005.
• Seven diamond drill holes completed in 1987 by Audrey Resources inc. returned anomal gold values, notably DDH 601-87-7 with 0.34 g/t Au over 3.0 m and 0.69 g/t Au over 1.5 m in calcite veinlets within andesite.

Base Metals Potential

• Volcanic contact characterized by cherty and breccia horizon with massive pyrite and magnetite, returned 0.32% Zn over 2.7 m and 0.11% Cu over 0.70 m (DDH KI-08-025A).
• The favourable horizon is detected by several airborne geophysical anomalies that show a larger sulphide concentration 600 metres further to the east of DDH KI-08-25A.

The Banroy property is located in a similar geological environment. No work has been conducted by the property owner.
