Exploration History

1961: New Jersey Zinc Exploration (Canada) Ltd. dug several trenches on a gold-bearing qtz vein. 1963: N.J. Zinc drilled 5 diamond-drill holes, totalling 162.49 m, on the gold-bearing qtz vein as part of a 6 hole, 212.78 m program. 1984: St. Joe Canada Inc. commissioned an airborne mag survey over a large part of the Muskegsagagen Lake area. 1984: St. Joe staked claims to cover the N.J. Zinc showings. Performed ground mag and EM surveys and geological mapping and prospecting. 1985: St. Joe did a diamond-drill program which relocated the gold-bearing qtz vein. Six diamond-drill holes intersected the Golden Patricia Vein. 1986: St. Joe did a definition diamond-drill program which outlined a potentially mineable deposit. 1986: St. Joe commenced an underground exploration program on the deposit with the driving of 2 declines and the extraction of a bulk sample. Further airborne mag and EM surveys were commissioned to cover a much expanded claim group. Additional ground geophysical surveys were completed and several additional targets were tested by diamond-drill holes. 1987 (March): St. Joe Canada announced vein going into production. 1988: St. Joe taken over by Bond Gold Canada Ltd. Mine production started Sept. 1988. 1989: Lac MInerals acq. major interest in Bond Gold Cda. and took over operation of mine. 1990: Lac Minerals did a deep drill program on the deposit.

Geology Comments

Dec 07, 2005 (B Nelson) - The Golden Patrica mine produces gold from a quartz vein in a shear zone which cuts through a mafic metavolcanic succession. The vein averages 40 cm thick and is remarkably continuous over a strike length of more than 3.3 km. The vein and shear zone strike roughly E and dip steeply N, more or less concordant with the regional stratigraphy. In addition to containing the Golden Patricia vein, the shear zone encompasses the remnants of feldspar porphyry intrusions on the footwall and hanging wall of the vein. These porphyries were mylonitized by the deformation. Originally, they were identified as felsic tuffs. The hanging wall is characterized by chlorite and biotite alteration which grades into the mafic metavolcanics. The footwall is characterized by silcification and sericitization and by a thin band of sulphidization (pyrrhotite) adjacent to the vein. The Golden Patricia vein is mineralized with fine-to-coarse visible gold which is commonly associated with pyrrhotite. Pyrite, chalcopyrite, sphalerite and galena are also observable in the vein. Generally, sulphides comprise less than 5% of the vein material. The quartz vein also contains tourmaline, carbonate, sericite, chlorite and rutile. The vein is not uniformly mineralized. Ore shoots defined by grade tend to rake about 70 degrees E. The Golden Patricia vein exhibits D2 foldiing along its length and is fractured and locally offset minor distances along the late D3 plane which strikes almost perpendicular to the vein.

Lithology Comments

Dec 07, 2005 (B Nelson) - Stott and Corfu (1991) suggest that the shear zone may be a splay of the Bear Head fault zone which is a boundary fault to the greenstone belt. The mafic metavolcanic succession which hosts the Golden Patrica vein and shear zone is comprised of tholeiitic flows with interflow beds of tuff, immature clastic sediments and iron formation. It is intruded by gabbroic intrusions, feldspar porphyry dykes and by late biotite-rich mafic dykes commonly identified as lamprophyres. The mafic metavolcanic succession is overturned.

Mineralization Comments

Dec 07, 2005 (B Nelson) - The Golden Patricia Vein is accessed by 2 declines 1 km apart and a 1.5-compartment shaft. The vein is mined using conventional shrinkage stoping techniques. The ore is ground and milled using conventional technology and the gold is recovered using a combination gravity and Merrill Crowe cyanide leach process. Recovery averages 96%.
