Pacaud - Gold
Numerous small deposits or showings of gold, copper, lead and silver are known to occur along the periphery of the intrusive.
“The Laskowski gold-silver occurrence consists of a mineralized portion of a 10 to 12km long zone of brecciated and quartz veined tonalite in the Round Lake Batholith.”
“Hydrothermal alteration abruptly begins at the edge of the 100 metre wide breccia zone. The predominant mineralogical change is albitization and sericitization (likely phengitic mica) of plagioclase. Plagioclase albite content increases near quartz veins. The mafic minerals, mainly biotite and epidote, are replaced by sericite. Carbonate has also been introduced. Alteration within the breccia zone is pervasive and uniform.”
“Changes in whole rock chemistry are also uniform: Na, Ca and Sr are displaced while K is enriched. A saline hydrothermal solution diffusing from conduits probably produced the alteration effects.”
“Ore mineralogy consists essentially of euhedral pyrite and amoebal chalcopyrite which are erratically distributed in the quartz veins. Minute grains of silver telluride and native gold commonly occur together, within or outside the sulphides. Carbonate can be found along any grain boundaries in the veins. The textures suggest the following paragenesis:
Quartz/pyrite → gold/silver telluride → chalcopyrite → carbonate.”
In 1978, Little Long Lac Exploration optioned the property from Mr. Laskowski and re-sampled the gold showing, did limited geophysical surveys and diamond drilling (4 holes, 343 metres). Surface assays of up to 0.77 oz/ton Au were obtained and shallow diamond drilling followed the gold values to a depth of 87 metres (270 feet). Although no logs are available, two of the four drill holes are reported to have intersected gold values. Interestingly, two drill holes are also reported to have intersected kimberlite dykes but were no analysed for diamonds.
In 1979, Don Hurd optioned the claims and performed further stripping.
Between 1977 and 1984, Mr. Laskowski performed various programs of bulldozing and shallow diamond drilling for assessment purposes.
Kerr Addison Mines Ltd. compiled information on the property in 1980 and there are indications that they performed an IP survey over the claims.
In 1985, R.W. Mining and Milling Limited optioned the property but no record exists of any work they undertook.
In March 28, 1985, Mr. John Kirwan wrote a report on the property for Earth Resource Associates summarizing knowledge of the property to that point. In the report, Mr. Kirwan refers to assay taken by Gilrow Resources Limited of Timmins which ranged in value from trace to 1.5 oz/ton Au and trace to 6.38 oz/ton Ag. The average of 15 trench samples taken by Gilrow was said to be0.295 oz/ton Au.
Also in 1985, Yorbeau Resources Inc. sampled the trenches and with 3 samples delimited a zone of 4.5 metres (14.75 feet) wide in a dynamited face which averaged 0.25 oz/ton Au (8.63 g/ton Au).
In 1986, Queenston Gold Mines Limited sampled the Laskowski showing and reported values up to 0.775 oz/ton Au and 3.38 oz/ton Ag.
Exsics Exploration Ltd. performed VLF EM and magnetometer surveys on the property in 1986 for Jogrem Resources Ltd.
No further historical, geological or economic data is available as regards this property.
