Point Location Description: Bridge over creek between Little Mellon Lake and Mellon Lake
Location Method: Based on Assessment
Access Description: Access is via paved highway #41, approximately 11 km south of the village of Kaladar located at the intersection of highway # 7. At this point walk/drive east along a track for approximately 700 m to the test quarry site. This road is accessible by 4-wheel drive vehicles and trucks from April to November.
March 3, 1994 - Two mining claims staked in the area and assessment work carried out - mapping and test sampling of a small block for dimension stone purposes. Assessment work filed in 1995, 1996, and 1998. March 3, 1999 - Claims came open for staking. March 4, 5, 1999 - Two new mining claims staked on lots 24 to 27, con 5, and part lots 25 and 26, con4. Summer 2000 - a number of blocks were extracted for testing under a bulk sample permit.
Province: Grenville
Subprovince: Central Metasedimentary Belt
Geological Age: Mesoproterozoic
Dec 07, 2005 (C Papertzian) - Middle Proterozoic rocks of the Central Metasedimentary Belt of the Grenville Province underlie the region. Flat-lying Ordovician sediments unconformably overlie the Proterozoic rocks south of the mining claims. The Grenville supergroup consist of clastic and carbonate metasediments and mafic to felsic metavolcanics. Rocks of the supergroup form narrow northeasterly trending belts which are separated by granitoid intrusions or fault-bounded gneiss-migmatite complexes. One of the fault-bounded gneiss-migmatite complexes is the Mellon Lake Complex of tonalite-granodioritic gneisses and migmatites. This complex is 8 km. wide, trends northeast and on the southeast is fault-bounded by another belt of Grenville Supergroup strata. The age of this complex is not known. The migmatization event recorded in this complex is absent in adjacent Grenville Supergroup strata suggesting that the complex may be the basement of the Supergroup. The property is underlain by a uniform gneiss. The level of metamorphism seems to be middle to upper amphibolite. Bright suggests a tonalitic gneiss of granulite facies metamorphism overprinted with lower to middle amphibolite. The gneiss observed here is a hornblende gneiss due to prominence of hornblende over biotite. The only gneissic structure observed here was the banded gneiss. The gneiss is moderately granitized, in the range of 30%. Pegmatite veins were observed to be running parallel to the gneissosity. The pegmatite veins often contained coarse crystals of biotite approximately 3 inches square. The central ridge contained unjointed granite while the surrounding lower areas were in general highly jointed. The sheeting was in the order of a minimum of 1.5m apart.
Date: Mar 14, 2003
Geologist: C Papertzian
Notes: This deposit has been visited on a number of occaisions, the last being October 16, 2002. The test quarry was inactive at the time of the visit. Numerous quarry blocks resided on surface, ready to be shipped. The quarry had not been worked that summer. A quarry permit had been applied for and the owner/operator was awaiting the outcome of this application.
