Point Location Description: Trenching
Location Method: Conversion from MDI
Access Description: The property is located in Ryan and Palmer twp. Travel to Batchawana Bay along Highway 17N and turn onto a gravel road named the Carp River Rd. for approxiametly 15km.
The ground was held under by Mr. Ole Bjorna of Batchawana Village who staked the ground because of the high magnetic attractions. Mr. Bjorna optioned the claims he had staked to Algoma Ore Properties in 1952. In 1952, Algoma Ore Properties Ltd., drilled 4 holes on the east part of the iron formation. The west part was held at that time by Jalore Mining Company that carried out a survey and in 1954 drilled 3 holes at the west end of the iron formation. In 1960, the iron formation was then optioned to Cleveland-Cliffs where geological surveys, surface sampling and a 1962 drill program completed by the company drilling 9 holes. The company explored the property for a posible lump ore with a target of 1 million tons. They indicated that in 2 of the lenses there might be a possible total of 300,000 tons at 65.5% Fe. The balance of the iron formation intersections were stored by Cliffs at Ishpeming Michigan. In 1966, Phelps-Dodge completed a drill prgoram on an adjacent copper prospect. One hole was drilled that cut the iron formations. In 1971, Algoma Ore Division of Algoma Steel Copr Ltd. had Cliffs sample the core which was stored at Ishpeming. Algoma brought the samples to Sault Ste. marie where they were assayed in the company's laboraory. In 1971-72 Algoma chip-sampled new exposures carrying out assaying, Davis Tube reducibility and grindability tests. The property was optioned to M&S Construction. The company had made efforts to test a 150 ton bulk sample to determine if they have a deifinite customer for 25, 000 tons a year. The company has stripped the overburden from the immediate area where Cliffs obtained the intersection of high grade material. They have opened a trench across the same lense to the east.

Mar 28, 2011 (A Pace) - E-W trending, magnetite-quartz iron formation dipping 45 to 65S. In Ryan Twp. there are two parallel zones 200 to 300 feet wide, 100 to 300 feet apart. In palmer Twp. the formation is 9300 feet long and up to 200 feet wide. The iron formation outcrops in the northwestern portion of the Batchawana Greenstone Belt. the belt is bordered to the north, south and east by ganitic terrain, and to the west the belt is unconformably overlain by Keewanawan volcanic and sedimentary rocks. The iron formation is oxide facies characterized as a banded magnetite-chert iron formation. Low coontent of hematite present but fibrous iron silicates have been identified. The iron formation contains a small presence of sulphides primarily as pyrite dissimenated along the bands.

Mar 28, 2011 (A Pace) - There were 3 holes drilled by Jalore Mining Company Ltd., in 1954 they include: Hole 1: 86 feet of 45.95% Soluble Fe and 40.65% of magnetic Fe Hole 2: 19 feet of 47.19% soluble Fe and 41.36% magnetic Fe Hole 3: 15 feet of 54.29% soluble Fe and 44.30% of magnetite Fe. Total Footage of 120 feet of 45.95% soluble Fe and 40.65% of magnetic Fe. Chip samples conducted by Algoma Ore Division through Cleveland-Clifss are illustrated below: Pancake #1- 69.7% soluble Fe and 68.83% magnetic Fe Pancake #2 - 66.0% soluble Fe and 65.15% magnetic Fe Sample 21560 - 49.9% Fe and 43.20% magnetic Fe Sample 21561 - 69.4% soluble Fe and 43.20% magnetic Fe Sample 21562 - 42.9% soluble Fe and 38.73% magnetic Fe Sample 21563 - 39.1% soluble Fe and 37.17% magnetic Fe
Date: Aug 11, 1999
Geologist: G Bennett
Notes: The iron formation normally contains 15 to 30 percent soluble Fe but local sections up to 17 feet thick are composed essentially of magnetite. In Palmer Twp. true widths of 30 to 118 feet were intersected, with averages for total Fe of 26.2% over 103 feet, 30.1% over 118 feet, and 29.8% over 80 feet. In Ryan Twp. one lens, 600 feet long, has a possible 600 000 tons per vertical 100 feet, of which 200 000 tons may be of direct shipping grade. Tests on 12 samples which ranged from 30.7 to 67.5% Fe gave a magnetic conentration at 1325M between 58.9 to 71.0% Fe and 0.6 to 18.3% SiO2 for a 60.6 to 97,9 oercent recovery.
