Lime Hill Zinc Deposit

Lime Hill is located in Cape Breton Nova Scotia, 25 km northeast of the deep water port of Port Hawkesbury. Access is over 800 meters of ATV road from the MArble Mountain road.

The East zone has been traced by trenching and drilling over a strike length of 300 m. It contains three subzones which were described by Patterson (1993) as follows: "Within the Main Zone, sphalerite occurs as tabular bodies ranging from 1 to 30 cm thick, striking 010° and dipping steeply to the west. The mineralization, averaging 4.5 m in thickness, pinches and swells down dip and along strike from 2- 7.5 m and has been estimated to contain 227,000 tonnes at 8.9% Zn (Patterson, 1984). The "C" zone mineralization occurs in a synclinal structure plunging at 30° to the north and also displays wide variation in thickness and grade. The zone averages 2.5 m thick, is 200 m long and has been drilled to a depth of 75 m. Patterson (1984) estimates 112,000 tonnes at 5.46% Zn. The #2 zone is narrow, averaging 1.7 m, and is estimated to contain 36,000 tonnes at 3.49% Zn." Patterson (1993) described the West zone as follows: "The West zone comprises a series of bands and disseminations of sphalerite in westerly-dipping, tabular bodies of dolomitic limestone. The zone strikes N-S for 200 m, averages 1.8 m in thickness, has been traced down dip for 50 m, and is estimated (Patterson, 1984) to contain 50,000 tonnes at 6.25% Zn." The sphalerite mineralization is stratabound, and occurs in both disseminated and massive forms. Medium- to coarse-grained sphalerite is present in bands that vary from 1 cm to several metres in thickness. Pyrrhotite, which forms the second most common sulphide mineral, occurs as submassive to massive bands, disseminations and stringer veinlets. Small amounts of pyrite, and trace amounts of chalcopyrite also occur as disseminations within the Zn-mineralized marble units. Kidlark (1975) reported that the sphalerite is generally segregated from the pyrrhotite, but that the pyrrhotite does occasionally occur as disseminations within the sphalerite bands and vice versa. Scheelite and wollastonite were identified by Chatterjee (1977) in some of the drill core where it was described as occurring as disseminations and bands in the Ca-rich marble units. The wollastonite potential of the deposit was investigated by Bluestack Resources Limited between 1985 and 1988. Tungsten values up to 2.8% were obtained from grab samples. There are over 4600 metres of diamond drilling in 82 holes recorded on the deposit, all are on my claims. Values of up to 38.8% Zn over 1.2 metres and 10.17% Zn over 7.6 metres were encountered. Mineralization exists in carbonates with massive, laminated and fracture fill styles occurring. The deposit has been opened at surface by trenching and appears to be amenable to surface mining. Much depth and along strike potential exists on the property and in the wider area. The sphalerite occurs in two zones that parallel the lithological layering and foliation within the marble host rocks.

Mineralization is stratabound in the pre-Cambrian Georges River dolomitic and calcitic marble sequence.

Guernsey (1927): Mr. J. D. Guernsey mapped the North Mountain area for the Geological Survey of Canada in 1926. He reported an occurrence of pyrite and sphalerite located in a small pit on the farm of Mr. D. Campbell, halfway between Lime Hill and Ross Brook.
Keating (1955): Belcher Mining Corporation Limited conducted a regional stream water geochemical survey over their Closure 9 block. A sphalerite bearing limestone outcrop was located along McCuish Brook during the follow-up surveys conducted over a heavy metal geochemical anomaly defined along this brook. A soil geochemical survey conducted over the sphalerite occurrence outlined a large Zn anomaly.

Knutson and Wilson (1956): Belcher Mining Corporation Limited conducted magnetometer and EM surveys over the soil anomaly detected in their 1955 surveys. The surveys did not produce any anomlies that coincided with areas of known zinc mineralization.

Rogan (1960): Conwest Exploration Company Limited conducted geological mapping, soil geochemical, electromagnetic and magnetometer surveys over the Lime Hill Prospect during the 1959 field season. They followed-up on the results of these surveys by drilling seven diamond-drillholes for a total length of 2,375 feet.

Spencer (1960): The Consolidated Mining and Smelting Company of Canada Limited conducted geological mapping, soil geochemical, magnetometer and electromagnetic surveys over the Lime Hill Prospect. They followed-up on these initial surveys by digging 1200 feet of trenches over the mineralized outcrops and soil geochemical anomalies.

Morrison (1964): The Southern Maryland Agricultural Association conducted magnetometer, electromagnetic (EM) and soil geochemical surveys over the Lime Hill Prospect.

Boyd (1969): The Patino Mining Corporation drilled 8 holes for a total of 3 683 feet during the 1968 field season.

Innes (1974; 1975): Brascan Resources Limited conducted line-cuting, geological mapping, soil geochemical and overburden drilling surveys over the Lime Hill showing. They followed-up on the results of this survey work by digging 18 bulldozer trenches over a combined length of 3 424 feet. They also relogged the drillcore obtained in a drilling program conducted by Silvermaque Mining Limited in 1974. Innes reported that Silvermaque drilled 35 holes with an aggregate length of 5 192 feet, but no record of this work, other than Brascan's drilllogs for the relogged drillcore, is available in the Nova Scotia Department of Natural Resources assessment files.

Kidlark (1975): Brascan Resources Limited dug 20 more bulldozer trenches with an aggregate length of 4 952 feet to follow-up on their earlier worked described in Innes' s 1974 and 1975 reports. They also drilled 18 diamond-drillholes for a total of 3 748 feet. This report also includes a structural study conducted by D. Hattie which suggests that the zinc is in part bedded, and is probably pre-metamorphic in origin.

Patterson (1984): Bluestack Resources Limited completed a detailed compilation report on the Lime Hill Zinc Deposit.

Pegg (1986): Bluestack Resources Limited completed a prospecting survey over the Lime Hill deposit in search of wollastonite. They also dug 18 backhoe trenches and relogged the available drill core to evaluate it for its wollastonite content. The trenching defined three zones of possible economic importance. The best intersection of wollastonite reported in the relogged drillcore is a 9.1 foot section in hole S-34 which was estimated to contain 50%.

Hill (1987): J. R. Hill sampled and studied the Lime Hill Zinc Deposit as part of his Geological Survey of Canada, regional studies of the matacarbonate formations of Cape Breton Island.

Pegg (1988): Bluestack Resources Limited completed dug some trenches over the Lime Hill deposit to test for wollastonite. They extracted small bulk samples from the trenches for processing tests. They also completed a small mapping program over a cut grid.

Justino (1994): Mario Justino conducted geological mapping and prospecting surveys over the Lime Hill area. A new zinc showing (see record F14-052) was located during this survey work along a woods trail east of MacPhee Brook.

Barrett (1996): This report documents the previous work history, but it provides essentially no new geological information on the deposit.

Barrett (2003)(2006): These reports provide the same information. A new geological model prepared by the report author are provided, but not much new additional exploration work.

The known mineralization is entirely within 3 licences consisting of 12 claims totaling 194 hectares. The deposit is located at the brow of a hill approximately 1 km back from the Bras D'or Lakes, an inland sea.
