Meat Cove Zn Deposit, Inverness County
UTM (NAD27)
Zone 20
 Northing 5208730 / 5208360 / 5208160
 Easting 682840 / 683150 / 683150
Details:

 The Mine Road leads south from the Meat Cove-Lowland Cove Road, approximately 3.2 km west of the village of Meat Cove (200 m west of the juncture of the road with French Brook). The Northwest Zone is exposed along a brook valley, a short distance west of the Mine Road, approximately 600 m south of the juncture of the Mine Road with the Meat Cove-Lowland Cove Road. Coordinates 2: Adit Zone The adit is located along the Mine Road, approximately 500 m southeast of the Northwest Zone. It was driven on a steep east dipping slope, along the south side of a tributary of French Brook. The discovery outcrop is located along this tributary, approximately 70 m northeast of the adit portal. Coordinates 3: South Trench Zone Two large trenches are found on top of the hill, approximately 200-300 m south of the Adit Portal.

Further Info:

 The Meat Cove Deposit is primarily a Zn deposit in which sphalerite is the dominant sulphide mineral. The sphalerite occurs as coarse grained massive crystalline aggregates, as disseminations, as bands and as veins. Chatterjee (1979) reported that sphalerite commonly replaces brucite, antigorite and pyrite. He also noted that the most significant Zn-mineralization occurs as a replacement of forsterite bearing units within the magnesian alteration zone. Other minerals reported to occur within the deposit include pyrite, pyrrhotite, chalcopyrite, galena, graphite, fluorite, arsenopyrite, stannite, germanite and renierite. Pyrite, which is the second most common sulphide mineral, occurs as independent crystals and aggregate masses.

Other Minerals:
 sphalerite, arsenopyrite, marcasite, stannite, braunite, pyrite, pyrrhotite, germanite, renierite, galena, chalcopyrite, graphite

Reeves Tin Pit, Lunenburg County
UTM (NAD27)
Zone 20
 Northing 4953870
 Easting 379700
Details:

 The Reeves Tin Pit is located 5.1 km west on the Dalhousie Road (Forties Road) from the village of New Ross, Lunenburg County. The prospect is found within the community of Forties and 0.5 km south of road on the Reeves farm. Reeves is a common name in the New Ross area. The prospect may be reached by going 80 metres south along a woods road that starts at a small man-made pond behind the barn on the Reeve's farm. At that point turn west from the woods road onto a foot path and walk southwest for 120 m to a cleared area. The prospect is located in this cleared area and in 1982 consisted of a water-filled pit, outcrops and overburden dumps (O'Reilly et al., 1982). Since 1982 the pit has been filled in by the land owner but dump material can be found laying about.

Further Info:

 Mineralization: Flecks of fluorite and blue-turquoise fluorapatite are common in the pegmatite and associated leucogranite that accompanies the pegmatite. The mineral assemblage that is reported to occur in the central zone of the pegmatite is impressive and includes: cassiterite, amblygonite, lepidolite, fluorite, topaz, tourmaline, beryl, wolframite, scheelite, columbite, durangite, metatorbenite, tapiolite and monazite. A Department of Mines and Energy field check reported in 1982 indicates that most of these minerals are not obvious and only fluorite, lepidolite and fluorapatite were noted (O'Reilly, et al., 1982).

Faribault (1908) reported that a pit was dug in 1903, uncovering cassiterite- and fluorite-bearing quartz boulders. Consequently, digging continued and a shaft was sunk into bedrock with work continuing for the next few years. A pit was sunk (7.5 m deep, 3.6 m long and 3 m wide) on a pegmatitic segregation within light grey leucogranite. The site has been visited by numerous persons since Faribault's time but the dyke was apparently not visible due to the water level in the pit and the fact that much of the outcrop had since been covered over by dump material.

Other Minerals:
  amblygonite, microlite, monazite, morinite, scheelite, tapiolite, topaz, tourmaline, triphylite, tungstite, wolframite, apatite, fluorapatite, beryl, cassiterite, columbite, durangite, lepidolite, metatorbernite
