Walton Pb, Zn, Ag, Ba Deposit
UTM (NAD27)
Zone 20
 Northing 5006204
 Easting 418116
Details:

 The past producing Walton Zn-Pb-Cu-Ag-Ba Deposit is located approximately 4 km southwest of the village of Walton, Hants County. The abandoned workings can be accessed by a secondary road leading off the main highway that leads from Walton to Windsor.

Further Info:

 The principal metallic minerals within the orebody are galena, sphalerite, pyrite, chalcopyrite, malachite, auzurite, chalcocite, marcasite, tennantite, prousite, pearceite and acanthite. Pyrite and marcasite are closely associated and occur as dull, metallic, brass-yellow, fine grained intergrowths of a colloform or concretionary texture. the galena, sphalerite, chalcopyrite and other sulphides are closely associated with the pyrite and marcasite and, in most cases, are intergrown with them. Stalactitic and botryoidal masses of pyrite and marcasite fill late fractures in the sulphide body. Galena occurs as fine grained masses, in brecciated pods, fracture- and seam-fillings and as fine disseminations. Sphalerite is light to dark brown and is almost always intergrown with galena. Chalcopyrite occurs as pure blebs, masses, stringers and irregular patches. Tennanite is lead grey and commonly intergrown with chalcopyrite, also occurring as irregular masses and small discontinuous seams. The high silver-bearing sulphosalts prousite and pearceite occur as disseminated grains and small masses within vugs and crushed breccia zones. Malachite and auzurite are rare and usually occur as coatings on other sulphide minerals.

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.
