Bathurst

Positive Eu anomaly is observed for hydrothermal solution issuing from the hydrothermal vent on the seawater at East Pacific Rise (Bence, 1983 Michard et al., 1983 Michard and AlbarMe, 1986). Guichard et al. (1979) have shown that the continental hydrothermal barites have a positive Eu anomaly, indicating a relatively reduced environment. Graf (1977) has shown that massive sulfide deposits and associated rocks from the Bathurst-Newcastle district. New Brunswick have positive Eu anomalies. These data are compatible with positive Eu anomaly of altered basaltic rocks, ferruginous chert and Kuroko ores in Kuroko mine area having positive Eu anomaly and strongly support that Eu is present as divalent state in hydrothermal solution responsible for the hydrothermal alteration and Kuroko mineralization.

The Mount Fronsac North (MFN) Zn-Pb-Ag deposit is located approximately 40 km southwest of Bathurst, in the Bathurst Mining Camp (BMC), New Brunswick. The MFN deposit lies stratigraphically in the Brunswick horizon between the Nepisiguit Falls Formation and the Flat Landing Brook Formation of the Ordovician Tetagouche Group (Figs. 1-3). Footwall...

Figure 3 presents Pb in 0-5-cm soils. Elevated levels occur throughout the populated areas of the Northeast United States and the Maritime provinces, suggesting anthropogenic sources. Elevated concentrations of Pb also occur in northern New Brunswick geographically near the Bathurst mining camp and the Belledune smelter. 

Figure 5 presents Ni in 0-5-cm soils. There are no notable elevated concentrations of Ni in the region, with the exception of northern Maine and north-central New Brunswick. Figure 6 displays Ni in the C-horizon where there is a distinctive elevated Ni signature spatially correlative with the mafic rocks of northern New Brunswick that host mineralization at the Bathurst mining camp.

New Brunswick s bedrock geology is well mapped and largely well understood. Because of NB s mineral wealth, a great deal of mineral exploration work has been carried out since the 1950s. The bedrock in NB is also diverse in age. The oldest Precambrian rocks can be found in the Saint John area, whereas some of the younger ones, in the form or Triassic basalts, occupy more than half of the Island of Grand Manan. Most of NB s rocks are of Middle Paleozoic age. The triangle between Moncton, Fredericton, and Bathurst is occupied by a thick sequence of Carboniferous rocks that host... 

Till and bedrock were sampled in 2007 around the Halfmile Lake Zn-Pb-Cu volcanogenic massive sulphide (VMS) deposit, Bathurst Mining Camp, New Brunswick (Fig. 1) as part of the Geological Survey of Canada s Deep search project. Targeted Geoscience Initiative-3 (2005-2010). This project is a collaborative effort between the Geological Survey of Canada, the New Brunswick Department of Natural Resources and Queen s University.

On a regional scale (one sample per 5 km over an area of 2,000 km ) in the Bathurst region of New Brunswick, the ore elements give the best patterns relating to mineralization (Govett Pwa 1981). This is different from the mine scale where the major elements give the clearest anomalies.

The Brunswick Subduction Complex (BSC) is best know as the host sequence to world class, syngenetic volcanogenic massive sulfide deposits of the Bathurst Mining Camp (BMC) hosting deposits such as the giant Brunswick No. 12 VMS deposit (>300 Mt of massive sulfides). Less well known are the syntectonic, precious-metal breccia and (or) vein deposits/occurrences in the BSC. The shear zone-hosted Middle River gold deposit (MRG) is the most significant of these and has returned assays of up to 7.44 g/t Au over 6.5 m (DDH MR-05-06).

The Restigouche massive sulfide deposit is located in the northwestern part of the Bathurst Mining Camp (BMC), 60 km west of the city of Bathurst, northern New Brunswick. The property is currently controlled by Blue Note Mining and the company reports show that the deposit has an estimated reserve of 1.3 Mt grading 6.53% Zn, 5.05% Pb, and 99.6g/t Ag as of 2007 (Art Hamilton, Pers. Communication).
