The Portage properties, which comprise 38 contiguous units staked in the name of Northeast Exploration Services Ltd., are located approximately 75 km. west of Bathurst, NB (Fig. 1). The spatial distribution of the claims, which transect the Portage – Popple Depot road as well as adjacent properties, are included on Figure 2, together with the two main mineralized zones. The Restigouche Mine is situated approximately 1 km northeast of the property boundary (Fig. 2).
The property has been previously explored by Selco, Placer Development, Northeast Exploration Services Ltd., Golden Chalice Resources Inc., and Slam Exploration Ltd.
Located in the western portion of the Bathurst Mining Camp, the Portage properties are underlain by Ordovician mafic to felsic volcanic rocks and tuffs, as well as metasedimentary rocks. Siluro-Devonian mafic, felsic, and sedimentary rocks outcrop on the western portions of the properties (Fig. 3).
The principal mineralized zone, the Portage deposit, is a tabular stratabound zone up to 60 m thick, dips approximately 45 degrees to the west, and is sited near the contact between the Ordovician Boucher Brook metasedimentary/mafic volcanic rocks and the Ordovician Mount Brittain felsic volcanic rocks (Fig. 3).
Diamond-drill hole CP-57 intersected 47 m of stringer sulfides averaging 2.30% Zn, 0.36% Pb, and 0.21% Cu, including a 3.4 m section averaging 5.81% Zn, 2.97% Pb, and 0.61% Cu (Fig. 4). Figure 5 comprises another section on the Portage zone.
A new mineralized zone was located by Slam Exploration Ltd. in 2018. Diamond-drill hole PZ-18-01 intersected a core length of 2.42 m averaging 8.74% Zn, 7.49% Pb, and 0.13% Cu at a depth of 147.5 m, immediately below the Siluro-Devonian/Ordovician contact (Figs. 4 and 6). The principal mineralized zone was also intersected in the same hole (deeper intersection) at 267.47 m and continued intermittently over 10 m, averaging 0.84% Zn and 0.27% Pb (Fig. 6). Both mineralized zones are open along strike and at depth.
“Likewise, a swarm of untested conductors and magnetic anomalies extends 2 km northeast from the new massive sulfide discovery toward the Restigouche deposit, all suggesting potential for discovery of additional Brunswick-type massive sulfide deposits on the Portage property.” (Slam Exploration Ltd. Report of Work 478495, September 2018).
