Green Bay Project

Project Summary

The Green Bay Property encompasses four gold deposits two of which, the Hammerdown and Rumbullion have seen historical mining development.

The most important and well-defined gold deposits include the Orion, Muddy Shag, Hammerdown and Rumbullion and all occur in the Hammerdown Deformation Zone (HDZ). The HDZ is described has a 100-250 wide structural corridor of strong ductile to brittle shearing hosted in the uppermost units of the Catchers Pond Group. All these deposits are cut-off at depth by a major structure called the Captain Nemo Fault and subsidiary faults.

Limited exploration work has been completed to find the off-set of the Hammerdown deposits, however recent deep seeking geophysical surveys by Maritime have identified chargeability targets that may host high grade gold veins similar to he Hammerdown mineralization. The chargeability targets, located proximal to the Hammerdown and Orion deposits, have seen historical shallow diamond drilling which reported narrow auriferous quartz/sulphide veins similar to Hammerdown style veining.

The Lochinvar VMS style zinc/silver rich deposit also occurs in the HDZ along with the Golden Anchor gold veins and Beetle Pond VMS alteration zone.

Regional Exploration Targets

Orion (Au)

The Orion deposit is located approximately 2.0 km southwest of the Hammerdown deposit. The Horsehead Fault is a northerly striking fault that dips 50° to the east and terminates the Orion Gold zones to the west. As the fault trends oblique to the N50E strike of the Orion Vein system, the base of the gold zones plunge about 40° to the northeast. Recent drilling has encountered high-grade gold in the veins close to the fault, indicating a possible structural relationship of high-grade gold with the plunge of the Horsehead fault. In 2022 diamond drilling at Orion intersected several high grade intervals over significant widths highlighted by drill hole BB-21-133 with 4.8 gpt Au / 13.6m, including 7.0 gpt Au / 8.1m and BB-20-116 with 26.2 gpt Au / 4.0m, including 96.4 gpt Au / 1.1m. The Orion gold veins are completely open in this plunge direction and to the east. Intruding the stratigraphy are numerous sill-like lenses of quartz-feldspar porphyry up to 20 metres thick and a myriad of mafic dykes and sills up to 10 metres thick. 

Golden Anchor (Au)

The Golden Anchor prospect is located approximately 100 m northeast of the Hammerdown gold deposit and occurs stratigraphically above the zinc rich Lochinvar VMS deposit. In the Golden Anchor area, the geological structures change direction to the south creating a fold nose and the potential for dilational openings to occur creating a similar mineralizing structural environment similar to the Hammerdown and Rumbullion deposits. Drilling in 2020 and 2021 tested the Golden Anchor and Lochinvar trends, intersecting multiple narrow quartz sulphide veins extending the Golden Anchor trend to the east and west. Drill hole GA-20-35 tested the western extension of the Golden Anchor trend towards the Hammerdown deposit intersecting thin veins with visible gold and returning 10.24 g/t Au and 18.0 g/t Ag over a 4.0 metre interval. The Golden Anchor veins have been partially delineated over a strike length of 600 m and remain open in all directions.

Lochinvar Deposit (Zn, Pb, Cu, Ag, Au)

The Lochinvar VMS deposit is located approximately 200 m northeast from the former Hammerdown Gold Mine. Two steeply plunging, massive sulphide lenses have been traced from surface to approximately 200 m depth where they remain open, though there are indications that they will be truncated at depth along the late Captain Nemo Fault. The mineralization is partially delineated over a strike length of 700 m and remains open to the northeast.

The mineralization consists of heavily disseminated to massive sphalerite, galena, chalcopyrite, and pyrite with lesser barite and significant tennantite and electrum. It occurs within a steeply-dipping, strongly sericitized, carbonatized and locally chloritized, soda-depleted (0.2% Na2O), schistose felsic volcanic package up to 75 m thick. The altered felsic package is separated from an underlying undeformed mafic volcaniclastic unit by the “Captain Nemo Fault” and is overlain by a unit of aphyric, green andesite/dacite fragmental rocks.

Drilling in 2020 intersected a thick zone of mineralization with 0.85 gpt Au, 150.9 gpt Ag, 0.73% Cu, 3.33% Pb and 7.62% Zn over 11.6 m, including 0.74 gpt Au, 210.7 gpt Ag, 2.03% Cu, 10.64% Pb and 23.83% Zn over 2.5 m in drill hole GA-20-25.

Rendell-Jackman Cu-Au Deposit

The Rendell-Jackman is a massive sulphide prospect was discovered in 1909. Subsequent IP surveys identified a chargeability anomaly extending approximately 1,200 m to the northwest and southeast of the underground mine workings. Recent selective mineralized rock sampling over the Rendell-Jackman workings graded to a maximum of 9.9% Cu and 12 g/t Au, averaging 2.9% Cu and 3.0 g/t Au. A sample chipped from this outcrop graded 11.2% Cu, 0.195% Zn, and 0.44 g/t Au. Recent IP surveys on the Rendell-Jackson clearly defined the subsurface mineralization and indicate a stronger broader response at depth.

Timber Pond VMS (Cu, Zn, Au)

The Timber Pond Massive Sulphide showing is located 8 km east of Hammerdown and approximately 200 m south of the south end of Timber Pond. The showing is hosted by chloritized, magnetite-rich ophiolitic basalt and is composed of a massive sulphide horizon that is 4 m thick and 8 m long. The massive sulphide contains mostly pyrite and pyrrhotite, with laminae of chalcopyrite and sphalerite. Noranda Exploration Company Ltd. completed a five-hole drill program between 1987 and 1989. The best result obtained from this program were 1.0% Cu, 0.23% Zn, and 2.8 g/t Au over 4.0 m (Jacobs, 1999).

In 2021 Maritime Resources identified a large regional EM anomaly coincident with the Timber Pond VMS Showing. Geophysicists modelled the EM anomaly and successfully generated an EM plate which was subsequently drilled in holes TP-21-01 and TP-21-02 which encountered a pyrrhotite rich massive sulphide lense with 2.06 m of 0.5% Cu and 3.48 m of 0.77% Cu respectively.

Beetle Pond (Au/Zn)

The Beetle Pond showing, is located 1 km east of the Hammerdown deposit and is interpreted as being an extension of the Golden Anchor and Lochinvar Prospects that have been offset by folding and faulting. The showing is 500 m East of Golden Anchor zone and is associated with a high-grade gold and base metal in soil trend that extends for over 325 m and is associated with a large coincident magnetic and IP anomaly. Historic drilling in the Beetle Pond area identified local base metal mineralization and extensive hydrothermal alteration. Beetle Pond was drilled in 2022 with the first hole encountering a quartz/sulphide vein with abundant visible gold. Drill hole GA-22-46 intersected a high grade vein assaying 150.37 g/t Au over 0.20 m in a new discovery. In the footwall to the mineralized quartz veins a lower sulphide horizon containing local occurrences of base metals was identified and is interpreted to be an extension of the Lochinvar Horizon.

Batters Brook (Zn, Pb, Cu, Ag, Au)

The zone occurs within a 1.5 km long mineralized felsic volcanic horizon which joins the Rigel massive sulphide prospect along strike to the northeast. The discovery hole, BB-07, yielded the best historical intersection cutting 6.3 m averaging 6.57% Zn, 2.7% Pb, 0.75% Cu, 50.8 g/t Ag, and 1.48 g/t Au, including 0.9 m of 23.4% Zn, 12.6% Pb, 2.2% Cu, 147 g/t Ag, and 1.0 g/t Au. Anglo American completed four drillholes to test this zone’s potential to extend down plunge towards the northeast and southwest, as well as down dip to 300 m depth. Of these, only one hole, BB-77, intersected massive sulphides comparable to the high-grade shallowly drilled intersections previously obtained. This hole intersected a 20 cm wide section of zinc-rich massive sulphides approximately 280 m below surface, suggesting the zone may plunge steeply towards the southwest where it remains open below this depth.

Ursa Major/Ursa Minor/Southern Cross (Au, Ag, Zn)

These prospects are located approximately 4 km southwest of the Batters Brook massive sulphide prospect. Of these, Ursa Major and Southern Cross, occur within mafic volcanic rocks while the Ursa Minor prospect occurs within felsic volcanics of the Batters Brook package. Host rocks to these prospects are interpreted to lie stratigraphically below the Batters Brook-Rigel horizon. The Ursa Minor zone consists of stringer and semi-massive sulphide mineralization returning low-grade base and precious metal assays over broad widths including 0.23 g/t Au and 25 g/t Ag over 30.8 m as well as 1.1% Zn over 13.5 m.
