Green Bay Project

Exploration - Green Bay Property

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.

Numerous sporadic exploration campaigns have been completed over the Property since the 1950's with base metals being the focus in the earlier years and it was not until the 1980's that gold became an exploration target. The Lush's Bight Group which underlies the northeastern portion of the property is well known for ophiolitic style VMS deposits, however, in more recent years, exploration has identified potential shear hosted mesothermal style gold mineralization. The Catchers Pond Group which underlies the bulk of the Property, is host to the known gold deposits, as well as, VMS style base metal prospects and showings along with accompanying stringer style feeder zones contained within large hydrothermal alterations zones. These rocks are considered to be analogous to those hosting the Buchans orebodies.  Previous explorers have discovered numerous volcanogenic massive sulphide showings throughout the project with grades and mineralogy similar to the Buchans ore.

Regional  Exploration Targets

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. Previous exploration in the area has highlighted anomalous gold in soil surveys while historical shallow drilling reported multiple intersections of auriferous quartz/sulphide veins both along strike and in the hanging to the Lochinvar base metal deposit.

In 2019, Maritime completed a deep seeking geophysical Volterra IP survey (9 km) over the Golden Anchor area. The survey located a large, untested chargeability anomaly starting at a depth of approximately 200 m below surface. Historically, chargeability responses are associated with sulphides, as at Hammerdown and Orion where gold is associated with pyrite. The 2019 two-hole drill program completed in late November to December 2019 targeted the 350 m long by 150 m wide chargeability IP anomaly. The 2019 drillholes (GA19-23 and GA19-24) were drilled north and south designed to scissor the chargeability anomaly at a target depth below 200 m. The drilling intersected multiple narrow quartz sulphide veins in a hanging wall mafic sequence down to approximately 200 m to an intensely hydrothermally altered and pyritic felsic volcanic sequence believed to be the Lochinvar horizon which hosts the zinc/silver rich Lochinvar VMS historical deposit 600 m to the west. Assaying of the hanging wall quartz sulphide veins reported anomalous to significant gold grades up to 11.7 g/t over 0.3 m with anomalous base metal values geochemically similar to the Hammerdown / Rumbullion veins further west. The highly altered pyritic felsic units returned anomalous gold values with significant silver and associated highly anomalous zinc values. One 0.35 m intersection of semi-massive sulphides in GA19-24 returned an assay of 169 g/t Ag and 12.8% Zn. Both holes intersected intense and chaotic fault zones with classic tectonic breccias reflecting the folded and faulted geological structures in the area.

In 2020 and 2021 an additional 20 drillholes tested the Golden Anchor and Lochinvar trends. Drilling intersected multiple narrow quartz sulphide veins extending the Golden Anchor trend to the east and west. The best result identified in the 2020 program was GA-20-35 which tested the western extension of the Golden Anchor trend towards the Hammerdown deposit.  The hole intersected thin veins with a spectacular occurrence of visible gold and returning 10.24 g/t Au and 18 g/t Ag over 4 m. As a result of this additional drilling the gold vein system at Golden Anchor has been remodelled and is presently interpreted as a fan of nine stacked veins.  The Golden Anchor veins that have been partially delineated over a strike length of 600 m.

Lochinvar Deposit (Zn, Pb, Cu, Ag, Au)
The historical 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.

Rendell-Jackman Cu-Au Deposit
The Rendell-Jackman is a massive sulphide prospect was discovered in 1909. Initial drilling identified two lenses of massive sulphide and in 1910 a shaft was sunk on the Northern lens to a depth of 46 m. In total an estimated 1600 tonnes of ore were brought to surface before closing in 1912 after the death of the Mine Manager. Subsequent IP surveys identified a chargeability anomaly extending approximately 1,200 m to the northwest and southeast of the workings. All historic drilling tested relatively shallow targets, the deepest drillhole extending to 137 m. In 1990, three drillholes tested reconnaissance targets northwest of the workings with only one drillhole testing the IP chargeability extension (Figure 7 10). 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 (Fraser, 2015).

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 grading 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 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 as part of the Company’s 2022 drilling program with the first hole encountering a quartz/sulphide vein with abundant visible gold. Samples of the mineralized interval were sent for rush analysis at Eastern Analytical and returned grades of 150.37 g/t Au over 0.20 m in drill hole GA-22-46. 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 zone remains open at depth and in both strike directions, however, drilling completed by Hudson Bay HBED in 2001 and 2002, has further restrained the potential for possible significant extensions to the mineralization. The discovery hole, BB 7, yielded the best intersection to date 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 by Major General. 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. The Ursa Major and Southern Cross prospects have returned sections of disseminated to semi massive sulphides assaying up to 3.7% Cu over 0.2 m.
