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.
The following is a brief summary of the known prospects and showings which occur across the Property, descriptions which have been adapted from various industry and government reports.
Rendell-Jackman Cu-Au Deposit
Previous drilling at the Rendell-Jackman workings, including 15 drill holes completed before 1955, targeted the old workings in an area approximately 60 metres along strike of the mineralized shear zone. Subsequent IP surveys identified a chargeability anomaly extending approximately 1,200 metres to the northwest and southeast of the workings. All historic drilling tested relatively shallow targets, the deepest drill hole extending to 137 metres. In 1990, 3 drill holes tested reconnaissance targets northwest of the workings with only one drill hole testing the IP chargeability extension. 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. Selective sampling of mineralized float samples in the Rendell-Jackman workings by the author in 2016 found massive sulphide mineralized rocks containing high grading copper to a maximum of 11% Cu and 8 g/t Au averaging 3.6% Cu and 3.4 g/t Au. An outcrop situated immediately southeast of the workings contained pyrite and chalcopyrite stringer veins in sheared basalt. 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).
Rendell-Jackman Southeast (Au)
In 1990 a trench was dug 400 m southeast of the Rendell-Jackman deposit to test a weak gold in till anomaly. It exposed two narrow (< 5 cm) discontinuous quartz veins containing 3 to 5% sulphides. Two grab samples returned values of 7.9 g/t Au, 7.2 g/t Ag, 0.04% Cu, 0.36% Pb, 0.32% Zn and 4.3 g/t Au, 4.1 g/t Ag, 0.15% Cu, 0.30% Pb, 0.07% Zn. The quartz veins could not be traced beyond the trench (Andrews, 1991). Due to the high Pb content the mineralized quartz veins are considered similar to the Hammerdown style mineralization.
Whisky Bravo (Cu/Au)
The Whiskey Bravo Showing consists of a massive pyrite horizon hosted in strongly sheared mafic volcanic rock of the Lush's Bight group. Maximum width is 0.6 meters; continuous length is 5 meters, with a second narrower outcropping located 20 meters southeast. It is a distinct sulphide lens, with sharp planar contacts, in strongly sheared mafic volcanic rock. There are also three parallel, 5-15 cm wide, semi to massive pyrite layers/veins exposed here over a 10 meter width. Most of the sheared and un-sheared wall rock is moderately to strongly silicified/sericitized hosting 1-5% fine grained disseminated Pyrite. Gold values from the fourteen grab samples returned from 51 to 616 ppb Au. Base metal values are elevated; up to 1006 ppm Cu.
Timber Pond VMS (Cu, Zn, Au)
The Timber Pond Massive Sulphide showing is located approximately 200 meters 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 meters thick and 8 meters long. The massive sulphide contains mostly pyrite and pyrrhotite, with laminae of chalcopyrite and sphalerite. Noranda Exploration Company Ltd. completed a 5-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 meters (Jacobs, 1999).
Timber Pond (Au/Ag)
The Timber Pond Au-Ag showing was discovered during an attempt by Noranda Exploration Company Ltd. to source a 6,434 ppb Au stream sediment anomaly. The showing is contained in silicified zones within in a 1.0-2.0 meter wide shear zone with up to 15% disseminated pyrite. The shear zone is contained in a brecciated interflow sediment consisting of basaltic ash in a cherty matrix, interbedded with massive and pillowed basaltic flows (Huard, 1987). Channel sampling, by Noranda Exploration Company ltd. in 1987, returned values up to 5.05 g/t Au, 102.3 g/t Ag, 0.07% Cu, 0.38% Pb and 0.56% Zn over 1.0 meter. Subsequent diamond drilling by Noranda did not intersect the mineralized horizon (Jacobs-NFLD/2655, 1996).
Sprucy Pond Trend (Au)
The Sprucy Pond Trend (SPT) occurs over a strike length of approximately 1400 meters and contains three separate gold showings. This strong northeast striking linear is represented by sheared mafic volcanics hosting gold-bearing quartz-carbonate veins. An almost continuous exposure of bedrock was examined over a 300 meter length during a period of low water. The mafic volcanic unit here is strongly sheared, displaying a moderate to steep north-dipping, east-west trending shear foliation. Ubiquitous stockwork-style carbonate (calcite +/- ankerite) veinlets are present with local 1-2% disseminated pyrite and trace chalcopyrite mineralization. Limonite alteration and mineralization increase towards the Dambusters Showing area and further to the west. Exploration in this area has been limited to general prospecting so it is unsure at this point if the host rock is the Western Arm or Catchers Pond Group.
Foxtrot Showing: 20% disseminated pyrite and 1% galena in quartz vein (1.249 g/t Au). Strong limonite and sericite alteration. Large angular float at edge of (Sprucy?) pond.
Dambusters Showing: Outcrop quartz-carbonate vein, ~10cm wide, strongly sericitic and limonitic; 3% fine-grained disseminated pyrite, < 1% galena and trace chalcopyrite (7.72 g/t Au and 1.96 g/t Au).
Pond Edge Showing: In early 2004 prospecting located two new gold occurrences in quartz +/- carbonate veins (322ppb, 557ppb and 567ppb Au). One occurrence is hosted in a 20 - 25 meter wide zone of very strongly sericitic and limonitic sheared mafic volcanic rock which outcrops on the east side of a pond. Later grab samples taken from this exposure returned 2.278 and 1.429 g/t Au. The strike length from the Dambusters Showing to the Pond Edge Showing is ~170 meters. The Sprucy Pond Trend is interpreted to continue westward under the pond.
Bishops Pond (Au)
Gold is associated with fine-grained magnetite-rich ophiolitic basalt with 2.0% pyrite. Grab samples assayed 0.55 g/t Au; float assayed 0.43 g/t Au. A rock sampled collected in 2004 by Cornerstone Resources returned 0.985 g/t Au in this area.
Narrow (1-4 centimetres), sheeted, vertically dipping white quartz and carbonate veins with zeolites (+/- pyrite) were noted in a quarry situated near the King's Point highway. One 10 metre long 30 centimetre wide pyrite + chalcopyrite +malachite bearing quartz vein (60° strike, 70° S dip) was noted on the south wall of the quarry.
Golden Anchor (Zn/Au)
The Golden Anchor prospect is located approximately 1.5 kilometres northeast of the Hammerdown gold deposit and approximately 600 metres east of 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 dilatational 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. Two small quartz/sulphide gold zones occur in the immediate hanging wall of the Lochinvar base metal deposit. At a 5.0 g/t Au cutoff; the LI Zone has 7,065 tonnes grading 18.27 g/t Au, while the LM Zone contains 23,247 tonnes grading 7.82 g/t Au for a total historic geological resource of 30,312 tonnes at 10.26 g/t Au or 10,000 ounces contained Au. The estimate is historical and not in compliance with NI 43-101, and the category of 'geological resource' does not conform to current CIM definitions. The historical estimate is not supported by a technical report. A qualified person has not done the work necessary to verify the historical estimate as a current estimate under NI 43-101 for the Company and the estimate should not be relied upon.
Although the gold-in-soils anomaly has been tested by seven drill holes, four of the drill holes did not intersect significant gold mineralization and were reported to be drilled down-dip of the geological trend (Mullen, 1994) and could be discounted as adequately testing for subsurface gold mineralization. Two of the drill holes were drilled oblique and to the west of the gold-in-soils anomaly, one of which (RJ-93-12) intersected three gold intervals the most significant intersection grading 1.86 g/t Au over 2 metres. The final drill hole (GA-7) intersected a 0.3 metre interval grading 1.71 g/t Au and a 0.5 metre interval averaging 0.15 g/t Au. Additional drilling (6 drill holes) was completed approximately 400 metres to the north of the Golden Anchor soils anomaly, targeting a potential northeast extension of the Lochinvar deposit as defined by IP chargeability. Narrow auriferous intervals (0.3 to 0.8 metre) were intersected from all the drill holes grading from 0.01 to 0.78 g/t Au. These drill holes are situated south of a scattered weakly anomalous gold-in-soils anomaly that extends 600 metres northward in an area of coincident magnetic and moderate IP chargeability anomalies that has never been drill tested.
In 2019 Maritime completed a deep seeking geophysical Volterra IP survey (9.0 kms) over the Golden Anchor area. The survey located a large, untested chargeability anomaly starting at a depth of approximately 200 metres 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 metre long by 150 metre wide chargeability IP anomaly. The 2019 drill holes (GA19-23 and GA19-24) were drilled north and south designed to scissor the chargeability anomaly at a target depth below 200 metres. The drilling intersected multiple narrow quartz sulphide veins in a hanging wall mafic sequence down to approximately 200 meters 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 meters to the west. Assaying of the hangingwall quartz sulphide veins reported anomalous to significant gold grades up to 11.7 gpt over 0.3 metres 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 metre intersection of semi-massive sulphides in GA19-24 returned an assay of 169 gpt 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.
Beetle Pond (AU/Zn)
The Beetle Pond showing, located just south of the Golden Anchor prospect, occurs as a large base metal geochemical anomaly measuring in excess of 1.5 kilometers (700 metres within the Property). A strong IP anomaly extends approximately 700 metres across the showing and extends off the Property to the northwest. Limited shallow drilling intersected highly chloritized felsic volcanics containing widespread, visually impressive alteration and disseminated and narrow massive sulphide mineralization containing an intersection of 1.6% Zn over 2 metres. Reinterpretation of historic surveys have identified a strong EM target in the area of Beetle Pond showing and the Golden Anchor prospect. A deeper targeting drill program to ascertain depth potential of the mineralization has never been completed. The source of angular gold mineralized float discovered near Beetle Pond by Noranda grading 1.5, 3.0 and 9.9 g/t Au has never been ascertained.
Lochinvar Deposit (Zn, Pb, Cu, Ag, Au)
The historical Lochinvar VMS deposit is located approximately 800 metres northeast from the former Hammerdown Gold Mine. Two steeply-plunging, massive sulphide lenses have been traced from surface to approximately 200 metres 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 of relatively short strike length with a long axis plunging easterly. 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% Na²0), schistose felsic volcanic package up to 75 metres 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.
A historical geological resource estimate, starting at surface, of 588,000 tonnes (undiluted) with an average grade of 3.9% Zn, 1.4% Pb, 0.4% Cu, 60g/T Ag and 0.45 g/T Au was calculated by Major General Resources Ltd. (predecessor to Commander Resources Ltd.) in 1995 based on 18 drill holes. The estimate is historical and not in compliance with NI 43-101, and the category of 'geological resource' does not conform to current CIM definitions. The historical estimate is not supported by a technical report. A qualified person has not done the work necessary to verify the historical estimate as a current estimate under NI 43-101 for the Company and the estimate should not be relied upon.
Muir Pond (Zn/Pb)
Discovered by prospecting in 1911 and drilled by Brinex in the 1960's (Roderick, 1960), this prospect consists of disseminated to massive pyrite-rich sulphides associated with altered felsic volcanics. The best assay returned from this prospect came from a grab sample assaying 21.73% Zn, 9.61% Pb (Roderick, 1960), however several subsequent campaigns of drilling failed to return significant results, intersecting only narrow barren semi-massive pyrite over 0.5 m (1990, unpublished Noranda report).
Batters Brook (Zn, Pb, Cu, Ag, Au)
Major General resources completed 11 drill holes completed to a maximum depth of 150 m defining a non-compliant resource of 96,000 tonnes @ 9.1% Zn, 0.84% Cu, 6.0% Pb, 87 g/t Ag and 1.7 g/t 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 6.6% Zn, 2.7% Pb, 0.8% Cu, 51 g/t Ag and 1.5 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 4 drill holes 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 Zn-rich massive sulphides approximately 280 m below surface, suggesting the zone may plunge steeply towards the southwest where it remains open below this depth.
Rigel (Zn, Pb, Cu, Ag, Au)
Interpreted to be a continuation of the Batters Brook mineralized horizon, this massive sulphide zone has been intersected by six holes drilled to a maximum depth of 150 m by Major General Resources. Composed of semi-massive to massive sulphides, the best intersection to date includes 1.0 m assaying 11.6% Zn, 1.0% Pb, 4.0 % Cu, 23 g/t Ag and 0.8 g/t Au. Except for this intersection (hole BB-65), the zone appears to be relatively low grade typically assaying <1% Zn over similar widths.
Ursa Major/Ursa Minor/Southern Cross
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.
Pisces (Zn, Pb, Cu, Ag, Au)
The Pisces Occurrence (Cu, Pb, Zn) was discovered by Phelps Dodge in 1997, this zone is hosted by felsic volcanics of the Indian Brook package and consists of a narrow band of massive sulphides intersected in drilling grading 12.9% Zn, 8.5% Pb, 1.02% Cu, 54 g/t Ag and 0.11g/t Au over 0.13 m (drill hole GF-3, Thurlow, 1997). Subsequent drilling by Phelps Dodge intersected similar sulphides down dip; however, the zone remains untested along strike and at depth below 100 m (Thurlow, 1998).
Goldfish (Zn, Pb, Cu, Ag, Au)
The Goldfish Occurrence (Cu, Pb, Zn) was discovered by Phelps Dodge in 1997, and consists of a 0.65 m wide section of granular, pyritic massive sulphides intersected in drill hole GF-9 grading 1.36% Zn, 0.69% Pb, 0.06% Cu, 164.5 g/t Ag and 0.95 g/t Au over 0.65 m (Thurlow, 1997). The mineralization is interpreted to occur at a transitional contact between aphyric rhyolite breccias (Indian Brook felsic package) and an overlying sequence of felsic tuffaceous rocks and sediments (Batters Brook felsic volcanic package). Subsequent shallow drilling by Phelps Dodge failed to intersect additional comparable mineralization down dip or along strike; however, drilling of the horizon was hampered by a sequence of mafic dyke/sill units which dilate stratigraphy in the area.
Indian Brook (Zn)
This prospect represents one of the earliest discovered base metal showings within Catchers Pond volcanics. The showing is believed to have been originally found by Falconbridge in 1952 and consists of disseminated to stringer base metal sulphides hosted by felsic volcanics of the Indian Brook package. Grab samples from the original trenches have returned assays in excess of 10% Zn (e.g., Jenner and Szybinski, 1987).
Catchers Valley (Zn, Pb)
This prospect is located approximately 600 m east of the southeast end of Catchers Pond. The showing is reported to consist of a broad, 40 m wide, zone of disseminated sulphides with local narrow sections of semi-massive sulphides. The best assay returned from drilling included 2.5% Zn and 0.61% Pb over 0.3 m (drill hole CV-1, Major General 1996).
Harrys Brook (Cu)
In 2001 Hudson Bay Exploration drilled 2 holes in the Harry's Brook area, targeting base metal-in-soil and weak IP chargeability anomalies. Both drill holes intersected minor amounts of disseminated to fracture controlled sulphides including minor chalcopyrite within Indian Brook Formation mafic volcanics in the vicinity of Silurian-aged Harry's Lake gabbroic intrusives. The anomalies were explained as being caused by the sulphides observed in drilling. The best interval assayed graded 0.24% Cu over 0.3 metres.
