Camp scale land package in the prolific Red Lake – Uchi Greenstone Belt, with the potential to host multiple multi-million-ounce deposits with high-grade gold starting near surface.


  • Camp scale land package in geology prospective for gold.

  • Multiple multi-million-ounce gold deposit potential.

  • High-grade gold intersected near surface in historical drilling.

The 9,100-hectare (“ha”) Sky Lake Project is a 25 km long camp scale property in the prolific Red Lake – Uchi Sub-Province of northwestern Ontario, which has seen production and discoveries of over 40 million ounces (“M oz”) of gold including Evolution Gold’s Red Lake Mine (~25 M oz) and newly acquired Bateman project (640,000 oz) and the recent LP Fault discovery (pre-resource) on Great Bear Resources’ Dixie property.

NewOrigin Gold is initially targeting a historic gold deposit called the Koval Zone, which has not seen any drilling since the 1990s. Historical results from the Koval Zone include: 6.26 grams/tonne gold (“g/t Au”) over 22.7 metres (“m”), including 8.78 g/t Au over 16.0 m within 100 m of surface.

The Company’s aim is to prove out a gold district at Sky Lake, by exploring for multiple multi-million-ounce gold deposits in three styles of mineralization:

  • Bousquet-style mineralization as seen at the Koval Zone – Gold-bearing pyritic “quartz sericite-schist”.

  • LaRonde-style mineralization identified by isolated electromagnetic and coincident induced polarization anomalies.
    (The Bousquet-LaRonde Camp in Quebec has produced over 25 million ounces of gold over 40 years)

  • Musselwhite and Pickle Lake-style mineralization – Gold-bearing iron formation identified by magnetics that has seen limited drilling.


Key Attributes And Exploration Potential

NewOrigin Gold’s Sky Lake property hosts the “Koval” gold deposit, which was discovered by surface prospecting in the 1950’s. An initial resource was outlined, and gold mineralization was traced by shallow drilling over a length of 1,500 m. A subsequent collapse in the gold market caused the property to sit dormant for 30 years until confirmatory exploration was conducted by LAC Minerals Ltd. following that company’s major discovery at Hemlo. Work was suspended for a second time due to a collapse in the gold market in the late 1980’s.  LAC was subsequently taken over by Barrick Gold Corp. and evaluation of the deposit again sat dormant for 30 years.

Recently, Tri Origin Exploration (predecessor to NewOrigin Gold) was been able to option the Koval claims and has acquired by staking a 100% interest in a 27-kilometre (“km”) long claim package surrounding Koval to give it a dominant land position in a very prospective mining camp.


Sky Lake is located within the Red Lake-Uchi Subprovince, of northwestern Ontario which hosts over 40 M oz of past production and currently delineated gold resources. Rocks at Sky Lake share important attributes with those at the world-class Red Lake Gold Mining District to the west and with new discoveries made in the region. In closer detail, the property is bounded by the Pickle Lake Gold Mining Camp to the northeast, the Dona Lake Gold Mine to the east and the Golden Patricia Gold Mine to the west. These mines have collectively produced over 4 M oz of gold. More recently, Australian-listed Ardiden Inc., have defined the 110,000 oz Kasagaminnis gold deposit is located on a contiguous property to Sky Lake. The deposit’s iron formation host is interpreted to extend onto Sky Lake. Ardiden is currently drilling along strike and below the current resource with the intent to define a +1 million ounce deposit on their property.

The prominent location of Sky Lake within a very productive mining region, promising results from historic work, a partially delineated resource and new targets outlined by the Company’s recent work all combine into a tier one gold exploration project. NewOrigin Gold’s past and current management also recognize strong geological similarities between the gold occurrences at Sky Lake and those of the important Bousquet/LaRonde gold producing district in Quebec where over 25 M oz of gold have been produced. These similarities indicate that new, as yet to be discovered, multi-million-ounce gold deposits may occur at Sky Lake and justify continued, detailed exploration.

Property Description

The property is located 310 km northwest of Thunder Bay and approximately 30 km southwest of the Town of Pickle Lake, Ontario. The eastern part of the property is adjacent to power lines and a paved highway and the Koval deposit is within 20 km of this infrastructure, a 30 km flight from Pickle Lake, and accessible by seasonal winter road, barge, and float plane.

The Sky Lake property is one of the largest landholdings in the Pickle Lake District and covers prospective rock units for a strike length of 27 km. It consists of 100% interest in 446 single cell mining claims, covering an area of approximately 8,760 ha. The Company is completing its earn-in to a 96% interest in 29 patented mining claims covering an area of approximately 305 ha from Barrick Gold Corporation by spending CA$500,000 over a 5-year period.


The Sky Lake property is within the Archean Meen-Dempster or “Pickle Lake” greenstone belt. This is one of a number of arcuate, deformed and segmented greenstone belts stretching across northwestern Ontario. These greenstone belts host important operating gold mines, past producing gold and base metal mines and new deposits under development. In particular, Sky Lake shares the same geological environment as the important gold mining centers of Red Lake and Pickle Lake.

At Koval, rock units trend easterly and dip steeply south to vertical. The majority of the property is underlain by a mixed volcano-sedimentary sequence which can be divided into three parts; a northern mafic volcanic assemblage, a central mixed intermediate to felsic volcanic and sedimentary assemblage and, a southern sedimentary assemblage. The Northern Assemblage consists predominately of mafic volcanic flows and near its southern margin contains intercalated iron formation and altered rock. Partially explored gold occurrences are documented in these altered and iron-rich rocks. The Central Assemblage is a complex sequence of intermediate to felsic volcanic flows, breccias and tuffaceous rocks separated by sedimentary units and occasional mafic flows. The Koval deposit is associated with altered, pyritic and sericitic felsic schists within the Central Assemblage. There is a distinct boundary or “break” between the Central Assemblage and the extensive Southern Assemblage. The Southern Assemblage although poorly mapped, appears to consist of a thick sequence of greywacke, shale and graphitic sedimentary rock.

Koval Gold Deposit

The gold zones on the Koval Claims were discovered in outcrop and partially delineated by drilling during the 1950’s by Pickle Crow Gold Mines Ltd. and subsequently Hasaga Gold Mining Ltd. both of which had operating gold mines in the Pickle Lake District at the time. Additional drilling was conducted by Little Long Lac Gold Mines Limited during the 1970’s and LAC Minerals Ltd during the 1980’s. In total 133 drill holes have been completed in the vicinity of the Koval deposit.

Selected gold assay results from historic drilling include near-surface drill core intervals of 6.26 “g/t Au” over 22.7m, including 8.78 g/t Au over 16.0 m, 7.26 g/t Au over 19.4 m, 6.50 g/t Au over 16.8 m, 4.96 g/t Au over 13.0 m and 3.97 g/t Au over 14.2 m. These assay results were obtained from the mineral assessment files of the Ministry of Energy, Northern Development and Mines (“ENDM”) and have not yet been confirmed by NewOrigin Gold drilling. In addition, reports sourced from ENDM files quote a small resource of gold however these resource estimates are not NI43-101 compliant and are not represented to be accurate by NewOrigin Gold without confirmatory work being completed.

Reconstruction and interpretation of historic drill results by NewOrigin Gold indicate that the resource area is part of a larger series of subparallel, steeply-dipping gold-rich rocks within an area extending approximately 1,500 m long in an east-west direction up to 100 m wide. Three sub-parallel mineralized zones, spaced between 25 to 50 m apart, have been interpreted within this area. These zones have been traced for a distance of 1,500 m along strike and to depths between 50 and 100 m. within the same area gold mineralization has been intersected at 200 m below surface. The zones remain open and it is management’s interpretation that the zones may merge at depth or along strike to the east to form a single more continuous, steeply-dipping gold-rich mineralized zone.


The gold-bearing rocks observed on surface at the Koval zone are siliceous and sericitic, pyritic schists. These rocks are stratabound and are most abundant along the southern and northern margins of an altered intermediate tuffaceous rock in contact with sedimentary units.

Work History

The majority of drilling at Sky Lake was conducted on the Koval claims by Hasaga Gold Mines Ltd and Pickle Crow Gold Mines Ltd between 1953 and 1954 (88 holes, 6,397 m). A second phase of work coincided with an increase of gold price during the 1980’s. This work was focused both on and adjacent to the Koval claims and included preliminary geophysical surveying as well as drilling. Drilling during this period was conducted by, Long Lac Mineral Exploration Ltd, 1975 (13 holes, 1,537 m), LAC Minerals Ltd, 1987 (24 holes, 5,225 m) Moss Resources Ltd, Golden Terrace Ltd and through limited programs conducted by other explorers throughout the region. This resulted in identification of previously unrecognized gold occurrences across the current Sky Lake property. Many of these occurrences were intersected by short, exploratory holes and no follow-up work has been conducted since the 1980’s. These regional occurrences represent important exploration targets for NewOrigin Gold.

Recent Work

NewOrigin Gold’s field work has included modern, high resolution heliborne electromagnetic and magnetic surveying, collection and analysis of over 1,000 humus and 500 mineral soil samples, geological mapping, rock geochemical and alteration studies, detailed grid work including Induced polarization geophysical surveying and a preliminary seven-hole diamond drill program.

The Company has also compiled a substantial geotechnical database of historic exploration work and drilling. Historic drilling data on the patent claims has been compiled from Ontario government files and internal reports authored by LAC Minerals Ltd. that were recovered by NewOrigin Gold. A database of 133 drill holes totalling 13,954 m of drilling has been audited and correctly located. Of these, 114 holes were in the vicinity of the mineralized zones, 105 of which had extensive, recoverable assay records. No assay data is available for the remaining nine (9) holes although it is assumed that, based on core log information, they penetrated one or more of the zones.

Modelling of these zones was completed in a 3D environment by NewOrigin Gold. Three zones comprising the Koval deposit were modelled and several other subsidiary zones were recognized. In general, each zone has a strike of 065° and dip of 83° south. In places, the zones appear to exhibit pinch-and-swell structures both horizontally and down dip but this may be a function of drill hole density and drilling pattern. Where a drill hole with low or no assays intersected the model, the logs (if available) were examined in detail to identify alteration and/or sulphide mineralization that supported the modelled zone.

All of this information has provided plans, sections and a preliminary mineralization model to target future drill programs planned by NewOrigin Gold.

In 2019, the Company completed a “deep-looking” induced polarization (“IP”) survey consisting of 13 line-km in 8 separate lines covering 2 kms of strike length along the Koval gold zones. The survey was conducted by Dias Geophysical Ltd. with a modern, proprietary survey technology which returned readings taken from surface to an estimated depth of up to 400 m below surface.


Other Targets

Three ore deposit environments have been identified at Sky Lake; stratabound, pyritic gold deposits of the Bousquet/Hemlo type, gold-rich massive sulphide deposits of the LaRonde type and, iron formation-hosted gold deposits of the Pickle Lake or Musselwhite type.

The Koval gold deposit is hosted by altered, pyritic, felsic volcanic rock and represents a gold occurrence of the Bousquet type. Importantly, this environment has not been recognized by previous explorers and leaves an extensive area along trend from Koval open to exploration.

The airborne electromagnetic survey completed by the Company has delineated many, as yet undrilled, anomalies both along trend from Koval and associated with felsic volcanic rocks. These are promising targets which may represent massive sulphide occurrences of the gold-rich, LaRonde massive sulphide deposit type.

At the Pickle Crow, Central Patricia, Dona Lake and Golden Patricia mines past-production exceeding 4 M oz came from altered sulphidic rocks and from quartz veins within sheared mafic volcanic rocks in close proximity to iron formation. This environment most closely resembles the altered rock/iron formation units at the southern margin of the Northern Mafic Assemblage, which have been successfully tested by Ardiden Inc. at Kasagaminnis Lake. The assemblage extends across the entire the Sky Lake property. At Sky Lake, these rocks contain historic, only partially explored gold occurrences and represent a high-priority exploration target for the Company.

In addition, ultramafic rocks are host to the past producing Thierry Mine, located 30 km north of the Sky Lake property which produced approximately 113 million pounds of copper and 2 million pounds of nickel. Deposits of this type have not been explored for at Sky lake.
