Kennady North Project
The Kennady North Project is located 280 kilometers east-northeast of Yellowknife, NT in the District of Mackenzie. The Kennady North project consists of 16 mineral leases and 58 mineral claims totaling 61,000 hectares.
Kennady North covers a portion of the southeastern Slave Geological Province, an Archean terrain ranging in age from 4.03 Ga to 2.55. The area consists of granodiorite intrusions, high grade gneisses and migmatites, with volcanic and sedimentary supracrustal rocks typical of many greenstones belts in the Slave Province.
The Kennady North Project has been the focus of numerous exploration programs since 1992, culminating with the discovery of the Kelvin and Faraday kimberlites. Exploration activity was suspended in 2003 and resumed in 2011. Exploration work has been performed by a number of operators. Initial exploration was conducted under the direction of Mountain Province Diamonds as the 100 percent owner. Subsequent to the formation of a joint venture with De Beers in 1997, De Beers Canada conducted exploration activity. In 2005, Mountain Province resumed 100 percent control over the Kennady North Project and supervised exploration through to May 2012, when Kennady Diamonds Inc. was established.

FAT deposit one of Canada's largest undeveloped gold projects. Gold resources of 8.0 million ounces in the measured and indicated categories plus an additional 3.4 million ounces in the inferred category (see Reserves/Resources Table).
A total of 589 holes have been drilled on the FAT deposit by Seabridge, Placer Dome and Noranda totaling 169,000 meters.
An updated Preliminary Economic Assessment ("PEA") was released in June 2011. The study predicts annual production of 383,000 ounces of gold for 16 years at our estimated cash cost of US$599 per ounce (see news release of June 2, 2011).
A $16 million exploration, engineering and environmental program was successfully completed in 2011 to raise the PEA to a Preliminary Feasibility Study (PFS). (See news release of March 30, 2011 for details).
An updated NI 43-101 compliant mineral resource model (effective Jan. 9, 2012) significantly increased measured and indicated gold resources and expanded the size of the deposit (see news release of January 10, 2012).
A PFS completed in July, 2012 estimated proven and probable reserves of 6.5 million ounces of gold, an average annual production of 385,000 ounces at an average cost of $780 per ounce and a mine life of 15 years (see news release of July 24, 2012).
An $8.5 million exploration program in 2012 focused on finding a second major deposit along the Greenstone Belt (see news release of March 14, 2012). This program discovered the Walsh Lake deposit (see news releaseof November 28, 2012).
An initial resource for the Walsh Lake deposit was announced in early 2014 totaling 4.62 million tonnes grading 3.24 g/T and containing 482,000 ounces of gold, all inferred (see news release of March 11, 2014).

Aurora performed Mag, and HLEM surveys as well as mapping and prospecting on the property.
The Enigma Property is located about 33 kilometres south of Yerington in Lyon County, Nevada. It consists of 17 Federal Lode claims on BLM land. It is located in the Walker Lane Belt and is predominantly underlain by Mesozoic granite cut by a NNW trending shear zone. Gold occurs in veins and breccias within this shear zone over a distance of approximately 1,500 m. Exposure is poor and the system is best defined in electrical resistivity data. Grab samples from shaft dumps, pits and a road cut have returned up to 73 g/t Au with 10 of 41 samples collected to date returning greater than 2.0 g/t Au. The host mineralization is coarse crystalline, occasionally laminated quartz-hematite-limonite veining with disseminated pyrite, galena, and tetrahedrite. Work to date has mapped the shear zone from intermittent outcrop data and geophysical surveys. A structurally controlled 3D IP survey is planned to locate prospective shoots along the host shear zone by means of their chargeability response.

Widespread surface gold mineralization
Past production (hard rock and placer)
Geophysics defines large targets below and along strike of known showings
The Strongbox Property is located in Tule Canyon, 55 km southwest of the town of Goldfield in Esmeralda County, Nevada. The property consists of 22 Federal Lode Claims centred on Tule Canyon and covering mineralization on the east and west sides of the canyon. Video presentation available here.
The Strongbox Property is located in the Walker Lane in an area underlain by granodiorite of the Sylvania Pluton and cut by Miocene to recent NW striking strike-slip faults and N to NE trending extensional faults. The area is distal from known Tertiary volcanic centres and has not been extensively explored in modern times.
Placer mining in Tule Canyon dates from 1848 when Mexican placer miners first began work in the area and has continued until recent times. Numerous bedrock occurrences in the walls of the canyon along the length of the creek were mined on a small scale although no hard rock production is documented in the immediate property area. On the west side of Tule Canyon (West Zone), a miner named “Honest Tom” Jaggers reportedly mined his “Dark Secret Mine” from the 1890’s until perhaps the 1930’s. A recent, undocumented and more extensive underground mining operation ran on the east side of Tule Canyon (East Zone) following a strong vein which was mined over a length of about 130 m to a depth of about 100 feet. A dry wash placer operation of perhaps the same vintage mined altered bedrock near the site of the Dark Secret Mine.

Committee Bay Project
In June 2017, Aurora Geosciences on behalf of Silver Range conducted a three-dimensional induced polarization (3DIP) survey over a grid centred on the silica caps at Skylight. The survey defined a network of chargeability linears, collectively forming a network with a nexus centred beneath the region of the silica caps. Elevated gold, silver and arsenic values are associated with several of these linear chargeability anomalies. The southern terminus of the most prominent appears to be the target inconclusively tested in Rimfire hole RC07-04. This failed to reach target depth but nonetheless intersected 10.67 m @ 0.490 g/t Au. Surface rock samples collected in this area returned 0.53 g/t Au and 0.86 g/t Au. The chargeability linear follows a gully with an associated clay alteration zone containing dickite and hydrothermal kaolinite.
Results of exploration work to date at Skylight indicate that it is underlain by a nearly completely preserved epithermal system and that the system is gold-bearing. The recent geophysical surveys have defined the system’s structural architecture and identified an area where fluid may have been most intense. Silver Range is designing a drill program to conclusively test this system, targeting the linear chargeability anomalies with best geochemical suppo

The Gold Chief Property is on the east flank of Chief Mountain, 9 km north of Caliente in Lincoln County. The property consists of 8 Federal lode claims and covers the most significant producing mine in the Chief Mining District.
The Gold Chief Mine operated from the early 1900’s until 1940 with documented run-of-mine production of 5224 t @ 6.18 g/t Au (1913-1914) and 189 T @ 1.1 OPT Au-equivalent (high grading / 1937-1940). Underground development included a 131 metre inclined shaft, 300 metres of drifts and cross-cuts, and near surface stopes. Recent sampling of the back of the remaining glory hole by Silver Range in 2016 returned 14 m @ 1.93 g/t Au including 4 m @ 3.86 g/t Au with best results (1 m chip) of 4.58 g/t Au.
The Gold Chief Mine and nearby SOA Mine are hosted in Cambrian Highland Peak carbonates. Mineralization consists of wide fault breccia in the Stampede Detachment Fault and an associated lateral ramp. It has been intersected in the SOA Mine and in drill holes over a length of approximately 300 m along the Stampede fault. Precious metal mineralization appears to have originated from either the nearby Caliente Caldera or from the Cobalt Canyon diorite stock which underlies much of the Chief Mining District. There is potential for significant mineralization in the area if the favourable carbonate stratigraphy and structural network persists to the east and north.
Aurora managed the geological mapping and prospecting on Silver Range's Strongbox Project for the 2017 season.

Lac des Gras West
Aurora Geosciences has worked with North Arrow for a number of years on many projects collecting, processing, and interpreting geophysical data on a their exploration projects.
The Lac de Gras Project is located in the Lac de Gras kimberlite field, close to two of the world’s richest diamond mines: Diavik and Ekati. North Arrow considers the area to have significant exploration potential for the discovery of new diamondiferous kimberlites. Exploration of the project is conducted under joint venture agreement with Dominion Diamond Corporation under which Dominion owns ~61% interest in the project. Dominion is the most important diamond company in the NWT, owning an interest in both the Diavik (40%) and Ekati (80%) mines.
Previous work in the project area has included airborne surveys, till sampling, ground geophysics and limited diamond drilling. Untested geophysical anomalies and unexplained geochemical anomalies remain, but the glacial history of the project area south of Lac de Gras is considered to be complex, having been exposed to multiple glacial events.
In 2013, Dominion earned their interest in the Project by conducting an extensive, $5 million program of reverse circulation overburden drilling intended to fully evaluate basal tills for kimberlite indicator minerals. The program utilized a helicopter portable reverse circulation drill capable of sampling a complete till column to reach basal till not accessed by previous surficial till sampling. A total of 757 overburden reverse circulation drill holes (1,704 samples) tested the basal tills of the property for kimberlite indicator minerals (KIMs). The 2013 exploration program was managed by Aurora Geosciences Ltd. of Yellowknife, NT and till samples were processed at Overburden Drilling Management Limited of Ottawa, ON.
A $1,280,000 exploration budget for 2016 included data compilation work, airborne geophysical surveys and ground follow up work. Most recently, this past September a 3,020-line kilometer helicopter-borne magnetic/electromagnetic survey was completed. Exploration plans for 2017 have not yet been determined. Once a program has been decided upon by the joint venture and a budget announced North Arrow will decide on whether to participate or have its interest in the project diluted.
In order to focus spending on the drilling of two other properties North Arrow elected not to contribute its 45% share of costs to the 2016 program and Dominion elected to fund the full program and budget. As a result the Company expects its interest in the LDG joint venture has been diluted to approximately 39% (exact project expenditures not yet known).
