Falcon Nickel Project
The Falcon Nickel Project (“Falcon”) is comprised of 67 claims owned 100% by ALX totaling 20,002 hectares (49,427 acres) that are prospective for nickel, copper and cobalt (“Ni-Cu-Co”) mineralization, located in the northern Athabasca region of Saskatchewan. Falcon hosts a magmatic nickel-sulphide mineralizing system that has been underexplored by modern methods until its acquisition by ALX.
The centre of Falcon is located approximately 18 kilometres (11.2 miles) northwest of Stony Rapids, Saskatchewan within the Tantato Domain, otherwise known as the East Athabasca Mylonite Triangle, which forms a segment of the Snowbird Tectonic Zone. A long history of exploration beginning in 1929 discovered numerous Ni-Cu-Co showings within Falcon’s boundaries, including the Axis Lake deposit (“Axis Lake”), the Rea Lake deposit (“Rea Lake”) and the Currie Lake deposit (“Currie Lake”). However, no exploration was carried out from 2007 to 2019 until ALX acquired its claims by staking and subsequent purchase in 2019.
A site visit carried out by ALX in October 2019 at the Currie Lake deposit area confirmed grades in surface rock samples of up to 3.17% nickel and 0.40% copper from historical trenches, along with anomalous grades of cobalt, gold and platinum group metals. ALX has since identified drill targets at Currie Lake located deeper than the reported historical mineralized intersections. ALX’s geophysical modeling completed in February 2020 has revealed that the historical drilling at Currie Lake, last carried out in 1957 and 1965, overshot the highly-prospective anomalies defined by the recent geophysical modeling. Other prospective targets along the northern Currie Lake trend have been developed for ALX’s inaugural 2020 drilling program, which began on March 2, 2020.

On March 25, 2020, ALX announced that new zones of nickel and copper mineralization have been intersected in the third hole of the 2020 drilling program at its 100%-owned Falcon Nickel Project.
ALX reports that drill hole FN20-003 on the V-3 conductive target (“V-3”) completed to a depth of 327 metres intersected sulphide mineralization in two zones, the first from 234.69 to 235.92 metres and the second between 246.22 and 247.38 metres. The presence of nickel and copper mineralization in hole FN20-003 has been confirmed by the use of a portable Niton™ Model XL3t GOLDD+ X-ray fluorescence (“XRF”) device on the drill core. Preliminary logging describes the mineralized interval as containing disseminated to semi-massive, net-textured sulphides, with visible pyrrhotite, chalcopyrite and pentlandite hosted within noritic rocks. Core samples are shipped to SRC Geoanalytical Laboratories in Saskatoon, SK for base metals analyses with results expected later in March 2020.
V-3 was chosen as a drill target following ALX’s review of a 2005 airborne survey that identified a deep airborne electromagnetic (“EM”) conductor near the survey detection limit of the era. ALX’s subsequent surface geochemical work over the V-3 conductor in 2019 to 2020 found nickel-copper anomalies in both soil and lake sediment samples, and a follow-up ground EM survey was completed in March 2020 to better define the target. A borehole EM survey was carried out on hole FN20-003 after its completion, which, through Maxwell computer modeling, indicates a large, “off-hole” conductive zone lying above the mineralized intersections. ALX’s third drill hole is believed to have “clipped” mineralized stringers represented by the smaller, “in-hole” anomaly that could be related to the larger conductive zone - modeling results indicate a potential size for the “off-hole” anomaly of 365 metres long by greater than 50 metres of depth extent.
Impact of the COVID-19 Virus on the 2020 Exploration Program
ALX has suspended further exploration work at Falcon until further notice. The Government of Saskatchewan declared a province-wide, public health emergency on March 18, 2020. In the final week of the drilling program, although no COVID-19 virus infections were reported in the northern community of Stony Rapids, SK, the Company undertook precautionary measures following the escalation of infections reported in Canada and around the world. ALX’s on-site workers in the 2020 drilling program were supplied with disinfectant sprays, sterile towels and disposable gloves in order to carry out their duties for the remainder of the program. In addition, ALX has temporarily closed its Vancouver head office with employees instructed to work from home until otherwise notified.
On March 16, 2020, ALX announced that nickel and copper mineralization was intersected in the second hole of the 2020 drilling program at Falcon.
Falcon drill site for FN20-001 and FN20-002
Drill hole FN20-002 targeted the V-1 conductive anomaly
(“V-1”) proximal to the historical Currie Lake deposit area (“Currie Lake”).
The drill hole was completed to a depth of 108 metres and intersected sulphide
mineralization beginning at a depth of 47.03 metres and continuing to 67.89
metres. The presence of nickel and copper mineralization in hole FN20-002 has
been confirmed by the use of a portable XRF device on the drill core.
Preliminary logging describes the mineralized interval as containing
disseminated to semi-massive, net-textured sulphides, with visible pyrrhotite
and chalcopyrite hosted within noritic rocks. Core samples were shipped to SRC
Geoanalytical Laboratories in Saskatoon, SK for base metals analyses with
results expected later in March 2020.
ALX’s first hole, FN20-001, was drilled to a depth of 165
metres but did not encounter significant sulphide mineralization. A borehole EM
survey was immediately carried out upon completion of the hole, which detected
a conductive zone at a shallower depth. Hole FN20-002 targeted this anomaly
from the first drill set-up. A comprehensive ground EM survey is recommended
over V-1 to better define conductive zones in the V‑1 area when working
ALX geologist surveying drill hole location
Following the completion of the second hole, ALX moved the drill to the V-3 target area (“V-3”), located approximately 4 kilometres east of V-1, to test a geophysical target defined by a completed ground EM survey (see ALX news release dated March 2, 2020). ALX plans to update its shareholders on its drilling progress as more information becomes available during the winter 2020 program.
In January 2020, ALX completed a helicopter-supported Spatiotemporal Geochemical Hydrocarbon (“SGH”) survey from the surface ice of Konkol Lake, which is located over the eastern end of the Currie Lake East airborne conductor trace. ALX collected 45 lake sediment samples from a grid consisting of nine lines spaced 150 to 200 metres apart. Results from the SGH survey are expected in late February 2020 and will be integrated into the targeting matrix for ALX’s 2020 drilling program.
Lake Sediment Sampling on Konkol Lake, January 2020
On January 16, 2020, ALX announced the results of a reconnaissance soil sampling program and a new geophysical interpretation study carried out on Falcon. The integration of the new exploration data with the known geology mapped at the Project has led to the definition of a compelling new target area for drilling in the winter of 2020.
The Currie Lake East (“CLE”) airborne conductor was modelled by Condor Consulting, Inc. of Lakewood, Colorado (“Condor”) as part of a detailed interpretation of historical digital data from three airborne surveys flown over the Falcon area between 1991 and 2008. Condor is recognized internationally as expert in the field of airborne electromagnetics. The CLE conductor was first detected by a 2005 Versatile Time Domain Electromagnetic (VTEM) airborne survey, but the results were not processed with modern computer modelling techniques until ALX commissioned its 2019 study. Condor describes the CLE conductor as a deeper, late-time, high-priority EM conductor approximately 1.2 kilometres in length that is associated with a magnetic anomaly. This conductor is located approximately 4 kilometres north of the historic Axis Lake East nickel-copper-cobalt deposit and ranks as one of the most significant geophysical anomalies described in the Condor interpretation report to ALX.
In October 2019, ALX collected a total of 45 soil samples from a land-based grid aligned over the surface trace of the CLE conductor which were submitted to Activation Laboratories Ltd. (Actlabs) in Ancaster, Ontario for conventional and Spatiotemporal Geochemical Hydrocarbons (“SGH”) analysis. This initial soil survey program represents ALX’s first test of the SGH process, which is reported to detect buried mineralization at depths up to 500 metres. A nickel-copper anomaly was detected within the grid over the western end of the CLE conductor trace. According to the SGH report, the results could indicate the presence of a “Redox zone”, which may be associated with the presence of nickel-copper mineralization beneath this anomaly. The nickel and copper anomalies at Falcon directly coincide with one another, giving further confidence that this result might represent a surface indication of nickel-copper type mineralization.
On November 20, 2019, ALX announced additional analytical results from rock samples collected during a reconnaissance prospecting program in October 2019. Samples taken from historical trenches and from outcrops in the northern part of the Project returned values of up to 3.17% nickel and 0.402% copper, along with anomalous values of cobalt, gold, platinum and palladium.
In October 2019, ALX carried out a site visit with two objectives: (1) to sample historical trenches at the Currie Lake nickel-copper-cobalt deposit, known for its higher grades of nickel, and (2) ground truthing of certain geophysical anomalies identified in a 2005 airborne survey that were never followed up. Sixteen rock samples containing up to 50% to 60% sulphides were collected from three historical trenches, seven outcrop samples were collected near the surface traces of high-priority geophysical conductors, and 45 soil samples were collected over the surface trace of a conductor. The trench samples returned the higher nickel values and the results of the samples that returned over 1.0% nickel are shown in the table below:
Table 1. Additional Analytical Results of Falcon Nickel Project Surface Rock Samples
Falcon hosts three shallow magmatic nickel sulphide deposits, one of which, Axis Lake, can be seen from the air due to its distinctive gossanous (oxidized) appearance. ALX believes that the higher grades of nickel found at the northernmost Currie Lake deposit may represent the near-surface expression of a higher-grade section of the mineralizing system at Falcon. Through its geophysical review and modelling of historical airborne survey data, which is still underway, the Company is seeking to locate magmatic conduits and feeder systems that could represent the sources of the known deposits at the Project, and provide additional mineralized zones.
On November 12, 2019 ALX announced initial analytical results from a reconnaissance prospecting program at Falcon. Three of the rock samples were submitted on a rush basis to SRC Geoanalytical Laboratories in Saskatoon, SK, and returned the following values shown in Table 2 below:
Table 2. November 12 Analytical Results of Falcon Nickel Project Surface Rock Samples
ALX has produced a preliminary 3D geologic model for Falcon, which is being expanded to better understand the controls on the known zones of nickel-copper-cobalt mineralization hosted by the Project.
ALX received an exploration permit for geophysical surveying and diamond drilling at Falcon and is currently developing drill targets for an exploration program for the winter of 2020.
- On June 12, 2019, ALX announced its first acquisition of claims at Falcon totaling approximately 7,414 hectares (18,322 acres). The Company staked 25 claims during a staking rush in late May 2019 in the historic Axis Lake area, and added to its land position by purchasing a single claim from an arms-length vendor at the Rea Lake deposit located southeast of Axis Lake.
- On October 7, 2019, ALX announced the acquisition of additional claims prospective for Ni-Cu-Co mineralization at Falcon through a purchase agreement with Eagle Plains Resources Ltd. (“Eagle Plains”) for a 100% interest in 31 claims totaling approximately 5,064 hectares (12,513 acres) located in the historic Axis Lake area.
- On October 24, 2019, ALX announced it had increased its land position at Falcon through a purchase agreement with an arm’s length vendor for a 100% interest in 9 additional claims totaling approximately 7,508 hectares (18,553 acres) located in the northern Axis Lake area, bringing ALX’s land position at Falcon to its current size of 20,002 hectares.
Falcon is located approximately 20 kilometres southwest of ALX’s Flying Vee Nickel Project, and near recent staking by Kobold Metals, a private U.S. company exploring for energy metals. Of the three known deposits present on the property, Axis Lake is the most significant Ni-Cu-Co deposit within the Falcon area.
Axis Lake Deposit
Ni-Cu-Co mineralization at Axis Lake appears semi-continuous over at least a 5 kilometre strike length parallel to the regional east-striking structural trend. Mineralization is comprised of a south-dipping, sulphide-rich layer varying 1½ to 10 metres thick and is hosted by strongly deformed, granulite facies mafic rocks (Geology of the Axis Lake East Zone Nickel-Copper Deposit, Tantato Domain, Northern Saskatchewan, Normand, 2015). Primary magmatic sulphide mineralization consists of pyrrhotite, pyrite, chalcopyrite and pentlandite ranging from finely disseminated to coarsely disseminated or semi-massive network to massive (Vivian and Lo, 2007). Preliminary analysis of published geochemical data of mineralized samples from the eastern part of the deposit shows remarkable similarities between this deposit and the world-class Voisey’s Bay nickel deposit in Labrador (Normand, 2015).
Rea Lake Deposit
Rea Lake is located approximately 1.6 kilometres southeast of Axis Lake. Rea Lake occurs within granulite facies garnetiferous felsic gneisses, iron formation and banded mafic rocks close to the apex of a major southwesterly plunging synform. Mineralization is hosted by an upper metaquartzite and a lower nortite and consists of nickeliferous pyrrhotite, pyrite and chalcopyrite disseminated throughout the country rock. The mineralized zone trends east-west and dips to the south. Rea Lake is estimated to be approximately 2,700 metres long, 90 to 240 metres wide and 30 metres thick (SMDI 1627). Significant proportions of the sulphides in this deposit are remobilized and contain more pyrite and chalcopyrite as compared to Axis Lake (Technical Report on Operations, April 1 to March 31, 2006, Fond du Lac Project, Red Dragon Resources Corporation, Hull, 2006).
Currie Lake Deposit
Currie Lake is located approximately 5.4 kilometres northwest of Axis Lake. Two parallel zones of mineralization consisting of disseminations and fracture fillings of pyrrhotite, pyrite and chalcopyrite hosted by sheared norites are separated by 15 metres of metaquartzites and metagreywackes. Two mineralized zones have been identified: the Upper Zone varies from 3½ to 30 metres in width and the Lower Zone varies in width from 1½ to approximately 60 metres (SMDI 1585).
