Cluff Lake Properties (Gorilla, Bridle & Middle Lakes )

ALX's three Cluff Lake properties adjoin the former Cluff Lake Mine site, where over 62 million pounds of U3O8 were extracted during a 22-year operating life through a combination of three open pit mines and four underground mines by predecessors of AREVA Resources Canada Inc. ("AREVA") (www.areva.com).

Highlights

Gorilla Lake: Drilling in 1979 by Amok Ltd. ("Amok", a predecessor company of AREVA) encountered an intercept grading 0.85% U308 over 2.3 metres in hole CAR 425. ESO's drilling in 2006 encountered extensions to CAR 425 in 2 of the 8 holes drilled. Drill hole CLU‑01 intersected 0.46% U3O8 over 1.5 m from 174.0 to 174.5 metres. Drill hole CLU‑07 intersected two zones of uranium mineralization: one zone returned 0.17% U3O8 over 7.0 metres from 153.0 to 160.0 m, including 0.82% U3O8 over 1.0 metre and a second zone contained 0.20% U3O8 over 2.0 m from 175.0 to 177.0 metres.

Bridle Lake: Drilling in 1979 by Amok intersected 0.112% U308 from 17.2 to 18.7 metres (CAR 316A) and 0.12% U308 from 52.6 to 53.0 metres (CAR 278).

Middle Lake: Recent exploration targeted VTEM, gravity and radon targets. The targets are located in the up-ice direction of historical high-grade boulder trains found by prospecting with grades of up to 16.9% U3O8.

Recent exploration by ALX's predecessor companies

2014

A ground gravity survey was carried out on three grids at Middle Lake, consisting of approximately 1,600 stations.

A 20-hole, 2,000 m diamond drill program tested the gravity, radon, helium, geochemical, and magnetic anomalies and VTEM conductors identified on the property. The drilling was extended to 3,287 m in 31 holes to better assess encouraging alteration and anomalous radioactivity encountered in the Donna Zone, immediately west of Skull Lake (see Alpha Exploration Inc. news release dated April 1, 2014).

2015

A 17-hole, 1,850 m diamond drilling program at Middle Lake was a continuation of the 2014 diamond drilling program and tested geophysical features in the northern part of the property near Skull Lake. Targets were chosen following the integration of gravity, electromagnetic and magnetic features. An area hosting an expansive historical radon anomaly and scattered high-grade uraniferous boulders located immediately to the south and west of the area was also tested (see Alpha Exploration Inc. news release dated March 10, 2015).

Geophysical targets were corroborated by drilling. Conductors intersected west and north of Skull Lake are related to sulfide-bearing graphitic shear zones in psammitic gneiss with pegmatite in contact with Archean Earl River gneiss complexes. Farther to the west, a large gravity low anomaly was explained by the presence of abundant Cluff Lake impact breccia containing local graphitic shear zones. No significant mineralization was intersected.

Historical exploration by ALX's predecessor companies

Middle Lake

ESO Uranium Corp. ("ESO”), a predecessor company of ALX, acquired the property with Acme Resources Inc. in 2004. Previous work includes:

2006 ESO carried out Max‐Min HLEM and MEGATEM surveys (see ESO news release dated October 29, 2006).

2007 ESO completed a detailed radon in soil gas survey southwest and northwest of Skull Lake where historically anomalous radon values had been obtained by Amok in 1982‐83 (Powell, 1985). Samples were collected at 25 m intervals along 4 lines spaced 100 m apart. 45 samples were collected in the southwest area and 5 in the area northwest of Skull Lake. Radon values for the 50 samples collected showed a maximum value reaching 46 cpm (see ESO news release dated March 5, 2007).

2012 Special Projects Inc. was commissioned by ESO to fly a 6,475 line-km high-resolution magnetometer and radiometric airborne survey. The survey was flown along east‐west lines spaced 50 m apart and on north‐south tie lines 500 m apart. The magnetometer survey showed sharp contrasts between magnetic highs, interpreted as Archean granites, and magnet lows, interpreted as Paleoproterozoic metasedimentary rocks. The survey helped to define a number of extensive magnetic low ‘basins’ on the property. Interpreted structural features have predominant NNE and NW directions as well as some E‐W features.

2013 Alpha Exploration Inc. ("Alpha") carried out a helicopter-borne VTEM survey over the Middle Lake property by Aeroquest Airborne. The 310 line-km survey was flown along northeast (040° azimuth) to southwest lines spaced 100 m apart with tie lines flown perpendicular to these at 1000 m spacing. The survey identified a number of generally northwest‐trending, trough-type EM anomalies, which are possibly related to basement conductivity and most likely to graphitic zones. The conductors are generally subparallel to the northwest geological trend and airborne magnetometer trends.

Coincident radon and helium surveys were carried out at the up-ice termini of two historic radon anomaly trends and mineralized boulder dispersion fans. These were the Donna (Lac Hubert – Skull Lake) fan and the Middle Lake fan, which were referred to as the West and East grids respectively. RadonEx carried out the radon sampling program with 409 samples collected from soil gas, muskeg water, and lake water and sediment. Samples were generally collected at 50 m spacings along lines spaced 50 m apart. The high-density sampling area west of Middle Lake was sampled on a 25 m grid spacing. Radiometric readings with a hand held Exploranium GR-110 were also collected at all of the land and muskeg sample locations. Petro‐Find Geochem Ltd. carried out the initial helium sampling program in August and a follow-up program in October 2013. In all, 557 samples were collected (375 in August, 182 in October) and analyzed for helium as well as hydrogen and neon. The reason for carrying out such a survey is because these gases can be related both directly and indirectly to uranium mineralization. Several promising helium anomalies were obtained on both the East and West grids. The spatial association of radon and helium anomalies corresponds geographically with the up ‐ ice termini.

Gorilla Lake

2006 ESO's drilling encountered extensions to the known mineralization intersected by Amok in 1979 (0.85% U3O8 over 2.3 meters in hole CAR 425) in 2 of the 8 holes drilled. Drill hole CLU‑01 intersected 0.46% U3O8 over 1.5 m from 174.0 to 174.5 metres. Drill hole CLU‑07 intersected two zones of uranium mineralization: one zone returned 0.17% U3O8 over 7.0 metres from 153.0 to 160.0 m, including 0.82% U3O8 over 1.0 metre and a second zone contained 0.20% U3O8 over 2.0 m from 175.0 to 177.0 metres. These step-out holes confirmed the presence of uranium in the area of Amok's hole CAR-425 (see ESO news release dated May 1, 2006).

Bridle Lake

2005 ESO completed a MEGATEM® II airborne geophysical survey. The survey consisted of 2,052 line-km flown at 400-metre spacings and was designed to locate known conductors which trend on to the Cluff Lake properties from the neighboring Shea Creek Project (UEX/AREVA) (see ESO news release dated October 17, 2005).

2006 A horizontal loop EM survey was completed over two grids totaling 58 line-km to refine and further delineate numerous conductors detected by the 2005 MEGATEM survey (see ESO news release dated October 29, 2006).

2007 ESO completed a detailed radon in soil gas survey that identified two radon anomalies.

ESO completed a 27-hole drill program where 9 holes intersected radioactivity (see ESO news release dated October 17, 2007). A further 7 holes were completed in the fall of 2007 for a total of 4,796 metres of core drilling.
