Cannon Copper

On January 7, 2021, ALX announced an exploration review on its 100%-owned Cannon Copper Project (“Cannon Copper”, or the “Project”) located in Kamichisitit Township within the Sault Ste. Marie Mining District of Ontario, Canada. Cannon Copper hosts the historic Cannon Copper Mine and Mill (also known as the Crownbridge Copper Mine), which saw limited copper processing in the late 1960s and early 1970s.

On July 13, 2021, ALX announced the commencement of a helicopter borne airborne electromagnetic (“EM”) survey at Cannon Copper. The airborne EM survey will consist of 194 line kilometres at 150-metre spacing utilizing the helicopter-borne Vertical Time-Domain Electromagnetic (“VTEM™ Max”) system from Geotech Ltd. of Aurora, Ontario, Canada. The VTEM™ Max system offers a high degree of depth penetration and represents the first modern airborne EM system flown on the Project.

Following completion of the VTEM™ survey, ALX is planning its first site visit to Cannon Copper since 2013. New geophysical targets detected by the airborne survey will be followed up in the summer of 2021 by prospecting, the use of leading-edge geochemical and ground geophysical surveys, and future diamond drilling on new target areas. 

ALX maintained 100% ownership since 2015 of thirteen claim units at Cannon Copper totaling 289 hectares (714 acres) following the amalgamation of Alpha Exploration Inc. and Lakeland Resources Ltd. The Company has staked an additional 104 units since October 2020 and has expanded the size of the Project to 117 cell units totaling 2,600 hectares (6,425 acres).

Highlights of the Cannon Copper Project

  • Cannon Copper is located approximately 33 kilometres (20 miles) northwest of Elliott Lake in an exploration district known for high-grade copper occurrences both on surface and in drill holes, but the area remains underexplored for base metals in the modern era.
  • The Project is accessible by way of paved highways connecting to secondary roads and trails, and has an active powerline.within the south end of the property boundary.
  • The past-producing Cannon (Crownbridge) Copper Mine and Mill operated intermittently as a regional copper processing facility from 1966 until 1972. Production statistics for the Cannon Copper property are unknown. The Ministry of Energy, Mines and Northern Development of Ontario currently lists a historical mineral resource for the Cannon Copper Mine of 415,000 tonnes grading 1.8% copper over a width of 6.5 feet (1.98 metres) (Note: This historical resource is not compliant with the standards of National Instrument 43-101 - see “National Instrument 43-101 Disclosure” below for additional cautionary language).1
  • Copper mineralization was traced historically along a strike length of approximately 2.68 kilometres (1.6 miles) within quartz veins and conglomerates, in a series of mineralized zones at depths ranging from near-surface to approximately 300 metres (984 feet).2
  • A single deep hole (hole CR-15) drilled by Crownbridge Copper Mines Limited in 1963, intersected chalcopyrite mineralization within argillitic rocks beginning at a depth of 580.34 metres (1,904 feet), located well below the quartz vein-hosted copper mineralization forming the identified mineralized zones. Historical operators recommended follow-up to hole CR-15 to test for new sedimentary-hosted copper resources, but no follow-up deep drilling was carried out.3

ALX is conducting a review of geophysical data available in the public domain to apply new modelling techniques to existing data. New geophysical targets that could be related to the historical mineral occurrences at Cannon Copper are planned to be followed up in the summer and fall of 2021 by prospecting, the use of leading-edge geochemical and ground geophysical surveys, and future diamond drilling, if warranted.

About Cannon Copper

The Cannon Copper property is underlain by the Gowganda Formation which is part of the Proterozoic Huronian Supergroup metasedimentary rocks of the Southern Province. Mineralization consists of chalcopyrite and pyrite, both disseminated and massive, in structurally-controlled quartz veins and in the quartz breccia zone alongside the quartz veins, with minor disseminated bornite. Minor gold values have been reported in some zones. Alteration of the host Gowganda Formation consists of chlorite, chlorite/silica, hematite and hematite/silica alteration.

Exploration is recorded from 1956 by Great Lakes Copper and later by Andover Mining & Exploration Ltd. (“Andover”) from 1958 to 1960. Andover drilled 75 holes for a total of approximately 9,185 metres (30,133 feet), which outlined the mineralized zones on the property to an approximate depth of less than 150 metres (500 feet). In 1963, Crownbridge Copper Mines Limited acquired the property and drilled an additional 11,910 metres (39,077 feet) in both shallow and deep holes, testing for mineralization to a depth of over 580 metres (1,900 feet). In 1968, Cannon Mines Ltd. (“Cannon”) acquired the property, sank a 245-metre (800-foot) decline and began processing material in a newly-erected mill. For unknown reasons, Cannon ceased all operations in 1972. Other companies in the early 1970s made attempts to restart operations but no further development or mineral production is recorded after 1975. A predecessor company of ALX acquired the Cannon Copper property in 2012.

National Instrument 43-101 Disclosure

The technical information on this web page has been reviewed and approved by Sierd Eriks, P.Geo., President and Chief Geologist of ALX, who is a Qualified Person in accordance with the Canadian regulatory requirements set out in National Instrument 43-101. The historical mineral resource estimate quoted on this web page uses categories that are not compliant with National Instrument 43-101 ("NI 43-101") and cannot be compared to NI 43-101 categories, and is not a current estimate as prescribed by NI 43-101. Readers are cautioned that a Qualified Person has not done sufficient work to classify the estimate as a current resource and ALX is not treating the estimate as a current resource estimate.

Geochemical results and geological descriptions quoted on this web page were taken directly from assessment work filings published by the Government of Ontario. Management cautions that historical results were collected and reported by past operators and have not been verified nor confirmed by its Qualified Person, but create a scientific basis for ongoing work in the Cannon Copper area. Management further cautions that past results or discoveries on adjacent or nearby mineral properties are not necessarily indicative of the results that may be achieved on ALX’s mineral properties.
