ALPHA COPPER CORP, OPTION PARTNER TO THE INDATA PROPERTY, ANNOUNCES RESULTS OF RECENT AIRBORNE GEOPHYSICAL SURVEY

Eastfield Resources Ltd. partner Alpha Copper Corp. has released results of the high-resolution airborne magnetic gradient, radiometric and very-low-frequency/electromagnetic survey at the Indata project, located in central British Columbia, under option from Eastfield Resources Ltd.

The Indata project encompasses 3,189 hectares (7,880 acres) and is located 230 kilometres northwest of the city of Prince George and immediately south of the Stardust-Kwanika project, owned by Northwest Copper Corp. Alpha Copper may earn a 60-per-cent interest by completing $2.3-million in exploration and paying $450,000 (cash and/or shares) by June 20, 2024.

Highlights:

• The new magnetic and radiometric data set is a great improvement over historical data sets and will be interpreted to generate new drill targets.
• The magnetic survey shows high-resolution details of a magnetic anomaly associated with copper mineralization in the Lake zone, where previous results include IN22-82, with 173.6 metres grading 0.23 per cent copper starting at 2.9 metres, including 28.9 metres grading 0.47 per cent copper starting at 2.9 metres. It constitutes the northern boundary of the Lake zone, which remains open beyond this point.
• A new zone of molybdenum mineralization was unexpectedly discovered in 2022 five kilometres to the south of the Lake zone in what is now called area 74, where hole IN22-74 intersected 30.8 metres grading 0.10 per cent molybdenum (0.16 MoS equivalent) starting at 113.7 metres and continuing to the bottom of the hole, including 7.5 metres grading 0.32 per cent molybdenum (0.51 per cent MoS equivalent).
• The magnetic survey shows linear features associated with both the polymetallic (Cu-Au-Ag (copper-gold-silver)) vein zone and the 74 zone (Mo, discovered in 2022). The former feature can be followed over a three-kilometre strike length and the latter over 2.5 kilometres with the new geophysics.
• The magnetic survey was flown using a gradient magnetic system by Precision GeoSurveys over an area of 44.1 square kilometres.
• The company is currently preparing for a 3-D IP (induced polarization) survey on the Lake zone and Precious Metal vein zone to complement the data and further define drill targets.

Alpha Copper flew the entire Indata claim block at 100-metre spacing using a Precision Geosurveys gradient magnetic system. This system uses three magnetometers to measure the gradient of the magnetic field and collects superior data. At the same time, the helicopter is fitted with sensors to collect VLF and radiometric data. The data set will be further interpreted to identify faults, shears and alteration patterns that may lead to additional and refined drill targets.

Information on the location, geology and history at the Indata project is available on the company's website.

Other projects

Zymo: copper-gold porphyry system with several one-kilometre-scale targets within an eight-kilometre-long induced polarization feature. Zymo is located 45 kilometres west of Smithers, B.C., and is 100 per cent owned. Results include drill holes ZY08-07, with 0.72 per cent copper and 0.66 gram per tonne (g/t) gold over 72 metres, and hole ZY11-20, with 0.28 per cent copper and 0.34 g/t gold over 126 metres. Peripheral precious metal veins have returned up to 10.78 g/t gold. Zymo is fully permitted.

Iron Lake: copper-gold-palladium-platinum-cobalt, located 40 kilometres northeast of 100 Mile House in British Columbia. The project is optioned to Tech-X Resources Inc. (a private company headed by Haig Farris). Targets include ultramafic copper-gold-palladium-platinum-cobalt and porphyry copper-gold. Tech-X may earn an 80-per-cent interest in Iron Lake by completing a total of $12-million in work and paying a total of $1-million in option payments by Dec. 31, 2027. Induced polarization surveying continued through the winter and spring (2022), with 23 drill diamond drill holes (5,001 metres) completed thereafter. Analytical work continues and an aggressive program is planned for 2023, beginning with a VTEM airborne geophysical survey, which was flown in March to focus targets interpreted from results obtained in 2022 and planned for drilling in 2023.

Hedgehog: copper-gold (VMS) and lode gold, located approximately 12 kilometres north of the community of Barkerville, B.C. In 2021 option partner West Oak Gold Corp. discovered several new soil anomalies (arsenic, zinc and copper). Further soil sampling completed in 2022 has defined a previously unknown cohesive arsenic-copper soil anomaly with sporadic soil gold values to 748 parts per billion. Intriguing to the potential of Hedgehog are several historic float samples, including a massive sulphide boulder grading 24.3 per cent copper and 19.6 g/t silver discovered in 1999, and five additional copper-rich massive sulphide boulders with an average grade of 8.0 per cent copper and 8.9 g/t silver discovered in 2000. Other companies active in the area include Osisko Development, which is conducting a major exploration program for gold 10 kilometres to the south in and around the former operating Barkerville gold mine, the Cariboo gold project. Hedgehog is fully permitted.

CR: gold, located approximately 80 kilometres northeast of the town of Quesnel, B.C., and 20 kilometres north of the gold mining towns of Wells and Barkerville, acquired by staking in 2014. There is no record of hard rock mineral exploration on the CR property prior to Noranda Exploration carrying out regional exploration in the area in 1986, identifying a 1.2-kilometre-by-0.7-kilometre arsenic-in-soil anomaly surrounding a local drainage which it named Arsenic Creek. Eastfield subsequently completed surface soil and rock sampling, and induced polarization surveying, and an initial single drill test in the 2022 field season.
