• Initiates soil & rock sampling on 100% Owned Northern Lights Copper
• Northern Lights' historic reports document copper mineralization grading 3% to 12% Cu
• Recent sampling confirms copper mineralization (1% to 19% Cu) over widths up to 4 meters at the surface
• Company adds to its copper-focused portfolio with option agreement on British Columbia copper/silver property

Toronto, Ontario--(Newsfile Corp. - October 1, 2024) - Global Copper Corp. (TSXV: CUCU) (FSE: WD9) ("Global Copper" or the "Company") is pleased to announce that it has initiated a property-wide soil and rock geochemical sampling survey on its 100%-owned, 485 hectare Northern Lights Copper Project (the "Project) in Nevada. The program is designed to test for and expand on the copper skarn mineralization that occurs on the property. Results from the survey will be used to identify zones to be tested by diamond and or reverse circulation drilling in the coming months. The objective of the Company is to confirm the deposit model with additional surface exploration work following by drilling to define a mineable high-grade copper deposit. The project is currently in the early exploration phase but planned drilling will confirm the grade, thickness and downdip extent of the mineralization confirmed at the surface. More details on the Company's flagship Northern Lights copper project are as set out below.

The Company is also pleased to announce that on September 25, 2024, the Company and an arm's length party (the "Optionor") entered into a property option and joint venture agreement (the "Agreement") pursuant to which the Optionor granted the Company an option (the "Option") to acquire several mineral titles located in British Columbia (the "Silver Vista Property"). In order to exercise the Option, the Company shall make the following payments:

1. Upon receipt of approval from the TSX Venture Exchange for the Option (the "Approval Date"), the Company shall pay the Optionor $10,000 and shall issue the Optionor 4,000,000 common share (the "Common Shares") in the capital of the Company at a deemed price of $0.05 per Common Share;
2. On or before the date that is the sixth month anniversary of the Approval Date, the Company shall pay the Optionor $10,000;
3. On or before December 31, 2025, the Company must incur $100,000 in expenditures on the Property and pay $20,000 to the Optionor;
4. On or before December 31, 2026, the Company shall pay $30,000 to the Optionor; and
5. On or before December 31, 2027 the Company shall pay $40,000 to the Optionor.

The Property is subject to a 2% net smelter return royalty (the "NSR") held by Amarc Resources Corp. ("Amarc") subject to the ability of the Company to purchase 1% of the NSR (resulting in the remaining NSR being 1%) for a purchase price of $1,000,000 at any time.

The Silver Vista property is located in northcentral BC, approximately 55 air kilometres ('km') northeast of the town of Smithers and 300 km NW of northern B.C.'s regional hub city of Prince George.

The Silver Vista property is comprised of approximately 48 square km (4,839.2 hectares) and was recently drilled in 2021 (9 holes over 1,507 metres). Drill hole SV21-07 intersected a continuous 0.62 per cent copper and 46-metre-long zone from 106 metres averages 48 grams per tonne silver. This zone included a 17-metre section containing 1.34 per cent copper and 94 grams per tonne silver. Along this zone as well, the highest copper grade of 2.57 per cent (112 to 113 metres) and the highest silver grade of 431 grams per tonne (121 to 122 metres) were assayed.

Stephen Dunn, President and Chief Executive Officer of Li3 Lithium, commented: "This acquisition adds to the Company's existing flagship Northern Lights Copper Project and furthers the Company's new strategy of focusing globally on copper exploration and project development. We see the energy transition to a net-zero carbon world as opportunity for mineral explorers to focus on the growth anticipated in demand for copper."

Nevada - Northern Lights Copper Project

Global Copper's 100%-owned Northern Lights Copper Project is located in the central portion of Nevada's well-known Walker Lane Trend about 25 kilometers (15 air miles) southeast of Yerington, Nevada (See Figure 2 below). The property consists of 58 lode mining claims covering 1200 acres (485 hectares) and is in close proximity to Nevada Copper Corporation's producing Pumpkin Hollow copper mine which has total resources in excess of 6.5 million lbs of copper equivalent. There are also several active copper exploration projects underway in close proximity to the property.

The Pumpkin Hollow ore deposit is characterized by an intense magnetic high as shown in Figure 3, which uses the same base map as Figure 2. The Northern Lights project is located between two magnetic highs in the eastern portion of the map (see Figure 3 below).

Mineralization observed on the property consists of: 1) massive magnetite, goethite, hematite, chalcopyrite replacement zones in the Triassic limestone and siltstone; 2) smaller, fracture- controlled zones of magnetite, goethite, hematite with copper oxide; and 3) disseminated pyrite, chalcopyrite, and copper oxides in sedimentary rocks as well as altered dacite porphyry. Visible copper oxide mineralization occurs in a northwest-trending zone approximately 1,500 meters long and 100 meters wide (5,000ft x 330ft). This replacement-skarn style of mineralization (deposit type) is similar to the nearby copper deposit at Pumpkin Hollow, currently in production by Nevada Copper Corporation.

Detailed geologic mapping by the Company and surface rock geochemical results confirm that Northern Lights has copper mineralization (1% to 19% Cu) over widths up to 4 meters at the surface. Review of historic reports dating back to the 1910 to 1920 era suggests that copper mineralization grading 3% to 12% Cu at an average width of 1 to 2 meters (2 to 6 feet) extends to a depth of 100 meters (325 feet). Underground workings are not accessible, and these grades cannot be confirmed without drilling.

The objective of the Company is to confirm the deposit model with additional surface exploration work following by drilling to define a mineable high-grade copper deposit. The project is currently in the early exploration phase but planned drilling will confirm the grade, thickness and downdip extent of the mineralization confirmed at the surface.
