VANCOUVER, CANADA – November 2, 2026: Golden Goliath Resources Ltd. (“Golden Goliath” or the “Company”) (TSXV: GNG). The Company is pleased to announce that it has executed a Joint Venture Agreement with IMEX International S.A.E. https://imexegy.com/ (“IMEX”) and Nexgold International Mining Company (“Nexgold”) to explore and develop the Um Garayat Block B and Block D Concessions in Wadi Al-Alaqi in the Eastern Desert, in the Republic of Egypt. Golden Goliath and Nexgold will be responsible for all operating and capital costs, while Nexgold will act as the in-country Operator on behalf of the Joint Venture. The Um Garayat Block B and Block D partnership is comprised of IMEX 50%, Golden Goliath 40%, and Nexgold with 10%.

IMEX International is a leading commodity trading company in Egypt. IMEX is one of the largest petroleum and natural gas traders in Egypt. In recent years IMEX has built a substantial position trading Egyptian phosphate. IMEX’s precious metals mining footprint includes the Umm Garayat Block B & D Concessions, representing the company’s expansion into gold exploration and production.

The Um Garayat Block B & Block D Concessions are highly prospective for gold. There has been a long, at least, 4,000-year history of mining in this area dating back to the times of the Pharaohs. Most recent mining activities include artisanal gold production and limited commercial mining that began in the early Twentieth Century but was suspended during the 1950s. The combined area covered by these blocks is approximately 245 square kilometres, having easy access, by sealed road, and located about 150km from the regional capital, Aswan. The Partnership intends to review the current artisanal mining operations to determine how best to expand these and to undertake an exploration campaign across the rest of the Concessions over the coming years.

Location: Um Garayat Block B and Block D

The Um Garayat Concessions are located in southern Egypt in Wadi Allaqi, a prolific gold hosting region of upper Egypt. The Um Garayat blocks contain both extensive alluvial gold and hard-rock deposits which are currently being mined by local companies using traditional artisanal mining techniques. The area also shows extensive historical mining activities including adits, shafts, dumps and tailings primarily dating back to the beginning of the twentieth century. There are a number of important gold deposits contained within the concessions: The Um Garayat, Heimur, and Nile Valley historic gold mines. Gold mineralisation here occurs as nests and pockets within and associated with gold-bearing quartz veins that have been worked at depth from eight inclined and vertical shafts and wings linked together by levels driven laterally at depths of 32, 60 and 96 meters.

The Agreement is considered a related-party transaction pursuant to Multilateral Instrument 61-101, as the Company’s CEO, Maki Petkovski, is a director and officer of Nexgold. The Agreement is exempt from the need to obtain minority shareholder approval and a formal valuation as required by and under applicable provisions of MI 61-101 as each party will share pro rata in the Partnership.

“The addition of these exploration blocks to our portfolio increases our opportunities within this highly prospective gold producing province. Furthermore, it is an honour to join IMEX as their strategic partner and operator of choice within the Egyptian mining sector” said Golden Goliath CEO, Mr. Petkovski.

The scientific and technical content of this news release has been reviewed and approved by Maki Petkovski, a Qualified Person (QP) as defined by National Instrument 43-101.
