Gold Hart Copper and Rhyolite Resources Enter into Definitive Arrangement Agreement; Gold Hart Completes Diamond Drill Hole at Tolita Gold-Copper-Moly-Silver Asset in Vicuna District of Chile

• On 7 Apr 2026 Gold Hart Copper entered a definitive arrangement agreement to acquire 100 % of Rhyolite Resources Ltd. in exchange for 1 HART share for every 2.6 RYE shares.
• The deal is slated to close in late Q2 2026, subject to shareholder and regulatory approvals.
• The transaction follows an oversubscribed $18.6 M private‑placement financing (closed 16 Mar 2026) that fully funds the acquisition and accelerates exploration at Tolita and Nessa.
• Drilling updates: completion of a 1,051 m diamond hole (TOLDDH01) with ~700 m of continuous porphyry‑style veining; another hole (TOLDDH04) reached 551 m. Plans to start reverse‑circulation (RC) drilling on a high‑grade trench that previously returned ≈52 g/t Au‑eq over 10 m.
• A comprehensive geochemical survey at the Nessa Complex has yielded multiple high‑grade samples (up to 9.7 g/t Au, 4.73 % Cu).

• Acquisition: Adds Rhyolite’s land package and existing work‑programs to Gold Hart’s balance sheet, expanding its Chilean footprint and eliminating a separate corporate structure. The all‑stock consideration dilutes shareholders but is priced at a modest 0.26 $ per unit (via the earlier financing), implying limited cash outlay.
• Financing: The $18.6 M raise was already closed; the acquisition therefore does not create immediate cash strain and confirms that the company is fully funded for its near‑term drill campaign.
• Exploration upside: The newly completed deep hole at Tolita demonstrates a thick interval of porphyry mineralisation, reinforcing the geological model and de‑risking the flagship asset. High‑grade surface trench results (≈52 g/t Au‑eq) suggest a potentially valuable shallow component that can be tested quickly with RC drilling.
• Overall: The combination of a strategic acquisition, fully funded balance sheet, and encouraging drill results constitutes a material positive development relative to prior expectations. It moves the company from an “exploration‑only” stage toward a multi‑asset platform with near‑term upside potential.

Gold Hart Copper Corp. is a junior exploration company focused on porphyry systems in Chile’s Vicuña District (Tolita) and the Domeyko Fault System (Nessa Complex). Tolita hosts gold‑copper‑molybdenum‑silver mineralisation with both deep, large‑scale porphyry potential and a shallow high‑grade trench. Nessa is a newly expanded 13,500 ha land package with historic surface Au‑Cu‑Ag shows.
