Galiano Gold Expands Abore Drilling Program After High‑Grade Results, Aiming for Maiden Underground Resource in February 2026

Galiano Gold Inc. reported that its 2025 Abore drilling program has produced multiple high‑grade intercepts, including 4.7 g/t Au over 28 m and 3.5 g/t Au over 17 m, confirming that mineralization continues well below the existing reserve. These results validate the geological model that underpins the company’s strategy to define a maiden underground resource at Abore.

The company will add 11,000 m of drilling to the program at a cost of $3.1 million, expanding the exploration footprint and accelerating the definition of the underground resource expected in February 2026. The additional drilling will target both open‑pit extensions and deeper underground zones, providing a more comprehensive understanding of the deposit’s geometry and grade distribution.

Galiano’s focus on Abore is part of a broader plan to extend the life of the Asanko Gold Mine and increase production in the second half of 2025. By securing a larger underground resource, the company can shift from surface to underground mining, which typically offers more consistent grades and lower operating costs per ounce. The expansion also aligns with Galiano’s self‑funded growth model, as the company has maintained a strong balance sheet with significant cash reserves and no debt.

Vice President of Exploration Chris Pettman said the results “validate our exploration strategy and strengthen our confidence in Abore as we advance with expanded drill programs targeting both open‑pit extensions and underground potential.” He added that the company anticipates continuing aggressive drilling operations at Abore for the remainder of 2025 and into 2026.

The high‑grade intercepts and the confirmed continuity of mineralization below the reserve suggest that the deposit’s resource base is larger than previously estimated. A larger underground resource will enable Galiano to increase its production volume, improve economies of scale, and potentially lower its all‑in sustaining cost per ounce. The company’s focus on underground mining also positions it to benefit from the current high gold price environment, which enhances the economic viability of deeper, higher‑grade ore bodies.

Galiano has recently addressed operational challenges at the Asanko mine, including the commissioning of a secondary crushing circuit in July 2025 and improvements to its milling process. These operational gains, combined with the new drilling results, reinforce the company’s trajectory toward higher production and stronger cash flow generation. The company’s continued investment in exploration, coupled with its robust financial position, supports a positive outlook for the near‑term and long‑term value creation of the Abore deposit.
