GOLDCLIFF CONFIRMS FREE GOLD AT KETTLE VALLEY NORTH CLIFF ZONE, ASSAYS UP TO 2.70 G/T AU AND 29.2 G/T AG

Goldcliff Resource Corp. has confirmed the presence of free gold, and possible electrum, from sampling conducted in November, 2025, at its Kettle Valley gold-silver project near Rock Creek, B.C.

A total of 28 rock samples collected from bedrock and subcrop returned assays of up to 2.70 grams per tonne gold and 29.2 g/t silver, with multiple samples demonstrating anomalous to elevated gold values.

Sample analysis highlights

All samples were initially analyzed using fire assay and four-acid digest ICP methods. Following the identification of discrete, fine grains of free gold and possible electrum, select samples were further analyzed using PhotonAssay, a non-destructive technique increasingly utilized by major mining companies and accredited laboratories.

Subsequently, eight samples were subjected to 50-gram metallics assays, which confirmed the presence of free gold in several samples:

• Seven of 28 samples returned greater than 0.25 g/t Au;
• Three samples returned 0.82, 1.29 and 2.70 g/t Au (fire assay).

The presence of free gold has potentially positive metallurgical implications.

Kettle Valley project overview

Kettle Valley is emerging as a new, epithermal gold-silver prospect with mineralization occurring as discrete grains of free gold and possible electrum. Only a very minor amount of sulphide minerals, mainly pyrite, is present. Interestingly, geochemical analysis indicates a lack of any deleterious elements. A key feature of the Kettle Valley project is that gold/silver mineralization spans all lithologies and ranges from quartz veining, quartz stockwork and quartz-carbonate breccias. Intense faulting throughout the property has likely provided the numerous hydrothermal pathways for mineralization in this low-sulphidation mineralized system.

North Cliff zone expansion potential

At the newly defined North Cliff zone, gold-silver mineralization has been identified over an area measuring approximately 250 metres (north-south) by 150 metres (east-west), with a vertical extent of over 80 metres (850-metre to 930-metre elevation).

This zone represents a priority target for continued surface work and follow-up exploration.

Continuing exploration program

A field crew is completing activity on the property, advancing detailed surface work aimed at refining drill targets.

Given the shallow overburden, the program is focused on:

• Hand-dug open cuts (ranging from several metres to over 20 metres in length);
• Detailed geological mapping;
• Continuous surface exposure of mineralized zones.

This work is expected to improve the understanding of mineralization controls and refine future drilling programs.
