SNOWLINE GOLD CORP announced analytical results from additional exploration holes drilled during its 2023 exploration campaign in Canada's Yukon Territory. The hole was drilled to the southeast, making it the first meaningful test of continuity in a direction other than the southwest and northeast azimuths of previous holes. Holes V-23-068 and V-23-069 were drilled in the northeastern part of the target, extending the boundary of strong gold mineralization which remains open in this direction and will be targeted as part of the upcoming 2024 drill campaign at Valley.

Highlight summary of Snowline's latest assay results. Interval widths reported; true widths of the system are not yet known. In addition, the Company will commence an advanced round of metallurgical testing in First Quarter 2024 to assess optimal processing methods and to quantify processing parameters that will assist in future economic assessments of the Valley target.

This testing will primarily use material from a PQ-sized hole drilled as a near twin to V-23-066.

This hole demonstrates the consistency of mineralization at Valley regardless of drill hole orientation along with continuity of mineralization between previous, parallel holes.

Note that the entire hole is mineralized, with a zone of >1 and >2 g/t Au assays within the final 70 m of the hole, at depth in the southeastern part of the system. The hole begins in coarse-grained granodiorite and remains in coarse-grained granODiorite for its entire length, with minor xenoliths and intrusive breccias locally. quartz vein density is low (averaging 5 veins/metre) and decreases downhole, though this is in part an artifact of the low angle of quartz veins to drill core.

Strong mineralization continues to the end of the hole at 386.0 m. Plan view of the Rogue Project's Valley target showing analytical results from previous and current drilling, along with drill traces of outstanding holes. The consistency of strong mineralization on the target is reinforced by the capped values in the rightmost column, wherein any assay result >10 g/t Au is replaced by 10.0 g/t Au to calculate the average interval grades. The hole remained in the fine-grained intrusive rock until its termination at 484 m. Analytical results have been received for an additional four holes from a Phase I drill program on the Yarrow target at Snowline Gold's Tosh Project, an orogenic gold project located in the southwestern Yukon.

This program represents the first-ever drill testing anywhere on the broader Tosh project area. Localized, elevated gold values (0.10 to 0.72 g/t Au) were present as rare, generally discrete intervals in all four holes, variously associated with faulting, brecciation and alteration of sedimentary host rocks. The results demonstrate the presence of an orogenic-type gold system.

The higher gold and silver grades encountered in surface sampling have yet to be explained by drilling, and multiple kilometers-scale geochemical anomalies at Tosh remain untested by any drilling to date. Tosh covers a series of untested, kilometers-scale orogenic gold targets with geological similarities to the White Gold district roughly 100 km to the north. Resource figures shown are based on public disclosure from third parties and have not been verified by the Company.

On receipt from the drill site NQ2-sized drill core was systematically logged for geological attributes, photographed and sampled at Snowline's 2023 field camp. Sample lengths as small as 0.5 m were used to isolate features of interest, but most samples within moderate to strong mineralization were 1.0 m in length; otherwise, a default 1.5 m downhole sample length was used. Core was cut in half lengthwise along a pre-determined line, with one half (same half, consistently, dictated by orientation line where present or by dominant vein orientation where absent) collected for analysis and one half stored as a record.

Field duplicates were collected at regular intervals as ¼ core samples by splitting the ½ core sent for sampling, leaving a consistent record of half core material from duplicate and non-duplicate samples alike. Standard reference materials and blanks were inserted by Snowline personnel at regular intervals into the sample stream. Bagged samples were sealed with security tags to ensure integrity during transport.

They were delivered by expeditor to Bureau Veritas' preparatory facility in Whitehorse, Yukon. Sample preparation was completed in Whitehorse, with analyses completed in Vancouver. Similar procedures were employed on the Tosh Project, though drill core was transported to Whitehorse in advance of detailed logging and sampling.

Bureau Veritas is accredited to ISO/IEC 17025 and ISO9001 for quality management. Samples were crushed by BV to >85% passing below 2 mm and split using a riffle splitter. 250 g splits were pulverized to >85% passing below 75 microns.

A four-acid digest with an inductively coupled plasma mass spectroscopy (ICP-MS) finish was used for 59-element analysis on 0.25 g sample pulps (BV code: MA250). All samples were analysed for gold content by fire assay with an atomic absorption spectroscopy (AAS) finish on 30 g samples (BV code: FA430). Any sample returning >10 g/t Au was reanalysed by fire assay with a gravimetric finish on a 30 g sample (BV code: FA530).
