Avidian Gold Corp. Re-Assays Amanita Results Using Metallic Screen Analysis to Fort Knox Gold Mine
TORONTO, January 7, 2020 - Avidian Gold Corp. ("Avidian" or the "Company") (TSXV:AVG) is pleased to report the results from its re-assaying of the 2019 Trenching program at its Amanita property. The Amanita property is comprised of State of Alaska claims totaling 1,460 hectares (14.6 sq. km) and is located 15 km northeast of Fairbanks, Alaska, and approximately 5 km southwest and contiguous to the Fort Knox open-pit gold mine (Figure 1).
During the summer of 2019, Avidian carried out an exploration program whereby a total of six trenches were excavated for 1,725 m with 722 samples collected with variable sample lengths of 1.5 m or 3.0 m depending on prospective geology. Initially samples were assayed using a standard fire assay analysis (October 21, 2019 release), however recognizing that visible gold occurs on the property, selected samples were re-assayed using metallic screen analysis. This analytical technique utilizes a larger sample size and also determines the concentration of free gold within the coarse fraction of the sample.
The table below provides a comparison of the October 21, 2019 results versus the re-assay results both on an uncut and top cut to 20.0 g/t Au as two individual samples returned 52.6 g/t Au and 27.3 g/t Au. The main intersection is now 94.5 m of 3.04 g/t Au (uncut) or 2.01 g/t Au (cut), including 22.5 m of 1.51 g/t Au (uncut) or 7.16 g/t Au (cut).

* Not previously reported. Trench E not completed, Trench F abandoned. True widths of each mineralized zone have yet to be clearly established.
Ninety seven (97) samples were re-analyzed dominantly within the known mineralized trends as reported in the October 21, 2019 press release as well as other selected samples outside these mineralized trends. All the major mineralized intervals were re-assayed using the metallic screen technique, as were any samples containing elevated bismuth values (greater than 10 ppm), as there is a direct association of elevated bismuth with gold.
Dave Anderson, Chairman and CEO of Avidian states " Our prospecting crews have noted visible gold on the Amanita property on several occasions. This combined with the knowledge of historical placer mining and blaster analysis results completed by Kinross in the late 90's indicated the need for metallic screen analysis. Not surprisingly the new analyses confirmed the coarse gold content and translated into a significant increase in the reported grades. Going forward all assays returning elevated bismuth results will be reassayed using the metallic screen analysis. We look forward to following up on these results and exploring the entirety of the Tonsina Trend in our 2020 summer drilling and trenching programs".
The objective of the 2019 trenching program was to expose and sample a portion of the Tonsina Trend which is a fault bounded, 800 metre wide, northeast trending structural corridor that can be traced along a strike length of approximately 4 km on the property. This corridor trends directly into Kinross's Fort Knox open-pit mine which produced over 255,000 ounces of gold at a mill grade of 0.50 g/t Au (Kinross press release, Feb 13, 2019). The mineralization at Fort Knox is associated with this northeast structural corridor (see Figure 1).
The Tonsina Trend has been sparsely drilled with 39 historical reverse circulation holes, of which 30 intersected oxide mineralization with grades > 1.0 g/t Au such as: 13.72 m of 3.02 g/t Au, 10.67 m of 1.08 g/t Au, 12.19 m of 2.28 g/t Au, 4.57 m of 11.49 g/t Au, and 3.05 m of 14.04 g/t Au. This previous drilling has only tested a portion of the Tonsina Trend (see Figure 2) to a depth of less than 150 m with the gold mineralization currently believed to be a series of steeply dipping oxidized bodies hosted within metamorphosed sediments proximal to intrusive Cretaceous age rocks. This setting is similar to Kinross's Gil project where gold mineralization occurs in quartz-sulphide and quartz-carbonate veins, clay-filled shear zones, and limonite-stained fractures, which crosscut nearly all lithologies. Gold mineralization is widespread, but both gold grade and continuity are related to complex interactions among hydrothermal fluids, host rocks, and structure (June 11, 2018 NI 43-101 Kinross Technical Report).
The 2019 trenching program was designed to delineate and map structures, geology and mineralization that may be related to the historical drill holes in order to establish the best orientations for a follow-up diamond drill program. The gold mineralization encountered in the trenches is associated primarily with N70W and N005 to 010E striking, high angle Quartz-Iron Oxide veins/shears/faults that also contain elevated arsenic, bismuth and antimony. The highest gold values are associated with elevated bismuth (> 10 ppm to 870 ppm). Vein widths range from 2 cm to 2 m. The intersection of 94.5 m of 3.04 g/t Au that occurs in Trench C, which trends due north, is hosted in mineralized structures trending from 003º to 055º and dipping steeply in variable directions. The results from trenches C & D in relation to the historical RC holes are shown in Figure 3 which highlights the wide distribution of gold mineralization greater than 1 g/t Au. While many of the mineralized zones are associated with veins/shears/faults, significant intersections can also be found within the metamorphosed sedimentary host rocks such as the 27.0 m of 4.22 g/t Au found in trench D.
The grades of the mineralized intersections encountered in the trenches are significant when compared to the resource cut-off grade at the adjacent Fort Knox mine (0.10 g/t Au) and at the Gil Project (0.21 g/t Au) (NI 43-101 Kinross Technical Report dated June 11, 2018). Also, the discovery of NW trending mineralized veins is important given that historical drilling was mainly in a NW direction; it appears that future drilling should be designed to intersect the mineralized NW structures.
The trench results combined with the historical drilling highlights the wide distribution of gold mineralization with significant widths and grades within the 4 km long Tonsina Trend. Avidian is currently compiling the results of the 2019 trenching program with the historical information in preparation for a follow-up drill program that is anticipated to test the full length and width of the Tonsina structural corridor on the Amanita property.

Quality Control/Quality Assurance
Sampling included insertion of certified standards and blanks into the stream of samples for chemical analysis. Every twentieth trench sample was a standard or a blank. Samples were prepared at ALS Chemex's laboratory in Fairbanks, Alaska and shipped to their Vancouver facility for gold analysis by fire assay and other elements by ICP analysis for the October 21, 2019 reported results. ALS is a certified and accredited laboratory service. Original gold results varied from below detection to a high of 19.95 g/t. For the current re-assay program, approximately 1 kg of previously prepared reject material was analyzed by the metallic screen assay technique; results for total contained gold varied from below detection to 52.6 g/t.
