Signal Gold Intersects 18.71 g/t Gold over 2.5 metres and 11.40 g/t Gold over 3.0 metres at the Goldboro Gold Project

TORONTO, ON / ACCESSWIRE / July 6, 2022 / Signal Gold Inc. ("Signal Gold" or the "Company") (TSX:SGNL)(OTCQX:SGNLF) is pleased to announce results from a recent drill program at its 100%-owned Goldboro Gold Project in Nova Scotia ("Goldboro" or the "Project"). The infill drill program, consisting of 3,865 metres in 31 diamond drill holes, was conducted to aide in the conversion of Inferred Mineral Resources within the East Goldbrook Pit into Indicated Mineral Resources (the "Infill Drill Program"). The existing constrained open pits outlined in the Phase 1 Open Pit Feasibility Study¹ were designed using only Measured and Indicated Resources, however they captured 975,000 tonnes of Inferred Mineral Resources at a grade of 2.11 grams per tonne ("g/t"), mainly in the East Goldboro Pit (Exhibit A). This represents an opportunity to positively impact Project economics by upgrading these Inferred Mineral Resources which are currently accounted for as waste tonnes.

Selected composited highlights from the Infill Drill Program include:

• 18.71 g/t gold over 2.5 metres (13.5 to 16.0 metres) including 85.30 g/t gold over 0.5 metres in diamond drill hole BR-22-354;
• 11.40 g/t gold over 3.0 metres (34.8 to 37.8 metres) including 60.50 g/t gold over 0.5 metres in diamond drill hole BR-22-345;
• 33.82 g/t gold over 1.2 metres (48.4 to 49.6 metres) in diamond drill hole BR-22-358;
• 1.36 g/t gold over 8.7 metres (20.3 to 29.0 metres) in diamond drill hole BR-22-349; and
• 3.91 g/t gold over 3.0 metres (169.0 to 172.0 metres) in diamond drill hole BR-22-370.

The results are important as they support the continuity of gold mineralization adjacent to existing Indicated Mineral Resources within the East Goldbrook Pit.

"As outlined in the Feasibility Study for the Goldboro Gold Project, we have identified significant opportunities to optimize the value of the Project and potentially increase the overall economics and longevity of the Project. This included the upgrading of Inferred Mineral Resources in the East Goldbrook Pit as well as exploring adjacent to, and along strike, of the existing Mineral Resource. We believe the results of the Infill Drill Program reported today may positively impact the Project's economics as the Inferred Mineral Resources being targeted are currently being accounted for as waste tonnes in the economics outlined in the Feasibility Study. Any Inferred Mineral Resources that we are able to convert would positively impact Project revenues and would reduce the strip ratio. The data gathered during the Infill Drill Program will be used in a future Mineral Resource Estimate anticipated to coincide with detailed engineering studies in 2023."

Drill holes BR-22-237 to BR-22-339 were drilled prior to holes BR-22-240 to BR-22-270, but were drilled for the purposes of testing mineralization, evaluating geotechnical properties as well as water testing. Assays for these holes have not been received and will be reported at a future date once data is available.

A table of selected composited assay results from the Infill Drill Program

• Intervals are reported as core length only. True widths are estimated to be between 70% and 100% of the core length.
• All drill hole results are reported using fire assay only. See notes on QAQC procedures at the bottom of this press release.
• All drill holes not reported in the table above did not encounter significant mineralization.
• Drill holes were oriented along a north-south trend with holes on the north limb of the hosting anticlinal structure drilled southward and holes located south of the anticlinal structure drilled northward. The dip of holes is dependant upon the location relative to the anticline with the goal of intersecting mineralized zones orthogonally.

Goldboro Gold Project - Mineral Resource Estimate

The Mineral Resource Estimate presented was prepared by Independent Qualified Person Glen Kuntz, P. Geo., of Nordmin Engineering Ltd. The Mineral Resource Estimate is based on validated results of 681 surface and underground drill holes for a total of 121,540 metres of diamond drilling completed between 1984 and the effective date of November 15, 2021, including 55,803 metres conducted by Signal Gold.

Mineral Resource Estimate for the Goldboro Gold Project - Effective Date November 15, 2021

* Combined Open Pit and Underground Mineral Resources; The Open Pit Mineral Resource is based on a 0.45 g/t gold cut-off grade, and the Underground Mineral Resource is based on 2.40 g/t gold cut-off grade.

Mineral Resource Estimate Notes

1. Mineral Resources were prepared in accordance with NI 43-101 and the CIM Definition Standards for Mineral Resources and Mineral Reserves (2014) and the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (2019). Mineral Resources that are not mineral reserves do not have demonstrated economic viability. This estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
2. Mineral Resources are inclusive of Mineral Reserves.
3. Open Pit Mineral Resources are reported at a cut-off grade of 0.45 g/t gold that is based on a gold price of C$2,000/oz (~US$1,600/oz) and a metallurgical recovery factor of 89% around cut-off as calculated from ((GRADE-(0.0262*LN(GRADE)+0.0712))/GRADE*100)-0.083.
4. Underground Mineral Resource is reported at a cut-off grade of 2.60 g/t gold that is based on a gold price of C$2,000/oz (~US$1,600/oz) and a gold processing recovery factor of 97%.
5. Assays were variably capped on a wireframe-by-wireframe basis.
6. Specific gravity was applied using weighted averages to each individual wireframe.
7. Effective date of the Mineral Resource Estimate is November 15, 2021.
8. All figures are rounded to reflect the relative accuracy of the estimates and totals may not add correctly.
9. Excludes unclassified mineralization located within mined out areas.
10. Reported from within a mineralization envelope accounting for mineral continuity.

All samples and the resultant composites referred to in this release are collected using QA/QC protocols including the regular insertion of standards and blanks within the sample batch for analysis and check assays of select samples. All samples quoted in this release were analyzed at Eastern Analytical Ltd. in Springdale, NL, for Au by fire assay (30 g) with an AA finish.

All assays in this press release are reported as fire assays only. For samples analyzing greater than 0.5 g/t Au via 30 g fire assay, these samples will be re-analyzed at Eastern Analytical Ltd. via total pulp metallics. For the total pulp metallics analysis, the entire sample is crushed to -10mesh and pulverized to 95% -150mesh. The total sample is then weighed and screened to 150mesh. The +150mesh fraction is fire assayed for Au, and a 30 g subsample of the -150mesh fraction analyzed via fire assay. A weighted average gold grade is calculated for the final reportable gold grade. Total pulp metallics assays for drillholes sited within this press release may be updated in a future news release.
