Treasury Metals Announces Exploration Program at Goldrock Property

Press Release

September 13, 2022


  •  Completion of prospecting program on Goldrock Property South of Dryden.
  •  Upcoming Airborne geophysical survey to be completed on property in the next month.


TORONTO, Sept. 13, 2022 – Treasury Metals Inc. (TSX: TML) (OTCQX: TSRMF) (“Treasury” or the “Company”) is pleased to announce the completion of a prospecting program at the 100% owned Goldrock Property (“Goldrock”) located approximately 30 km south of the city of Dryden in Northwestern Ontario, approximately 40 km southwest of the Company’s Goliath Gold Complex. The Company will follow up this prospecting campaign with an airborne geophysical survey starting late September.

Jeremy Wyeth, President and CEO of Treasury Metals, commented: “Our Exploration strategy for 2022 has been to assess our regional land package for further opportunities. These early-stage exploration campaigns, such as what we have just completed at Goldrock fit into that strategy well. The geological team has been working on a wholistic review of the area to better understand how the deposits were formed and where to find more of them. We are excited about the progress from the early-stage prospecting and look forward to the results from the geophysics work later this year for potential additional prospective targets.”

The Goldrock Property is located in the historic Goldrock Mining Camp which is hosted in the Eagle-Wabigoon-Manitou Lakes greenstone belt. The property covers the Manitou anticline which is a large-scale regional fold adjacent to the Manitou Straits Shear Zone (Figure 2). Regional folds often act as excellent traps for gold mineralization. Shear zones or faults act as fluid conduits for mineralizing fluids during the formation of gold deposits. The Manitou Straits Shear Zone is interpreted to be approximately 4-5 km wide composed of anastomosing discrete shear zones that trend northeast through the Goldrock Mining Camp. Mapping had shown additional shear zones running through the Goldrock Property. Several historic mines are located proximal to the regional shear zone structures and historic test pits and shafts are located throughout the area.

Treasury conducted prospecting and mapping at the Goldrock Property during the summer of 2022. Sixty-two samples were collected for geochemical analysis, all samples will be analyzed for gold and 4-acid near total digestion ICP, while representative (less altered and deformed) samples will undergo whole-rock geochemistry. The geochemical alterations will be compared to the Goliath and Goldlund deposits and other greenstone hosted gold deposits to look for path finder elements and trends.

The prospecting team encountered favourable mineralization and veining in outcrops at Goldrock. Historically, mineralization in the Goldrock camp has been associated with quartz-veining in mafic to intermediate volcanic rocks within the shear zone footprint. In addition, sheared and altered volcanic rocks with sulphide mineralization (predominantly pyrite) has been associated with gold mineralization. The Treasury team encountered several locations with volcanics hosting up to metre-wide quartz veining with abundant euhedral pyrite mineralization (Figure 3). The areas with the most extensive shearing also showed strong silicification alteration with sulphide mineralization.

The new mapping coupled with the detailed airborne geophysical survey will help to define the location and intensity of the anastomosing shear zones within the property. Historic mines have been located proximal to shear zones, therefore identification of the shear zones on the property will be a key exploration vector (Figure 2). The airborne geophysical survey planned for later this month will be helpful for defining these shear zones across the property where outcrops are not prevalent.

The Company will be flying an Airborne Geophysical program starting in late September which will include digital line profile data, electromagnetic and magnetic survey. Treasury will be running a NRGTM (New Resolution Geophysics) Xcite TDEM system, this provides a superior and efficient alternative to all prior HTDEM technologies for the mineral exploration community. The NRGTM has developed a proprietary algorithm which allows the magnetic sensor to be mounted on the EM transmitter loop. This configuration ensures the magnetic sensor is close to the geological source improving the source to noise ratio. The key for explorers being that there is an improved definition on geological anomalies. Following the geophysical survey, the Company will begin a regional geological interpretation for Goldrock which integrates the new datasets for exploration targeting.

The Company has implemented a quality assurance and quality control (QA/QC) program to ensure sampling and analysis of all exploration work is conducted in accordance with the CIM Exploration Best Practices Guidelines. The drill core is sawn in half with one-half of the core sample dispatched to Activation Laboratories Ltd. facility located in Dryden, Ontario. The other half of the core is retained for future assay verification and/or metallurgical testing. Other QA/QC procedures include the insertion of blanks and Canadian Reference Standards for every tenth sample in the sample stream. A quarter core duplicate is assayed every 20th sample. The laboratory has its own QA/QC protocols running standards and blanks with duplicate samples in each batch stream.  Additional checks are routinely run on anomalous values including gravimetric analysis and pulp metallic screen fire assays. Gold analysis is conducted by lead collection, fire assay with atomic absorption and/or gravimetric finish on a 50-gram sample. Check assays are conducted at a secondary ISO certified laboratory (in this case AGAT Laboratories located in Mississauga, Ontario) following the completion of a program.
