TDG relogged, resampled and assayed 26 diamond drillholes, totalling 2,900m of core, dating from 2007 and 2010, all drilled within the footprint of the existing Shasta Mineral Resource Estimate ('MRE1'). No historical assay results for the 2007 series drillholes were available and no collar locations for the 2010 series drillholes were previously verified. The collar locations have now been verified and the new assay data supports inclusion of these higher grade, near surface intercepts in a future MRE1.
Highlights include gold ('Au') and 57 g/t silver ('Ag') [1.75 g/t gold equivalent ('AuEq'2)] from 3.0 m depth and ending in mineralization, Including 43.1 m grading 1.27 g/t Au and 67 g/t Ag [2.11 g/t AuEq2] from 20.0 m depth SH07-04: 65.0 m grading 0.64 g/t Au and 18 g/t Ag [0.87 g/t AuEq2] from 78.0 m depth
Including 25.7 m grading 1.52 g/t Au and 40 g/t Ag [2.02 g/t AuEq2] from 78.0 m depth
SH07-10: : 53.0 m grading 1.08 g/t Au and 33 g/t Ag [1.49 g/t AuEq2] from 66.0 m depth
Including 25.3 m grading 1.93 g/t Au and 62 g/t Ag [2.71 g/t AuEq2] from 72.0 m depth
SH07-14: : 63.7 m grading 0.87 g/t Au and 42 g/t Ag [1.40 g/t AuEq2] from 43.8 m depth
Including 28.5 m grading 1.56 g/t Au and 86 g/t Ag [2.63 g/t AuEq2] from 45.5 m depth
2007 Series Drilling
The 2007 diamond drilling was mostly located along the western side of the Shasta deposit, in the Shasta zone. Historically, core was cut and sent for analysis, but the legacy data (assays and drill logs) were never located by TDG. TDG has now successfully located and validated the 2007 series drill collars and subsequently relogged, resampled and sent all recoverable drillcore for analysis of the precious metal content and a full suite of multi-element geochemistry. These drillholes add additional multi-element data TDG's existing database, and the precious metal assay results may positively impact the current Shasta MRE1 by improving confidence between existing drillholes and adding higher grades in areas with sparse drilling.
2010 Series Drilling
The 2010 series of diamond drilling was focused within the Cayley-Rainer zone. This zone has demonstrated potential to host bonanza grades, with SH21-022 intersecting 1.5 m grading 50.2 g/t Au and 4,871 g/t Ag [111 g/t AuEq1] from 113.5 m depth . Previously, the 2010 series drilling also suffered from poor collar validation and only two drillholes were sufficiently accurately recorded to support inclusion within the 2023 MRE1 calculation. As with the 2007 drillholes, the remaining 2010 drill collars have since been validated, and therefore this data may now be used in a potential MRE1 update. Additionally, these new assays and geochemical data could provide clues on vectoring between the Cayley-Rainer zone and the JM zone (400 m distance). This is an area where drill and historical assay density is currently the lowest at Shasta and the new information could potentially expand the bonanza grade mineralization intercepted in 2021.
1980s Series Drilling
In 2023, TDG also undertook a broader relogging, resampling and assaying program to target (a) the satellite deposits within the Greater Shasta target area and (b) potential extensions to the mineralization at the Shasta deposit. The drillcore from the Cody Lee target area5 and the Fisher target area5 were recovered and cores from 7 and 6 holes, respectively, were relogged, resampled and assayed in entirety; results are pending. Around the main Shasta deposit, drillcore with the potential to assist in upgrading the MRE1 and provide valuable multi-element data were also relogged and resampled from the JM east, Shasta north and
QA/QC
Samples for the Shasta 2023 relogging, resampling and assay program were handled via rigorous chain of custody, through sample collection, processing, and delivery to the ALS Global laboratory in either
QAQC is maintained internally at the lab through rigorous use of internal certified reference materials ('CRMs'), blanks, and duplicates. An additional QAQC program was administered by TDG through the verification of lab results via use of CRMs and blank (unmineralized) samples that were blindly inserted into the sample batch. Duplicates (pulp) were selected approximately every 20 samples by internal lab procedures. If a QAQC sample returns an unacceptable value an investigation into the results is triggered and when deemed necessary, the samples that were tested in the batch with the failed QAQC sample are re-tested.

Forward Looking Statements
This news release contains forward-looking statements that are based on the Company's current expectations and estimates. Forward-looking statements are frequently characterized by words such as, 'demonstrate', 'potential', 'validate', 'expand', 'yield', support', 'meaningful', 'extrapolate', 'impact', 'expand', 'valuable', and variations of these words as well as other similar words or statements that certain events or conditions 'could', 'may', 'should', 'would' or 'will' occur. Such forward-looking statements involve known and unknown risks, uncertainties and other factors that could cause actual events or results to differ materially from estimated or anticipated events or results implied or expressed in such forward-looking statements. Such factors include, among others: the actual results of current and planned exploration activities including the potential for positive changes to the current mineral resource estimate, expansion of higher grade zones and vectors for future exploration targeting; outcomes of future economic evaluations; changes in project parameters as plans to continue to be refined; possible variations in grades of mineralization and/or future actual recovery rates; accidents, labour disputes and other risks common to the mining industry; the availability of sufficient funding on terms acceptable to the Company to complete the planned work programs; delays in obtaining governmental approvals or financing and fluctuations in metal prices. There may be other factors that cause actions, events or results not to be as anticipated, estimated, or intended.
