QUESTEX GOLD & COPPER SAMPLES 22 GRAMS PER TONNE GOLD AND >100 GRAMS PER TONNE SILVER FROM OUTCROP ON ITS CASTLE PROPERTY, ADJACENT TO GT GOLD'S TATOGGA PROPERTY
Questex Gold & Copper Ltd. has released partial results from the 2020 exploration program that was conducted on its Castle property. Highlights include:
- 22 grab samples indicating widespread gold-silver-copper mineralization on the eastern portion of the Castle property, near GT Gold Corp.'s Tatogga property:
- Four grab samples collected over 28 metres from two parallel mineralized porphyritic dikes returned an average of 7.46 grams per tonne gold, greater than 62.6 g/t silver (overlimit analyses for two samples over 100 g/t Ag are pending) and 0.29 p[er cent copper, including one sample with 22.2 g/t Au, greater than 100 g/t Ag and 0.16 per cent Cu;
- Six of 11 grab samples collected from the Tuk showing, which is hosted in a monzonite intrusion along the Castle-Saddle trend, yielded significant results with up to 0.43 g/t Au, greater than 100 g/t Ag and greater than 1 per cent Cu.
- A new 4.8-line-kilometre induced polarization (IP) survey and a 3-D IP (induced polarization) inversion that incorporates the new, and all historical IP surveys. The new IP data:
- Indicate untested geophysical targets along strike of and beneath shallow drill holes at Castle Main and Castle East;
- Confirmed a parallel two km long trend of strong chargeability, which persists to greater than 300 m depth at Castle South, including an extension that indicates the anomaly may continue at least 1.25 km eastward. This 3.25 km long highly prospective trend has never been drilled.
Dr. Tony Barresi, president of Questex, commented: "New geophysical and gold-rich geochemical data from Questex's Castle property highlight compelling drill targets along the Castle-Saddle trend, and near the boundary with GT Gold's Tatogga property. Our new 3-D geophysical inversion indicates that chargeability anomalies, which define mineralization at Castle Main and Castle East, are persistent in both intensity and volume at depth in both areas, defining undrilled targets beneath and along strike of known porphyry-style mineralization that has been intersected in shallow drill holes. In a district where deep drilling has led to definition of high-grade resources at Saddle North and Red Chris, these geophysical data provide new evidence for what we consider must-drill targets along strike of GT Gold's Saddle North deposit."

Geochemical results
Twenty-two grab samples and 211 soil samples were collected from the Castle property during the 2020 field campaign. Results for all 211 soil samples and for overlimit copper and silver analyses from the grab samples are pending.
Four mineralized samples were collected from two parallel quartz-sericite-pyrite-altered porphyry dikes, which were observed and sampled over approximately 28 m strike length. These samples yielded 22.2, 5.5, 2.0 and 0.19 g/t Au, greater than 100, 12.3, 38.3 and greater than 100 g/t Ag, variable associated base metals, and elevated arsenic, bismuth, antimony and molybdenum. They were collected 150 m upslope of a 2019 float sample that yielded 11.9 g/t Au and greater than 100 g/t Ag. The metal tenor, epithermal-tracer-element association and geological setting of these samples are analogous to GT Gold's nearby Saddle South epithermal-gold-silver system located less than two km to the northeast.
A further six mineralized samples were collected near the Tuk showing, over a 250 m transect across a monzonitic stock along the Castle-Saddle trend, 1.6 km west of the claim boundary with GT Gold's Tatogga property. These samples contain between 0.23 and greater than 1 per cent Cu, as well as anomalous gold, up to 0.4 g/t, and silver greater than 100 g/t. The metal tenor of these samples indicates significant mineral potential along this portion of the Castle-Saddle trend.
Geophysical results
The 2020 field campaign at Castle included successful completion of a 4.8 line km IP survey over rugged ground near the eastern claim boundary with GT Gold's Tatogga property. The new IP data were combined in an inversion with 66 line km from previous IP surveys to generate 3-D chargeability and resistivity models that cover approximately 15 square km.
The new 3-D models reinforce Questex's exploration hypothesis that mineralization at Castle Main and Castle East extends to depth. In a few key locations, for example on the western side of Castle Main, some of the largest and most intense chargeability anomalies remain entirely untested by drilling.
Modelling also confirms a strong buried chargeable body that parallels the Castle-Saddle trend one km to the south (Castle South). The three new IP lines east of the Castle South anomaly define what may be an eastward extension; lines 101 and 501 detected increased chargeability on the southern extent of the survey, and line 701 identified a chargeability anomaly along trend to the east-southeast of Castle South. The intervening area is topographically unsuitable for IP surveys and therefore the continuity of the anomaly between Castle South and the eastern anomaly can only be hypothesized. Combined, Castle South and the eastern anomaly form a 3.25 km long trend of highly prospective geophysical anomalies that are mainly underlain by a thrust panel of Triassic sedimentary rock. The persistence of the anomaly to depth indicates that its source may lie beneath, and be disguised by, the thrust panel. The Castle South trend has not been tested by drilling.
Dave Fleming, Questex's vice-president, exploration, commented: "Questex's 2020 exploration program at Castle focused on the little-explored rugged eastern portion of the property, near the claim boundary with GT Gold's Tatogga property. Despite difficult weather conditions and severe topography, our crew was able to complete several important surveys that increase the prospectivity of this portion of the property for related epithermal and porphyry systems. The persistence of the Castle South IP anomaly to depth, and its newly demonstrated eastern extension, present a compelling, undrilled, porphyry target in the footwall of a thrust panel. The high-grade gold samples collected from altered porphyry dikes, just to the northeast of the newly defined IP anomaly, are consistent with a high-level epithermal expression in a porphyry to epithermal hydrothermal system model."

Quality assurance/quality control
Surface samples for the Castle 2020 exploration program followed chain of custody between collection and delivery to a Bureau Veritas (BV) laboratory in Vancouver, B.C. The samples were packed in polyurethane bags and then in security-sealed rice bags before being shipped directly from Northern British Columbia to the laboratory via Bandstra Transportation Systems. Samples were prepared for analysis according to BV method PRP80-250: Each sample was crushed to 85 per cent passing two millimetres and a 250-gram split was pulverized to 75 microns. Gold was tested by fire assay with atomic absorption finish on a 30-gram nominal sample (method FA430); samples that tested over 10 g/t Au were retested using a 30-gram sample with gravimetric finish (method FA530). An additional 36 elements were tested by ICP-ES/MS (inductively coupled plasma emission spectroscopy/mass spectrometry) using an aqua regia digestion (method AQ202). Quality assurance and quality control (QA/QC) are maintained at the lab through rigorous use of internal standards, blanks and duplicates. An additional QA/QC program was administered by Questex through the use of duplicate analyses and certified reference standards that were blindly inserted into the sample batch. QA/QC samples that return unacceptable values trigger investigations into the results and reanalysis of the samples that were tested in the batch with the failed QA/QC sample.
