Vancouver, British Columbia, August 31st, 2020 – Sentinel Resources Corp. (CSE: SNL)(US OTC PINK: SNLRF) (“Sentinel” or the “Company”) is pleased to provide an update on its summer exploration program for its 100%-owned Pass Property in the Nelson mining division of southeastern British Columbia.
Sentinel’s work program involved detailed geological mapping, soil and rock sampling. Sentinel field crew also ran 4.4 line kilometers of soil lines to collect soil samples as confirmation samples over locations of gold soil anomalies discovered by Swift Resources in 2011, and to follow up copper/gold soil anomalies discovered during the 2017 exploration work on the property by the previous option holder. A total of 229 soils and 9 rock samples were collected.
Several soil samples returned elevated values for gold in areas noted in the 2011 work as containing elevated gold soil values. Sentinel geologists considered gold soil values that were between 4 – 10 times greater than background values as being anomalous. Table 1 below contains highlights of the Soil sampling results.
Table 1. Soil analyses highlights of confirmation samples in previously samples areas
| SAMPLE | Au | Ag | Cu | Pb | Zn |
| ppm | ppm | ppm | ppm | ppm | |
| B846083 | 0.046 | 0.11 | 20.9 | 15.5 | 131 |
| B846067 | 0.02 | 0.4 | 44.6 | 23.7 | 82 |
| B846068 | 0.019 | 0.17 | 26.3 | 28 | 83 |
Sample B846083 was collected adjacent to an area that was test pitted by Swift Resources in 2011. The location test pitted at that timewas at the edge of clear cut and therefore the soil profile was likely disturbed by logging activities before they collected the soil sample. Sentinel crew made efforts to collect soil samples slightly upslope from the test pitted area and in undisturbed original forest cover. Sample B846083 confirms the presence of elevated soil gold values in that area.
Samples B846067 and B846068 were collected in an area identified by Swift Resources as having elevated soil Au values. The area had been recently clear cut however, Sentinel Resources was able to confirm the presence of elevated Au soil values in that area. The resampling effort supports Sentinel geologists belief that soil gold anomalies are likely the result of a bedrock gold source.
Soil lines were also run over newly discovered showings south of Granite Creek in an area previously unexplored by Sentinel crew or by previous operators. Several samples had elevated gold levels compared to background levels recorded in adjacent samples. Notably, sample B846105 which was collected in an area of forest cover, analyzed at approximately 10 times background. Samples B846552 and B846553 had elevated gold levels compared to surrounding soil samples. Table 2 presents highlights of the analysis of the above noted samples.
Table 2. Soil analyses highlights from south of Granite Creek.
| SAMPLE | Au | Ag | Cu | Pb | Zn |
| ppm | ppm | ppm | ppm | ppm | |
| B846105 | 0.038 | 0.14 | 27.3 | 15.4 | 37 |
| B846552 | 0.026 | 2.02 | 23.6 | 21.4 | 55 |
| B846553 | 0.015 | 0.12 | 87.1 | 15.4 | 86 |
Sentinel geologists are encouraged by the above noted results and believe trenching in locations with anomalously high soil gold values is warranted to locate the bedrock source of the goldsoil anomalies.
Bedrock exposed by road cuts and hereto unknown outcrops were mapped in detail. Results of the field work were encouraging in that previously unknown areas of gold mineralization were discovered south of Granite Creek in a newly logged cut block.
Rock sample B846531 returned 2.31g/t Au and 14.9g/t Ag. B846531 was collected from a massive sulphide vein exposed by a new road cut south of Granite Creek. Approximately 100m north-north west of the sulphide vein, Sentinel geologists mapped a silicified collapse breccia and collected rock sample B846530 that returned 0.14 g/t Au. The presence and relative positioning of the sulphide vein and the collapse breccia are considered by Sentinel geologists to be indicators of a mineralized system at depth. Table 3 below lists the highlights of rock sample analytical results.
Table 3. Selected Rock sample analytical results
| Sample | Au | Ag | Cu | Pb | Zn |
| ppm | ppm | ppm | ppm | ppm | |
| B846531 | 2.31 | 14.9 | 309 | 549 | 227 |
| B846530 | 0.14 | 0.1 | 58.6 | 2.5 | 39 |
The Company is encouraged by these results and intends to conduct additional groundwork in the area south of Granite Creek to further delineate the extent of the mineralized zone with the goal of ultimately defining targets for exploratory drill sampling.
QA/QC
Analytical results of soil and rock analyses reported by Sentinel Resources represent samples collected and submitted by Sentinel Resources staff directly to ALS Global – Geochemistry Analytical Lab in North Vancouver, BC, Canada.
Soil samples were logged into the ALS Lab sample tracking system using sample tag bar codes then weighed as per ALS method WEI-21, then screened to 180μm as per ALS method SCR-41 and analyzed for Trace Au + Multi Element package as per ALS method AuME-TL43. ALS provided analytical standards and blanks and performed duplicate analyses at regular intervals.
Rock samples were received, weighed, crushed, and split as per ALS Labs methods LOG-21, WEI-21, CRU-QC, CRU-31, SPL-21. Samples were then pulverized using method PUL-QC and PUL-31 to up to 250g with 85% < 75μm. Rock samples were then analyzed for Trace Au + multi element package AuME-TL43 and also Au FA ICP-AES Finish with ALS method Au-ICP21. The ALS – Global, Vancouver Geochemistry facilities are ISO/IEC 17025:2005 accredited. Laboratory control samples comprising certified reference samples, duplicates and blank samples were inserted by the laboratory into the sample stream and analyzed as part of the quality assurance/quality control protocol.
