More High-Grade Gold Results from Tempus' Elizabeth Project
August 16, 2021
PERTH, AUSTRALIA / ACCESSWIRE / August 16, 2021 / Tempus Resources Ltd (" Tempus " or the " Company ") (ASX:TMR)(TSX.V:TMRR)(OTCQB:TMRFF) is pleased to announce assay results from the three remaining diamond drill-holes (EZ-21-01, EZ-21-02 and EZ-21-03) from the assay batch submitted to the SGS Canada Inc. lab in June, incorporating the first four holes drilled in the 2021 drilling program at Elizabeth Gold Project in Southern BC, Canada. Assays from the other hole of the batch, EZ-21-04 were reported on 10 August, including ‘bonanza' grades.
HIGHLIGHTS
Second batch of assay results (holes EZ-21-01, EZ-21-02 and EZ-21-03) from ongoing 2021 drilling at Elizabeth return more high-grade gold results, including ‘bonanza' grade sub-section
Significant mineralised intersections include:
EZ-21-02 - 6.60m at 8.40g/t gold from 102.40m, including;
1.10m at 46.3g/t gold at 105.40m
EZ-21-03 - 6.40m at 7.22g/t gold from 88.60m, including;
1.30m at 19.8g/t gold from 90.00m, and;
0.50m at 3.15g/t gold at from 34.70m
EZ-21-01 - 1.80m at 6.37g/t gold from 94.80m, including;
0.50m at 20.5g/t gold from 83.5m
15 drill-holes completed so far at Elizabeth with multiple assays pending:
Assays for first four holes (including the three being reported today) are reported
Another ten holes are at the lab - four sent in July and six sent in last week
15 th hole being logged and samples prepared for despatch to the lab in a subsequent sample batch
Diamond drilling continues to demonstrate the SW Vein extends down dip and along strike - all extensional holes drilled appear to intersect quartz vein
Tempus President and CEO, Jason Bahnsen, commented "Exploration drilling at Elizabeth is generating outstanding results. Out of the 15 drill-holes completed in 2021 to date, all have hit vein structures with intersections ranging from half a metre to over six metres in thickness, including all down-plunge and strike extensional holes. Assays for the first four holes are showing high grades of up to 70g/t gold and excellent continuity to the vein structure at depth and along strike in both directions. With these results, Tempus is on-track to prepare a ‘maiden' modern NI43-101/JORC Mineral Resource estimate for the Elizabeth by year end."
The first four holes drilled by Tempus in 2021 including the three being reported today were aimed to demonstrate grade and width continuity within the relatively shallow upper part of the northern ore-shoot of the SW Vein. Those holes were hugely successful. The three being reported today all report high-grade significant intersections, with one of the holes also including a ‘bonanza' grade sub-section.
Significant mineralised intersections from the three drill-holes being reported in this announcement include:
EZ-21-02 - 6.60m at 8.40g/t gold from 102.40m, including;
1.10m at 46.3g/t gold at 105.40m
EZ-21-03 - 6.40m at 7.22g/t gold from 88.60m, including;
1.30m at 19.8g/t gold from 90.00m, and;
0.50m at 3.15g/t gold at from 34.70m
EZ-21-01 - 1.80m at 6.37g/t gold from 94.80m, including;
0.50m at 20.5g/t gold from 83.5m
Assays from the other hole of the first batch of four drill-holes, hole EZ-21-04, were received earlier and reported by the Company on 10 August, returning 4.00m at 31.2g/t gold including 1.50m at 52.1g/t gold and 0.50m at 72.0g/t gold ( see Tempus' ASX release of 10 August 2021 and Appendix 1 for details ).
Current exploration drilling for the Elizabeth Gold Project is largely focused the SW Vein, which hosted approximately 70% of the historic inferred resource of 206,139 ounces of gold (522,843 tonnes at 12.26g/t gold - SRK 2009). The holes drilled to date have been designed to address two aims: (i) confirm and upgrade the geological confidence of zones included in the historical resource; and (ii) extend the known mineralisation along strike and down plunge. The first batch of four 2021 holes address the first aim well. However, the majority of 2020-2021 drill holes address the second aim.
To date, Tempus has completed approximately 6,000 metres of new drilling at Elizabeth (of the total announced Phase 1 program of 12,000 metres) since the program started in November 2020, including 15 drill-holes completed for approximately 4,000 metres since the program re-commenced in early-June 2021.
The current status of the 15 completed drill-holes in 2021 is that four have now been reported (including three in this release), two additional batches combining 10 holes are at the lab (four sent in July and six last week) and the 15 th hole is currently being logged with samples to be included in a subsequent batch for the lab.
Recently completed drill-holes EZ-21-05, EZ-21-06, EZ-21-07, EZ-21-09, EZ-21-10, EZ-21-11, EZ-21-12, EZ-21-14; and EZ-21-15 were planned to extend mineralisation beyond the zone covered by the historic resource down plunge and along strike. Where drilling is planned at approximately 50-metre centers along strike, and below the northern and southern mineralised chutes. The program will also include a series of upcoming holes that step down plunge another 50 metres. Importantly, every one of these drill-holes has so far intersected the SW Vein structure, with quartz vein intersections ranging from half a metre up to four metres . Tempus' exploration team is impressed with the consistency shown by this.
Given the apparent success of the Phase 1 program to date at Elizabeth and the exciting results from the recent tenement-wide geophysical surveys ( see Tempus' ASX release of 2 August 2021 ), Tempus has appointed respected Canadian mining contractor and EPCM company, JDS Energy & Mining Inc. (" JDS ") to assist prepare a plan to re-open the Lower Portal at Elizabeth (see Figure 3 below), extend the existing drift by approximately 100 metres and then add an approximately 300 metre cross-cut drift at the end, running parallel to the SW Vein to facilitate drilling from underground. Once complete, the plan will be submitted to regulators for their approval. Drilling from underground will increase efficiency of drilling the down-plunge extension of the SW Vein but also greatly ease winter drilling plans.
The Elizabeth Gold Project is the flagship project for Tempus and is located in the Bralorne - Pioneer Gold District of southern British Columbia. The 115km 2 project is a relatively underexplored high-grade mesothermal gold project with mineralisation presenting itself in vein sets which range in true width from 1 m to 6.5 metres. The high-grade quartz veins encountered in the drilling at Elizabeth show close geological similarities to the Bralorne-Pioneer mesothermal vein system (approximately 30km away), which was mined to a depth of approximately 2,000 metres and produced more than 4 million ounces of gold over a period of more than 70 years (from approximately 1900 to 1971).

Criteria
JORC Code explanation
Commentary
Drill sample recovery
Method of recording and assessing core and chip sample recoveries and results assessed.
Measures taken to maximise sample recovery and ensure representative nature of the samples.
Whether a relationship exists between sample recovery and grade and whether sample bias may
have occurred due to preferential loss/gain of fine/coarse material.
Detailed calculation of recovery was recorded, with most holes achieving over95%
No relationship has yet been noted between recovery and grade and no sample bias was noted to have occurred.
Logging
Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.
The total length and percentage of the relevant intersections logged.
Detailed geological and geotechnical logging was completed for each hole.
All core has been photographed.
Complete holes were logged.
Sub- sampling techniques and sample preparation
If core, whether cut or sawn and whether quarter, half or all core taken.
If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.
For all sample types, the nature, quality and appropriateness of the sample preparation technique.
Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples.
Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.
Whether sample sizes are appropriate to the grain size of the material being sampled.
Half core was sampled, using a core saw.
Duplicate samples of new and historical core are Quarter core or half core where not previously sampled
Sample sizes are considered appropriate for the grain size of the material being sampled.
It is expected that bulk sampling will be utilised as the project advances, to more accurately determine grade.
Quality of assay data and laboratory tests
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.
Nature of quality control procedures adopted (eg standards, blanks,duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.
Core samples that have been sent to the lab for analysis include control samples(standards, blanks and prep duplicates) inserted at a minimum rate of 1:5 samples.
In addition to the minimum rate of inserted control samples, a standard or a blank is inserted following a zone of mineralization or visible gold
Further duplicate samples were analysed to assess variability
Verification of sampling and assaying
The verification of significant intersections by either independent or alternative company personnel.
The use of twinned holes.
Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
Discuss any adjustment to assay data.
Re-assaying of selected intervals of historic core have been sent for analysis.
Location of data points
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
Specification of the grid system used.
Quality and adequacy of topographic control.
All sampling points were surveyed using a hand held GPS.
UTM grid NAD83 Zone 10.
A more accurate survey pickup will be completed at the end of the program, to ensure data is appropriate for geological modelling and Resource Estimation.
Down hole surveys have been completed on all holes.
Data spacing and distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
Most drilling is targeting verification and extension of known mineralisation.
It is expected that the data will be utilised in a preparation of a Mineral Resource statement.
Additional drilling is exploration beneath geochemical anomalies, and would require further delineation drilling to be incorporated in a Mineral Resource.
Orientation of data in relation to geological structure
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
In general, the aim was to drill perpendicular to the mineralised structures, to gain an estimate of the true thickness of the mineralised structures.
At several locations, a series (fan) of holes was drilled to help confirm the orientation of the mineralised structures and to keep land disturbance to a minimum.
Sample security
The measures taken to ensure sample security.
Samples from Elizabeth were delivered to the laboratory by a commercial transport service.
Audits or reviews
The results of any audits or reviews of sampling techniques and data.
An independent geological consultant has recently visited the site as part of preparing an updated NI43-101Technical Report for the Project.

There are currently no known impediments to developing a project in this area, and all tenure is in good standing.
Exploration done by other parties
Acknowledgment and appraisal of exploration by other parties.
In the 1940s, placer gold was discovered in Fairless Creek west of Blackdome Summit.Prospecting by Lawrence Frenier shortly afterward led to the discovery of gold-bearing quartz veins on the southwest slope of the mountain that resulted in the staking of mining claims in 1947. Empire Valley Gold Mines Ltd and Silver Standard Resources drove two adits and completed basic surface work during the 1950s.
The Blackdome area was not worked again until 1977 when Barrier Reef Resources Ltd. re-staked the area and performed surface work in addition to underground development. The Blackdome Mining Corp. was formed in 1978 and performed extensive surface and underground work with various joint venture partners that resulted in a positive feasibility study. A 200 ton/day mill, camp facilities and tailings pond were constructed and mining operations officially commenced in 1986. The mine ceased operations in 1991,having produced 225,000oz of Au and 547,000oz of Ag from 338,000tons of ore (Godard et al., 2010)
After a period of inactivity, Claimstaker Resources Ltd. took over the project, reopening the mine in late 1998.
Mining operations lasted six months and ended in May of 1999. During this period, 6,547 oz of Au and 17,300 oz of Ag were produced from 21,268 tons of ore. Further exploration programs were continued by Claimstaker over the following years and a Japanese joint venture partner was brought onboard that prompted a name change to J-Pacific Gold Inc. This partnership was terminated by 2010, resulting in another name change to Sona Resources Corp.
Gold-bearing quartz veins were discovered near Blue Creek in 1934, and in 1940-1941 the Elizabeth No. 1-4 claims were staked.
Bralorne Mines Ltd. optioned the property in 1941 and during the period 1948-1949, explored the presently-named Main and West Veins by about 700 metres of cross-cutting and drifting, as well as about 110 metres of raises.
After acquiring the Elizabeth Gold Project in 2002, J- Pacific (now Sona) has conducted a series of exploration programs that included diamond drilling 66 holes totalling8962.8 metres (up until 2009) Other exploration work by Sona at the Elizabeth Gold Project has included two soil grid, stream sediment sampling, geological mapping and sampling,underground rehabilitation, structural mapping and airborne photography and topographic base map generation.
Geology
Deposit type, geological setting and style of mineralisation.
The Blackdome property is situated in a region underlain by rocks of Triassic to Tertiary age. Sedimentary and igneous rocks of the Triassic Pavilion Group occurring along the Fraser River represent the oldest rocks in the region. A large, Triassic age, ultramafic complex (Shulaps Complex)was emplaced along the Yalakom fault; a regional scale structure located some 30 kilometres south of the property. Sediments and volcanics of the Cretaceous Jackass Mountain Group and Spences Bridge/Kingsvale Formations overlie the Triassic assemblages. Some of these rocks occur several kilometres south of Blackdome.
Overlying the Cretaceous rocks are volcanics and minor sediments of Eocene age. These rocks underlie much of Blackdome and are correlated with the Kamloops Group seen in the Ashcroft and Nicola regions. Geochemical studies (Vivian, 1988) have shown these rocks to be derived from a "calc-alkaline" magma in a volcanic arc type tectonic setting. Eocene age granitic intrusions at Poison Mountain some 22 kilometres southwest of Blackdome are host to a gold bearing porphyry copper/molybdenum deposit.It is speculated that this or related intrusions could reflect the source magmas of the volcanic rocks seen at Blackdome. There is some documented evidence of young granitic rocks several kilometres south of the mine near Lone Cabin Creek. The youngest rocks present are Oligocene to Miocene basalts of the Chilcotin Group. These are exposed on the uppermost slopes of Blackdome Mountain and Red Mountain to the south.
Transecting the property in a NE-SW strike direction are a series of faults that range from vertical to moderately westerly dipping. These faults are the principal host structures for Au- Ag mineralisation. The faults anastomose, and form sygmoidal loops.
The area in which the Elizabeth Gold Project is situated is underlain by Late Paleozoic to Mesozoic rock assemblages that are juxtaposed across a complex system of faults mainly of Cretaceous and Tertiary age. These Paleozoic to Mesozoic-age rocks are intruded by Cretaceous and Tertiary-age stocks and dykes of mainly felsic to intermediate composition, and are locally overlain by Paleogene volcanic and sedimentary rocks. The Elizabeth Gold Project is partly underlain by ultramafic rocks of the Shulaps Ultramafic Complex, which include harzburgite, serpentinite and their alteration product listwanite.
The gold mineralisation found on the Elizabeth Gold Project present characteristics typical of epigenetic mesothermal gold deposits.The auriferous quartz vein mineralisation is analogous to that found in the Bralorne- Pioneerdeposits. Gold mineralisation is hosted by a series of northeast trending, steeply northwest dipping veins that crosscut the Blue Creek porphyry intrusion. The Main and West vein systems display mesothermal textures,including ribboned-laminated veins and comprehensive wall rock breccias. Vein formation and gold mineralisation were associated with extensional- brittle faulting believed to be contemporaneous with mid- Eocene extensional faulting along the Marshall Creek, Mission Ridge and Quartz Mountain faults.
Drill hole Information
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
easting and northing of the drill hole collar
elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar
dip and azimuth of the hole
down hole length and interception depth
hole length.
If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.
Refer to Appendix 1 for drillhole collar information
Data aggregation methods
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades)and cut-off grades are usually Material and should be stated.
Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results,the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
The assumptions used for any reporting of metal equivalent values should be clearly stated.
Intervals reported using several samples are calculated using a weighted average.
Calculated intervals using a weighted average did not use a top cut on high-grade samples.High-grade samples are reported as ‘including'
Calculated weighted average intervals are continuous intervals of a mineralized zone and do not include unsampled intervals or unmineralized intervals.
Relationship between mineralisation widths and intercept lengths
These relationships are particularly important in the reporting of Exploration Results.
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length,true width not known').
In general,drilling is designed to intersect the mineralized zone at a normal angle,but this is not always possible.
For the reported intervals, true widths are reported where mineralized core was intact and possible to measure the orientation. Otherwise the true width is left blank
Diagrams
Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.

Balanced reporting
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.
Where broader low-grade intervals are reported the high-grade intercepts are reported as ‘including' within the reported interval
Other substantive exploration data
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
Tempus recently completed an airborne magnetic and radiometric survey over the Elizabeth Gold Project (refer to ASX announcement 02 August 2021) by completing 97 lines for a total of 735 line-kilometres. Flight lines are oriented east-west with north-south tie lines and spaced 200 metres across the entire 115km2 Elizabeth property. Line spacing of 100 metres was flown over the Elizabeth Main and Elizabeth East Zones.
The airborne magnetic survey data was reviewed and interpreted by Insight Geophysics Inc. using 3D magnetization vector inversion (MVI) modelling.
The geophysical surveys identified the Blue Creek Porphyry, which is the known host of the high-grade Elizabeth gold-quartz veins, as a relative magnetic low anomaly within the Shulaps Ultramafic Complex. From this correlation of geology and geophysics it was determined that the Blue Creek Porphyry, originally explored / mapped to approximately 1.1km2 in size, is likely much larger. The airborne magnetic survey and MVI 3D modelling interpret the Blue Creek Porphyry to be at least four-times the size at approximately 4.5km2.
This interpretation of the Blue Creek Porphyry is also extensive at depth extending to at least 2km deep
Further work
The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large- scale step-out drilling).
Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
Tempus plans to update historical NI43-101foreign resource estimates to current NI43-101and JORC 2012 standards
Tempus is also seeking to expand the scale of the mineralisation at the project through further exploration.
