Tempus Announces High-Grade Assays Elizabeth Gold Project

Sampling techniques

• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.
• Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
• Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

• HQ (63.5 mm) sized diamond core using standard equipment.
• Mineralised and potentially mineralised zones, comprising veins, breccias, and alteration zones were sampled.
• Samples were half core.
• Typical core samples are 1m in length.
• Core samples sent to the lab will be crushed and pulverized to 85% passing 75 microns. A 50g pulp will be fire assayed for gold and multi-element ICP. Samples over 10 g/t gold will be reanalysed by fire assay with gravimetric finish

Drilling techniques

• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).

• Diamond Drilling from surface (HQ size)

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 over 95%
• No relationship has yet been noted between recovery and grade and no sample bias was noted to have occurred.

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 225,000 oz of Au and 547,000 oz of Ag from 338,000 tons 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 totalling 8962.8 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-Pioneer deposits. 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 drill hole 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.

• Refer to maps within announcement for drill hole locations.

Commentary

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.

• Not applicable.

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 NI43-101 foreign resource estimates to current NI43-101 and JORC 2012 standards
• Tempus is also seeking to expand the scale of the mineralisation at the project through further exploration.
