- Soil geochemistry sampling results reconfirm the presence of copper and gold mineralization at Valle del Tigre - highlighting two zones of anomalous copper and gold values within the 5 km2 survey area
- Copper-bearing minerals, chalcopyrite and bornite observed within the survey area, as well the presence of sericite and potassic alteration
- Anomalous copper and gold results correlate with 3 km geophysical anomaly "footprint" of target mineralisation zone identified in previous ZTEM fly over survey
Tempus Resources Ltd ("Tempus" or the "Company") (ASX:TMR, TSX.V:TMRR, OTCQB:TMRFF) is pleased to announce the results from the Phase 2 sampling program at the Valle del Tigre Project (VdT) located in south-eastern Ecuador. The Phase 2 program was a larger scale follow-up to the initial reconnaissance work conducted during February 2021 where areas with anomalous gold and copper were discovered (see Tempus announcement dated 25 March 2021
Results from the Phase 2 sampling program reconfirm the presence of gold and copper mineralization at Valle del Tigre and show a direct correlation with the geophysical anomalies generated by the airborne geophysical survey (ZTEM) work that Tempus conducted on the project in 2019.
Tempus President & CEO, Jason Bahnsen commented "The results of our Phase 2 exploration program at Valle del Tigre highlight the potential of the project for both copper and gold mineralisation. The MMI soil geochemistry results have identified two strongly anomalous areas within the overall 3km geophysical footprint that we will target for further exploration work. The Vdt project is centrally located in a major copper porphyry mineralisation trend that hosts several major copper deposits."
The Phase 2 exploration program included a Mobile Metals Ion (MMI) geochemistry soil sampling survey over an area of approximately 5 square kilometres in addition to rock and stream sediment samples. In total 505 MMI soil samples were collected, together with 53 rock samples and 48 stream sediment samples.
In 2019, Tempus conducted a ZTEM, Magnetics and Radiometrics helicopter-borne geophysical survey over the VdT license area (see Tempus announcement dated 15 December 2019). The airborne geophysics defined two east-west trending magnetic highs which are transected by a strong northeast trending ZTEM anomaly that extends for over 3 km in length. At other regional copper porphyry projects including, Panantza, Mirador and Warintza, the copper mineralization occurs in east trending zones with a similar orientation to the two magnetic anomalies that occur at VdT.
The Phase 2, MMI soil, rock and stream sediment sample results have identified two anomalous areas that display good coincidence for copper, gold, molybdenum and bismuth (see Figure 2 and Figure 3). Chalcopyrite and bornite plus sericite and potassic alteration was observed within the sample area.

Tempus is currently completing further analysis and review of the geochemical and geophysical results with regard to next steps towards refining target locations for a future drill program.
Valle del Tigre is centrally located in a newly emerging copper porphyry belt that includes the El Hito and Santa Barbara deposits to the south (Lumina Gold) and Mirador, Panantza and Warintza deposits to the northeast (Figure 1).
There are strong geological similarities between VdT and Warintza and Mirador with the Hollin Formation unconformably overlying the Misahualli Formation which is underlain by the older Zamora Batholith (see Figure 2). Copper mineralization in the northern part of the copper district is associated with a younger intrusive phase of the Zamora Batholith which has been dated as upper Jurassic in age.
All samples were collected by Tempus Resources under the supervision of Mr. Sonny Bernales (CPG, QP) who maintained chain of custody until delivery of the samples to SGS Laboratories in Lima, Peru for preparation and analysis. SGS's facility in Lima, Peru is accredited to the ISO 9001 standard for assays and all analytical methods include quality control materials at set frequencies with established data acceptance criteria.
The Phase 2 exploration program was conducted between 30 January 2022 to 23 February 2022. In total 505 MMI soil samples were collected, together with 53 rock samples and 48 stream sediment samples.
Mobile Metal Ion (MMI) Soil Samples
The MMI soil samples were collected on an approximate grid spacing of 200m by 50m (grid spacing irregular over some areas of extreme topography). In total 505 MMI soil samples were collected with duplicates added on a ratio of 1 duplicate for every 50 samples.
The VdT soil samples were analyzed by SGS Laboratories in Lima, Peru utilizing mobile metal ionic leach analysis for a 60-element suite. The key benefits to using partial ionic leach extraction for soil analysis compared to the industry standard aqua regia digestion includes the following:
- Fewer false anomalies are generated
- Anomaly better positioned directly above the mineralization
- Excellent element value repeatability at very low detection limits
- A better definition of metal zonation and complex metal associations
- More effective at detecting deeply buried mineralization
- Very low detection limits with low background noise
- Important pathfinder volatile elements are retained
A total of 53 rock samples were collected during the Phase 2 exploration program.
The rock samples were analysed using SGS's FAA313 method for gold, that is, samples were crushed, split and pulverized to -200 mesh. Analysis for gold was completed using a 30-gram fire assay fusion and flame atomic absorbtion (trace grade) with a lower limit of 5 parts per billion for gold and upper limit of 10000 ppb. Crushed and pulverized rock sample are weighed and mixed with flux and fused using lead oxide at 1100o C, followed by cupellation of resulting lead button (Dore bead). The bead is digested using 1:1 HNO3 and HCl and the resulting solution is submitted for analysis. The digested sample solution is analysed by Flame Atomic Absorbtion Spectrometer (AAS). Samples are analysed against known calibration material to provide quantitative analysis of the original sample.
For multi-elements, 49 elements, including copper, Ag, etc, the method used was SGS's ICP40B, by four-acid digestion / ICP-AES and ICP-MS.
Stream Sediment Samples
A total of 48 stream sediment samples were collected during the Phase 2 exploration program.
Same laboratory method as rock samples, that is, FAA313 for gold and ICP40B, by four-acid digestion / ICP-AES and ICP-MS for 49 multi-elements.
