Tertiary Minerals #TYM reports encouraging analytical results from the Lucky Copper Project
Tertiary Minerals plc is pleased to announce encouraging analytical results from its maiden drill hole at the Lucky Copper Project in Nevada, USA.
Highlights:
- Hole 21TLRC001 was drilled to a depth of 108.24m.
- Two magnetic gossan zones intersected containing low-grade copper (+/-gold) mineralisation:
- 57m grading 0.12% copper and 0.12 g/t gold from 15.24m down hole.
- 05m grading 0.40% copper from 33.53m down hole.
- Highly anomalous copper (average 325ppm copper) over 24.38m from 83.82m to the base of hole.
- Geological evaluation of drill samples ongoing.
- Follow up magnetic survey planned.
Commenting today, Executive Chairman Patrick Cheetham said:
“This maiden drill hole has confirmed the occurrence of copper mineralisation in magnetic gossan zones at shallow depth. The geological setting of the mineralisation is not yet defined but trace element geochemistry suggests the gossans are developed from skarn-style mineralisation, a class of deposit containing a number of large economic copper deposits in Nevada and the adjoining States. Detailed evaluation of the drill samples is underway to define the host rock stratigraphy and a magnetic survey is planned to define additional drill targets.”

Detailed information
The Lucky Copper Project was staked by the Company in 2020 and is located on the east side of the old Aurum mining centre, 96km northeast of the major porphyry copper mining town of Ely in north-east Nevada.
The project is targeting disseminated copper mineralisation first identified during exploration carried out in the 1950s.
The Company’s drill hole 21TLRC001 was drilled vertically using the reverse circulation percussion method and samples were collected at 5ft (1.52m) intervals down hole.
The holes passed through 6.1m of overburden and a mixed sequence of sedimentary rocks down to the end of the hole at 108.20m.
Two zones of gossan were intersected at 15.24m and 33.53m down hole as shown in the table below. In addition, a wide zone of anomalous copper was intersected from 83.82m to the base of hole at 108.20m. Extensive faulting was encountered from 38m down to the bottom of the hole. The strike and dip of the mineralisation intersected is not yet known.

Down Hole | From | to | |||
interval | From | to | Copper | Gold | Silver |
m | m | m | % | g/t | g/t |
4.57 | 15.24 | 19.81 | 0.12 | 0.12 | 3.23 |
3.05 | 33.53 | 36.58 | 0.40 | 0.00 | 8.75 |
24.38 | 83.82 | 108.20 | 0.03 | 0.00 | 0.91 |
Gossans are typically produced by surface and near surface weathering of metallic deposits and any contained copper sulphide minerals originally contained in such deposits are oxidised and the contained copper can be either leached out or enriched. Consequently, the grade of the mineralisation in gossans is not necessarily a reliable indicator of the grade of the mineralisation from which it is derived.
A nearby percussion hole drilled in 1951 was reported to have intersected a 20.4m cumulative thickness of mineralisation which assayed 0.65% copper to the bottom of the hole at 77.7m depth. That hole also ended in mineralisation .
These early drill results are considered to be encouraging. The gossan zones contain magnetic material which may be remnant magnetic sulphides such a pyrrhotite, or magnetic oxide minerals such as magnetite or maghemite, and it is likely that the original mineralisation will be magnetic and responsive to magnetic surveying. A drone magnetic survey is therefore planned to define additional drill targets.
A programme of petrological work is also planned to better define the host rock lithologies and the geological setting of this mineralisation and assist further exploration targeting.
Notes:
- All drill samples were submitted to Paragon Geochemical, Reno for sample preparation and analysis. Analysis was performed using method 34MA OES, a 34 element multi-acid ICP/OES and aqua regia ICP/MS package (Hg), and Au AA30, 30g fire assay with aqua regia digest and AAS finish. Quality control samples were inserted into the sample run by the Company and standards and blanks were run by the analytical laboratory for internal QA/QC purposes

Tertiary Minerals #TYM – Lucky Copper Project Drilling
Tertiary Minerals plc is pleased to advise that drilling is scheduled to start today on the Company’s Lucky Copper Project in Nevada, USA.
The target is a disseminated sediment hosted, intrusion-related copper deposit and details of the project and the planned drill hole can be found in the Company’s announcements of 29 May 2020 and 11 January 2021.
Results of the drilling will be advised once analytical results become available.
Commenting today, Executive Chairman Patrick Cheetham said:
“We have decided to drill at an early stage on this project as historical exploration results present an immediate target with reported copper mineralisation that needs to be confirmed and put into a better geological context. We look forward to reporting results as they become available.”

Tertiary Minerals #TYM – New Copper Exploration Project, Brunton Pass, Nevada, USA
Tertiary Minerals plc is pleased to announce that it has staked claims over a new copper exploration project at Brunton Pass in Nevada, USA.
Highlights
Brunton Pass Copper Project, Nevada (100% owned by Tertiary)
- 24 mining claims staked with copper mineralisation spread over a 1km x 0.6km target area.
- Samples collected by United States Bureau of Mines (USBM) contain up to 6.91% copper including a chip sample grading 1.36% copper over 3.66m (12ft).
- Follow up samples taken by the Company confirm widespread copper mineralisation and include an 8ft channel sample grading 4.66% copper over 2.44m (8ft) .
- Copper mineralised samples also anomalous in uranium – large scintillometer anomaly reported.
- Exploration underway, drone magnetic survey commissioned to commence within the next two weeks.
Commenting today, Executive Chairman Patrick Cheetham said:
“I am delighted to be announcing this new project acquisition as we continue to build our mineral project portfolio in Nevada. We have been able to confirm historic reports of widespread copper mineralisation with significant grades at surface.
This adds a second copper project alongside our precious metals projects and complements our Lucky Copper Project where our planned drill programme is now permitted and where we expect to be drilling as soon as a rig becomes available. Copper is increasingly a focus for the Company. It is a key metal in electric vehicles, prices are strong, and the market outlook is favourable.”
We look forward to reporting exploration results from this exciting prospect in what is shaping up to be a busy and a pivotal year for the Company.”

Brunton Pass Copper Project
The Company has staked 24 new mining claims on the east side of the Paradise Range, just north of State Highway 91, 190 km southwest of Reno, Nevada.
Mercury was discovered in the claim area in 1945 and a small amount of mercury was produced in 1948. The area south of the mercury workings was drilled by Phillips Uranium Corp. in 1978 to test a reportedly large scintillometer anomaly but no further records can be found.
In 1991 the area was mapped and sampled by the US Bureau of Mines (USBM) during a study of the mines, prospects, and mineral occurrences of that part of the Paradise Range, administered as Toiyabe National Forest, although the prospect is itself outside of the National Forest.
The prospect area is underlain by Triassic-age limestone, sandstone, and siltstone which has been intruded by diorite. The sedimentary rocks are strongly altered locally and appear to be in fault contact with Tertiary-age volcanic rock (rhyolite) on all sides. Prospector small-scale workings are spread throughout a 1km x 0.6km area within the sedimentary enclave. Most of the workings explore shear zones and contact metasomatic (skarn) zones containing garnet, epidote, calcite, and copper minerals. Zones of silicification are abundant.
The USBM collected a total of 14 samples from across the prospect area and 8 of these contained values above 1% copper and up to 6.91% copper including a chip sample over 12ft (3.66m) grading 1.36% copper.
In addition to the copper and mercury zones, the area contains anomalous gallium, bismuth, tellurium, selenium, thallium, and arsenic, all elements considered to be precious metal “pathfinder” elements.
Prior to staking its claims the Company carried out a reconnaissance of the southern half of the prospect to confirm the USBM records of widespread copper mineralisation.
Of 10 grab and chip samples taken by the Company 5 samples contained over 1% copper including an 8ft (2.44m) channel sample grading 4.66% copper.
Other samples were significantly anomalous including an outcropping jasperoid containing 0.31% copper.
The Company’s copper-rich samples are also anomalous in uranium (up to 106ppm) and so the report of a large scintillometer further enhances the prospectivity of the project.
The Company has commissioned a detailed drone magnetic survey to assist in target delineation. This will be carried out within the next two weeks and further exploration will follow.
A thematic plan illustrating the information contained in this news release will be available on the Brunton Pass Project specific page of the Company’s website.
