This Haib Copper Mineral Resource has been defined by diamond core drilling covering a total surface area of some 2.6 square kilometres. The mineral resource classification is closely related to data proximity. Topographic elevations within the mineral resource area vary from 320m to 640m above mean sea level and average 480m above mean sea level. Indicated resources are constrained between the variable topographic surface and a horizontal level which is 75m above mean sea level and within which the majority of the drill and assay data are constrained. Inferred resources are laterally constrained by the last line of drill holes and extend vertically from the horizontal surfaces defined by the +75m and -350m above mean sea level ( a block of 425m thickness) within which there is a lesser data set derived from drilling.
Mineralization is open near surface and at depth to at least 800 metres deep. The Mineral Resource estimate is based on the results from approximately 66,500 metres of drilling in 196 holes. The most recent drilling data comes from Teck Resources drilling programs totalling 14,500 metres (2010 & 2014) and from re-assaying a part of the 164 historical drill cores which are well preserved on site. Indicated Resources are defined by a drill grid of 150 metres by 150 metres, while Inferred Resources are defined by a drill grid of 300 metres by 150 metres.
The Haib Copper exploration licence provides significant potential for resource expansion, since there is known, but poorly drilled and assayed, mineralisation beyond the drill grid boundaries and below the main mineralised body (which covers some 2 square kilometres of surface area), where a few drillholes from 75m above mean sea level to -350m above mean sea level (i.e. a thickness of 425m) have shown that mineralisation is present. The deepest drillhole did not pass out of mineralised material. In addition (see map below), there are 5 satellite mineralised target areas surrounding the main Haib porphyry body which still require further evaluation.

Mr. Peter Walker of P & E Walker Consultancy is the main Qualified Person for the 43-101 resource estimation report, which has an effective date of January 15, 2018. A technical report will be filed on SEDAR at www.sedar.com and on the Deep-South website at www.deepsouthresources.com shortly after the issuance of this news release.
Preliminary Economic Assessment underway
With the Haib Copper resources estimate completed, Deep-South has retained Midas Engineering and Technical Services of Perth, Australia, to prepare a Preliminary Economic Assessment (PEA) for the further development of the Haib Copper deposit. The PEA, which is expected to be completed before the end of February 2018, concentrates on establishing the economic parameters of potential mining operations at Haib.
METS has examined the latest metallurgical process technology and reviewed the historical test work to develop conceptual ideas for processing options. METS is using the results of their processing study and the Resource Estimates completed by P & E Walker Consultancy and Obsidian Consulting Services.
The METS Engineering report will consider various mineral processing and metallurgical options that will include, amongst others:
- – Comminution- Heavy Liquid Separation
– Colorimetric Sorting
– Bio-Heap Amenability
– Flotation
Four recovery options are considered for economic evaluation:
- – Option 1: Ore sorter upgrading, dense media upgrading, flotation and heap leaching of the tails.
- – Option 2: Two-stage dense media upgrading, flotation and heap leaching of the tails.
- – Option 3: Ore sorter upgrading and heap leaching of the upgraded material.
- – Option 4: Whole ore heap leaching.
“The Haib Copper PEA will allow Deep-South’s technical team and consultants to maximize opportunities for project enhancements as we move the Haib Copper Project forward,” said Mr. Leveille.
Quality Control and Assurance and data verification
The independent qualified persons for the Haib Copper Mineral Resource estimate are Mr. Peter Walker of P & E Walker Consultancy and Mr. Dean Richards of Obsidian Consulting Services.
Obsidian Consulting Services conducted a review of the QA/QC programme implemented by Teck using the certificates of analysis received from Acme Labs and provided by Teck. This review compared the results of field duplicates, blanks as well as the various standards utilised with respect to Cu and Mo.
The design of Teck’s drilling programme, quality assurance / quality control programme and the interpretation of results were under the control of Teck’s geological staff. The QA/QC programme is consistent with industry best practices. Drill core is logged and cut onsite, with half-core samples prepared at Analytical Laboratory Services, Windhoek, Namibia. Prepared samples are shipped to Acme Analytical Laboratories, Vancouver, Canada for appropriate base metal assaying and gold fire assaying techniques. All analytical batches contain appropriate blind standards, duplicates and blanks inserted at regular intervals to independently assess analytical accuracy and precision.
Mr. Walker and Mr. Richards reviewed the sample chain-of-custody, quality-assurance and quality-control (QA/QC) procedures, and the accreditations of analytical laboratories used by Teck. The QPs are of the opinion that the procedures and QA/QC are acceptable to support Mineral Resource estimation. Mr. Walker also audited the assay database, core logging and geological interpretations and found no material issues with the data as a result of these audits.
In the opinion of the QPs, the data verification programs undertaken on the geological and assay data collected from the Haib Copper support the geological interpretations and the analytical and database quality, and the data collected, can support Mineral Resource estimation.
