Vancouver, British Columbia — September 17, 2020 – Tembo Gold Corp. (TSXV: TEM) (“Tembo” or the “Company”) is pleased to provide this geological information on the Ngula 1 target, Tembo Project.
Historical and Pre-drilling Exploration Results
- Prior to the drilling programmes conducted during the 2011-12 and 2014 exploration campaigns, Ngula 1 had returned two anomalous soil values and five reverse circulation drill holes had been drilled along a close-spaced drill fence to intersect beneath a linear array of shallow artisanal shafts trending northeast.
- High resolution airborne magnetics had defined subparallel east west magnetic lineaments and weak northeast trends along interpreted sub-vertical structures.
- LIDAR conducted as a precursor to the drill programme of December 2011, and 2012, revealed extensive workings at Ngula 1 along and adjacent to two east west striking zones.
- Extensive surface workings had exploited a rubble zone over an area of 100-150m by 200-300m along a southern area, and a 100-150m by 150-200m area along a northern area.
- Regolith mapping shows that the area is covered in transported slope scree material that totally conceals all underlying geology and mineralisation, only now revealed through the chance discovery by artisanal workers.
- Within the areas of rubble mining revealed by the ortho-photographic imagery and the digital elevation model produced by the LIDAR survey, numerous linear subparallel east-west trending arrays of vertical artisanal shafts to hard rock are clearly evident, and less well-developed northwest and northeast trends.
- The airborne magnetic data interpretation coincides closely with the linear shaft arrays, a key feature assisting in the interpretation of the local geology and controls on mineralisation.
- The southern of the two zones at Ngula 1 was selected as the first drill target and diamond (DDH) and reverse circulation (RC) drilling commenced in December 2011 and the immediate positive results announced in March 2012.
- This southern zone is approximately 150m wide and appears to consist of two main east-west subparallel shaft arrays but with scattered deep vertical shafts between these suggesting a number of probably subparallel mineralised shears.
Drilling Results, 2012 and 2014
- Drill holes at Ngula 1 were planned on an initial 100m spacing along strike and targeted to penetrate the projected downdip extent of the artisanal linear features at -50m, -100m and -150m.
- All drill holes were designed to drill to 300m, effectively testing between surface and -200m vertical, and to be drilled from the north and south, a necessity to achieve intersections along both the zones at the desired depths.
- The first diamond drill hole TDD0004 intersected 25.89m @ 3.13g/t Au from a depth of 41.00m, including a number of higher-grade zones 2.90m @ 4.15g.t Au from 41.60m, 2.00m @ 12.71g/t from 60m, 3.89m @ 8.78g/t Au from 63.00m.
- The mineralisation consists of disseminated and stringer pyrrhotite and pyrite within a shear zone characterised by chlorite, carbonate and silica alteration and intrafolial quartz veins in a metabasaltic host.
- This result highlights the potential on the Tembo Project for wide near surface mineralisation, as well as deeper high grade and narrower mineralisation, capable of exploitation by open pit and underground mining methods respectively.
- The first RC drill hole TRC0013, collared 100m to the east of TDD0004, returned equally positive results, 3.00m @ 16.10g/t Au from 19.00m, 6.00m @ 2.18g/t Au from 85.00m, 3.00m @ 4.01g/t Au from 103m and 2.00m @ 2.86g/t Au from 248m.
- These initial two holes generated significant interest and confidence in the Ngula 1 target.
- 76 recent drill holes totaling 16,730m have been drilled at Ngula 1, 35 DDH totalling 9,107m and 41 RC totalling 7623m.

Future Drill Planning
- The Ngula 1 target has clearly demonstrated the presence of both wide low-grade and narrower high-grade mineralisation.
- The target has also confirmed that significant structural trends hosting gold mineralisation in multiple sub-parallel structures exist within an east-west corridor in excess of 600m in strike and some 150 to 200m wide.
- The presence of multiple similar magnetic lineaments throughout the Tembo Project greenstone package imply further potential targets exist that have not been tested and have not been exploited by artisanal operators and are also concealed by the transported cover.
- The Ngula 1 target almost certainly warrants further drilling and future programmes will include closer spaced drilling around significant intersections as well as deeper and along strike drilling.
- The technical collaboration with GoldSpot, presently underway (see press release dated August 20, 2020, https://www.newsfilecorp.com/release/62139/Tembo-Gold-Technical-Collaboration-Agreement,) will highlight this and other similar targets within the Tembo licence area and establish the drilling and work programme priorities.
- Further updates and information will follow covering the Nyakagwe Village and Nyakagwe Village targets.
David Scott, President & CEO, stated, “The drilling conducted at Ngula 1 highlighted the potential not just of this target, with some outstanding results, but the potential of the entire greenstone fragment, within which we have only conducted limited drilling within an area of 10km2 on which the focus has been. Much remains to be done and further success is anticipated. Depending on the prioritization established through the current technical review, our aim is to fast track resource definition through focused drill programmes.”
A stringent QA/QC practice is being applied to all sample batches. A Verified Reference Material standard is inserted every 20th sample, a known blank or blank standard every 20th sample and all samples with assays greater than 0.5g/t are re-assayed. 1% of all samples are submitted to an alternative laboratory for check analysis. In addition the laboratory adheres to an internal QA/QC procedure including standard samples and repeats and blanks inserted independently.
