PERTH, Aug. 14, 2018 - Perseus Mining Ltd. (“Perseus” or the “Company”) (TSX & ASX: PRU) is pleased to provide an update on its recent exploration activities at its Sissingué and Yaouré properties, both located in Côte d’Ivoire.
Sissingué, Perseus’s second gold mining operation, started commercial production on April 1, 2018 and the Company is now aiming to extend the currently estimated five-year life of the mine by identifying additional Mineral Resources that can be processed at Sissingué. Recent exploration drilling has identified open ended gold mineralisation extending over 200m of strike length at the Zanikan prospect, south of Sissingué, and over 300m of strike length at the Fimbiasso South prospect on the near-by Mahalé exploration licence. Both prospects are located within trucking distance of the recently commissioned Sissingué processing facility.
Yaouré is a development stage project and will become Perseus’s third gold mine when developed. A positive Definitive Feasibility Study (“DFS”) was completed in October 2017 and subject to financing and full permitting, mine development is expected to start early in 2019. Perseus has completed the drilling of targets identified during the Yaouré DFS as having potential to increase Mineral Resources, Ore Reserves and the currently estimated eight and a half year mine life for the project. Publication of an updated Mineral Resource estimate is now expected in early October 2018, subject to the receipt of all outstanding assay results.
Exploration results are provided below. However, the figures and tables referred to below are included in the full release which is available for download from www.perseusmining.com, www.asx.com.au and www.sedar.com.
Sissingué Exploitation Permit – Zanikan Prospect (Refer to Figure 1)
At Zanikan, 20km south of the Sissingué gold mining operation, Perseus has completed 30 air core (“AC”) drill holes for 1,983m to cover an area of strong gold-in-soil anomalism and extensive artisanal mining of gold mineralised quartz stockworks. This recent AC drilling was designed to undercut previous rotary air blast (“RAB”) drilling and investigate the stockwork mineralisation at greater depths (refer to Figure 2). Three holes from this program returned significant results, including:
Hole | Intercept |
ZNAC010 | 61m @ 1.11g/t from surface and ending in mineralisation, including: • 16m @ 1.56g/t Au from surface, including: - 4m @ 2.02g/t Au from 4m - 4m @ 2.96g/t Au from 12m • 8m @ 1.56g/t Au from 24m • 4m @ 1.75g/t Au from 40m • 9m @ 2.92g/t Au from 52m (EOH) |
ZNAC005 | 12m @ 1.27g/t Au from 32m, including 4m @ 2.3g/t |
ZNAC009 | 4m @ 3.42g/t Au from 48m |
The results appear to indicate multiple steeply west-dipping mineralised structures over an open ended 200 metre strike length. (Refer to cross sections shown in Figures 3-5.) Perseus is planning further AC and reverse circulation (“RC”) drilling to infill, extend and undercut the coverage between and along strike from the recent drilling at the conclusion of the current wet season. A complete summary of the recent Zanikan drilling, including 11 holes drilled at the nearby Gbeni prospect (best intersection 8m @ 0.5g/t Au from GBAC004) is included in Appendix A - Table 1.
Mahalé Exploration Permit – Fimbiasso South Prospect (Refer to Figure 1)
At Mahalé, 40km southwest of Sissingué, 195 AC drill holes totalling 5,586m were drilled, focussing on the southern section of the Fimbiasso granite where 2017 RAB hole MHRB057 intersected 12m @ 1.67 g/t Au. Results from this program were partially reported in Perseus’s June 2018 Quarter Report released to the ASX on July 13, 2018. Since then, Perseus has received further results from the drill program, confirming the prospectivity of this zone, including:
Hole | Intercept |
MHAC1017 | 15m @ 1.23g/t Au from 16m, including 4m@2.58g/t, ending in mineralisation |
MHAC1016 | 5m @ 0.81g/t Au from 28m, ending in mineralisation. |
MHAC1028 | 8m @ 1.19 g/t Au from 16m, including 4m @ 2.05g/t. |
MHAC1027 | 8m @ 0.92g/t Au from 8m. |
MHAC1025 | 4m @ 1.38g/t Au from 20m. |
Geological interpretation suggests mineralisation identified at Fimbiasso South is similar to that found at the Fimbiasso East and West deposits (previously Bélé East and West – Refer to Figure 6), which have a combined JORC Inferred Mineral Resource Estimate of 1.9Mt at 2.0g/t gold for 130,000oz gold.
Recent drilling has confirmed gold mineralisation over at least 300 metres which remains open along strike in both directions, with a possible subparallel zone approximately 100m to the south (Refer to Figure 7). Perseus will undertake additional AC and RC drilling to infill, extend and undercut the coverage between and along strike from the recent drilling following the end of the current wet season. A complete summary of the recent Mahalé drilling is included in Appendix A - Table 2.
Yaouré Exploration Permit – Yaouré and CMA Deposits
The Yaouré DFS identified targets with potential to increase the Yaouré Project’s Mineral Resources and Ore Reserves. By the end of July 2018, Perseus completed the first stage of drilling, targeting high priority targets. The program included 47 holes for 4,597m of RC drilling and 3,849m of core drilling at CMA, 54 holes for 4,896m of RC drilling at Yaouré pit south and 28 holes for 1,930m of RC drilling at Y2 South (Figure 8 and 9).
While many of the assay results from the drilling programme remain outstanding, including significant further assays from AC drilling of the CMA-NE zone, the initial results from the program, with hole locations shown in plan in Figures 10, 12, 14 and 16 and in cross section in Figures 11, 13, 15 and 17, include the following:

Remaining assay results are expected by the end of August 2018 and will be used to update Yaouré’s Mineral Resources and Ore Reserve estimates. This work is expected to be complete late in the September 2018 Quarter.
A complete summary of the recent Yaouré drilling is included in Appendix A - Tables 3A – 3D.
Perseus Managing Director and Chief Executive Officer Jeff Quartermaine said: “We are certainly encouraged by the recent exploration results at Zanikan and Fimbiasso South and are planning further work to follow these results up as soon as weather permits. An increase in the mine life of Sissingué through the addition of further Mineral Resources to the mine’s inventory will materially add to the value of this asset and based on the results achieved to date, this now appears achievable.” “Our drilling at Yaouré has also produced strong results and updating Yaouré’s Mineral Resource and Ore Reserve estimates is our next priority as this should further improve the already attractive economics of developing this outstanding project into our third gold mine and will enhance the project’s appeal to prospective financiers.” |
