Commenting on the Company's latest progress, Len Kolff, Chief Operating Officer of IronRidge, said:
"Field activities are gaining momentum in Côte d'Ivoire as we enter the dry season.
"Airborne magnetics has been completed over the Vavoua portfolio, with shear zone extensions along strike from the 700Koz Abujar project (JORC compliant) clearly evident; providing structural targets and confidence for ongoing exploration.
"Preliminary soil samples at Marahui have identified mineralised trends; infill soil sampling is underway to confirm trends ahead of potential trenching.
"Trenching will commence in Q1 2019 at Kineta where previously announced soils identified a >30ppb and up to 3.7g/t Au over 2km long and up to 250m wide anomaly with over 700m of coincident artisanal workings.
"Anomalous broad trenching results at Bianouan including 47m @ 0.16g/t gold indicate potential for a mineralised system with possible gold depletion at surface; deeper auger drilling now underway to test the anomaly at depth.
"Auger drilling has resumed over the Bodite target, where early rains temporarily suspended field activities."
Exploration Update
With the arrival of the 2018-2019 dry season, field programmes have commenced across the majority of granted Joint Venture licenses in Cote d'Ivoire. Field teams have been mobilised across the Kineta, Marahui, Bianouan and Bodite licenses to commence and resume fieldwork. South African contractor Xcalibur Airborne Geophysics ('Xcalibur') have completed airborne magnetics surveys over the Vavoua licenses (refer to Figure 1).
Vavoua Airmagnetics:
Xcalibur successfully completed airborne magnetics at 100m line spacing and 35m to 40m ground clearance over the Vavoua portfolio. Preliminary raw magnetics data confirms strike extension over 40km of a major Shear Zone which hosts the 700Koz JORC compliant Abujar project to the south of the Vavoua portfolio.
Australia, Perth based Southern Geoscience Consultants has processed the raw geophysical data to generate the various magnetics, radiometrics and topography deliverables for structural and lithological interpretation. The Company will interpret regolith and high-priority structural targets ahead of a planned regional soils and auger programme. Anomalous due diligence results including 2.3g/t in auger drilling (refer to RNS of 28 March 2017) and the recent discovery of artisanal workings will help prioritise follow-up field programmes (refer to Figure 2).
Marahui Soils:
At Marahui regional soil sampling on a 400m x 50m grid was completed with 3 main gold anomalous trends defined in the soils over 1.5km to 3km strike lengths at average 30ppb to 120ppb gold levels (refer to Figure 3). The Company has mobilised field teams to complete infill soil sampling on a 200m x 50m grid prior to planning the next steps.
The Company is in discussions with the Ministry of Mining and Forestry Commission regarding an overlap between the granted exploration license and a forest reserve in the south of the Mararhui license and outside the area of current work.
Kineta Trenching:
Subsequent to completion of soil sampling at the Kineta license (refer to RNS of 30 July 2018), the Company will commence a 1,000m trenching programme over the main soil anomaly. Three trenches up to 400m long have been planned with field work to commence in the new year. In addition to the trenching, regional mapping, soil sampling and stream sediments have been planned to cover the remainder of the license area to assess for any additional target areas outside of the highest priority target corridor (refer to Figure 4).
Bianouan Trenching and Bodite Deep Auger:
Broad trenching intervals of 47m @ 0.16g/t (including 14m @ 0.23g/t Au), 7m @ 0.18g/t and 4m @ 0.21g/t at the Ketesso target and 11m @ 0.7g/t, 9m @ 0.16g/t, 1m @ 1.1g/t, 3m @ 0.14g/t and 1m @ 0.42g/t at a 0.15g/t Au cut-off with maximum 2m of internal dilution were returned at the Yaw target at the Bianouan project. No significant results were returned from the 19 pits completed. Trenching was designed to follow-up the soil anomalies defined at Bianouan, whilst pitting was designed to follow-up high-grade single point soil anomalies (refer to RNS of 2 May 2018).
Despite trenching depths up to 4m, weathering was still intense with laterite and saprolite evident in the trench wall. Given the broad and continuous low-grade gold anomalous zones defined in trenching coupled with the deep tropical weathering, it is interpreted that trenching has not tested deep enough with potential gold depletion in the sampled horizon and a valid target remaining at depth.
Accordingly, a deep mechanised auger programme of 150 holes to an average planned depth of 7m has commenced to test the coincident soil and trench anomalies at greater depth (refer to Figure 5).
At Bodite, deep auger drilling has resumed after wet weather temporarily suspended field activities. A total of 1,169 auger drill holes on a 50m x 200/400/800m grid over a 9km long gold in soil trend defined during the first phase sampling is planned (refer to RNS of 7 August 2017 and 2 May 2018).
The Board is pleased with the progress that the Company has made to date and looks forward to keeping shareholders updated as further news becomes available.
