Exceptional First Pass Drilling Results

Multiple Broad and High-Grade Gold Drill Intersections

Zaranou Gold Project

Côte d'Ivoire, West Africa

IronRidge Resources Limited (AIM: IRR, 'IronRidge' or the 'Company'), the African focussed minerals exploration company, is delighted to report that multiple high-grade and broad gold intersections have been returned from initial drilling assay results received from the Zaranou Gold Project in Côte d'Ivoire. The license borders with Ghana and is along strike from significant operating gold mines including Chirano (5Moz), Bibiani (5.5Moz) and Ahafo (17Moz).

Figures and Tables referred to in this release can be viewed in the PDF version available via this link:


o Multiple high-grade and broad gold drilling intersections returned from initial assay results received for the maiden exploration drill programme completed at the Zaranou Gold Project.

o Highlight Aircore ('AC') drill intersections reported at a 0.2g/t cut-off and maximum 2m of internal dilution including:

§ 6m @ 15.11g/t gold from 26m, including 2m @ 36g/t and 2m @9.29g/t

§ 22m @ 3.39g/t gold from 8m, including 4m @ 13.55g/t and 4m @ 3.96g/t

§ 2m @ 23g/t gold from 40m

§ 6m @ 6.72g/t gold from surface, including 2m @ 15g/t and 2m @ 3.72g/t

§ 18m @ 0.31g/t gold from 32m, including 2m @ 0.58g/t

§ 10m @ 0.33g/t gold from 40m

§ 2m @ 5.26g/t gold from 18m

§ 2m @ 4.53g/t gold from 40m

o All drill intersections are open along strike and down-dip and replicate or improve on previously announced channel and rock-chip sampling results within the high-priority 8km long target zone with intensive artisanal mining (refer RNS of 23 July 2019).

o Gold mineralisation spatially associated with deformation zones including multiple meter-scale quartz-carbonate-manganese veins up to 30m apparent thickness and strongly crenulated phyllite zones which are broadly coincident with artisanal workings along strike.

o Maiden exploration drill programme now completed for a total of 7,448m of AC in 151 holes and 1,593m of Reverse Circulation ('RC') in 10 holes along seven drill traverses.

o Assay results reported herewith represent 3,489m of AC drilling for 82 holes received to date. Additional AC and RC drilling assay results pending for remaining meterage.

Commenting on the Company's latest progress, Len Kolff, Chief Operating Officer of IronRidge, said:

'Assay results received to date are exceptional for a first-pass exploration drill programme and indicate potential for a significant gold discovery, notwithstanding that only such a small portion of the large target footprint has been drill tested to date.

'Achieving the broad and high-grade gold intersections returned to date as part of a first pass exploration drill programme is a significant result and demonstrates the exploration potential of the Zaranou Gold Project.

'Field work to date has identified over 8km strike length and up to 1.2km width of coincident hard-rock artisanal workings, surface sampling results up to 69.6g/t gold and geophysical anomalies which remains open along strike and has now been drilled along broad spaced AC traverses with initial exceptional results up to 6m @ 15.11g/t and 22m @ 3.39g/t gold.

'This all sits within a broader 40km long alluvial artisanal mining corridor with coincident major geophysical contacts and historical drill collars located in the southern extent; indicating the scale of potential mineralisation.

'Drilling results received to date compare favourably with historically reported results from 2008 including 2.2g/t over 21 meters (including 5.7 g/t over 5 meters) in a limited rotary air blast ('RAB') drilling program.

'Gold mineralisation in drilling is spatially associated with veining and deformation zones which occur along strike of hard-rock artisanal workings; and provides further confidence in continuity of mineralisation within the 8km strike high-priority target zone.

'An additional 1,000m of AC drilling was completed as some traverses were extended and holes drilled deeper than planned due to a thicker weathering profile than estimated.'

Initial Drill Results

Initial drilling results have returned multiple high-grade and broad gold intersections at a 0.2g/t gold cut-off and maximum 2m of internal dilution, with highlights including:

o 6m @ 15.11g/t gold from 26m, including 2m @ 36g/t and 2m @9.29g/t

o 22m @ 3.39g/t gold from 8m, including 4m @ 13.55g/t and 4m @ 3.96g/t

o 2m @ 23g/t gold from 40m

o 6m @ 6.72g/t gold from surface, including 2m @ 15g/t and 2m @ 3.72g/t

o 18m @ 0.31g/t gold from 32m, including 2m @ 0.58g/t

o 10m @ 0.33g/t gold from 40m

o 2m @ 5.26g/t gold from 18m

o 2m @ 4.53g/t gold from 40m

Initial assay results have been returned for AC traverses Line 3, Line 5and Line 6with all drill intersections reported in Table 1and Figure 1through to Figure 4below. All samples were analysed by ALS laboratory in West Africa and passed internal QA/QC protocols providing confidence in reported results.

A total of three (3) AC drill traverses are reported herewith from a total of seven (7) traverses drilled for the maiden drill programme (refer Figure 1). All drill intersections are reported on cross-sections in Figure 2, Figure 3and Figure 4.Drilling results received to date have confirmed strike and depth continuity of gold mineralisation where tested on AC traverses adjacent to hard-rock artisanal pits and shafts as well as discovered new mineralised trends under shallow cover not exposed by artisanals (refer Figure 2, Figure 3and Figure 4). This is significant as it demonstrates additional exploration potential between currently defined gold trends.

New drilling results confirm previously reported channel sampling results including 6m @ 3.67g/t, 3m @ 4.13g/t and 4m @ 2.39g/t gold, and rock chip sampling results including 69.9g/t, 48.8g/t and 25.3g/t gold from within the artisanal pits, providing confidence in further exploration potential along the 8km target zone sampled to date (refer to RNSof 23 July 2019).

Gold mineralisation is spatially associated with deformation zones which include meter-scale quartz-carbonate-manganese veins which extend up to 30m apparent width in places, as well as crenulated phyllite zones; potentially representing high-level signatures of a shear zone (refer Figure 2, Figure 3and Figure 4).

Disseminated sulphide (pyrite), manganese and magnetite have been observed in drill chips within quartz-carbonate veining and the host lithology within the deformation zones.

Drilling results to date confirm interpreted target trends, with high-grade drilling results up to 6m @ 15.11g/tand 22m @ 3.39g/tgold along strike from mapped hard-rock artisanal pits and shafts. This provides further confidence in the overall prospectivity within the 16km long by 500m to 1.2km wide zone of intensive hard-rock artisanal mining, which itself occurs within a larger 40km long striking zone of coincident artisanal alluvial mining and major aeromagnetic contact (refer Figure 1and RNSof 11 November 2019).

Maiden Exploration Drill Programme

The Company has completed a maiden exploration drill programme over approximately 8km strike of the overall 40km long exploration target zone defined at the Zaranou Gold Project (refer RNSof 11 November 2019).The first pass exploration drill programme consisted of 7,448m of AC in 151 holes to an average depth of 50m and maximum of 90m, and 1,593m of RC in 10 holes to an average depth of 160m and maximum of 183m. Drilling was completed along seven (7) traverses ranging from 500m to 850m long (refer Figure 1).Drilling was designed to test below and along strike of previously reported channel sampling results including 6m @ 3.67g/t, 3m @ 4.13g/t and 4m @ 2.39g/t gold, and rock chip sampling results including 69.9g/t, 48.8g/t and 25.3g/t gold from within the artisanal pits (refer to RNSof 23 July 2019).Drilling has provided a first pass test into approximately 8km strike of intensive hard-rock artisanal pitting with coincident sampling and geophysical anomalies and high-grade drilling results returned including 6m @ 15.11g/tand 22m @ 3.39g/t. Pitting remains open a further 5km along strike to the south-west and 3km along strike to the north-east for a combined total 16km strike of hard-rock artisanal pitting within a broader 40km long corridor of alluvial mining; providing confidence in future drill success and the definition of multiple additional targets (refer RNSof 6 June 2019).

Next Steps

Assay results are pending for remaining AC traverses, as well as deeper RC holes, which will be announced when available. Once all results are received and reviewed, the Company will plan follow-up exploration and drill programmes.

Soil sampling along the north-eastern and south-western strike extent of the coincident artisanal alluvial mining and geophysical anomaly is ongoing.

The drone survey continues to generate high resolution imagery and topographic control to assist in exploration programme design and baseline studies.

To date, the drone imagery has provided a valuable insight into mineralised trends (refer RNS of 19 September 2019, and Figure 4) and provides a powerful tool to review imagery in 3D as shown in the embedded link

The Board is delighted with the progress that the Company has made in 2020 to date and looks forward to keeping shareholders updated as further news becomes available.

The tenure package is also highly prospective for tin, tantalum, niobium, caesium and gold, which occur as accessory minerals within the pegmatites and host formations.


The Company entered into an agreement with Tekton Minerals Pte Ltd of Singapore concerning its portfolio covering 900km2 of highly prospective gold and other mineral projects in Chad, Central Africa. IronRidge acquired 100% of Tekton including its projects and team to advance the Dorothe, Echbara, Am Ouchar, Nabagay and Kalaka licenses, which host multiple, large scale gold projects. Trenching results at Dorothe, including 84m @ 1.66g/t Au (including 6m @ 5.49g/t & 8m @ 6.23g/t), 4m @ 18.77g/t Au (including 2m @ 36.2g/t), 32m @ 2.02g/t Au (including 18m @ 3.22g/t), 24m @ 2.53g/t Au (including 6m @ 4.1g/t (including 2m @ 6.2g/t) and 2m @ 6.14g/t), 14.12g/t Au over 4m, 34.1g/t over 2m and 63.2g/t over 1m, have defined significant gold mineralised quartz veining zones over a 3km by 1km area including the steep dipping 'Main Vein' and shallow dipping 'Sheeted Vein' zones.

Côte d'Ivoire

The Company entered into conditional earn-in arrangements in Côte d'Ivoire, West Africa; securing access rights to highly prospective gold mineralised structures and pegmatite occurrences covering a combined 3,584km2 and 1,172km2 area respectively. The projects are well located within access of an extensive bitumen road network and along strike from multi-million-ounce gold projects and mines.


Monogorilby is prospective for province scale titanium and bauxite, with an initial maiden resource of 54.9MT of premium DSO bauxite. Monogorilby is located in central Queensland, within a short trucking distance of the rail system leading north to the Port of Bundaberg. It is also located within close proximity of the active Queensland Rail network heading south towards the Port of Brisbane.

May Queen is located in Central Queensland within IRR's wholly owned Monogorilby license package and is highly prospective for gold. Historic drilling completed during the 1980s intersected multiple high-grade gold intervals, including 2m @ 73.4 g/t Au (including 1m at 145g/t), 4m @ 38.8g/t Au (at end of hole) and 3m @ 18.9g/t Au, over an approximate 100m strike hosting numerous parallel vein systems, open to the north-west and south-east.
