ASX/Media Announcement
2 June 2020
New Granite Contact Targets and High-Grade Gold Shoot at Kouri
Key Points:
-
An updated geological interpretation following receipt of new data has highlighted that the contact areas between granites and surrounding volcanic rocks appear to be favourable depositional sites for gold mineralisation.
-
The updated geological interpretation has identified a number of new granite contact target areas that have the potential to host high-grade gold.
-
Two prospects with granite contact target areas have been prioritised for the next drilling campaign:
Diabatou Prospect
-
2.6km x 1.2km granite intrusion outlined in the updated geological interpretation.
-
High-grade results received from previous drilling along the southern granite contact area of this intrusion are now interpreted to lie within the upper portion of a steeply plunging high-grade gold shoot, now known as the Diabatou Gold Shoot, which remains open at depth and along strike.
-
The discovery of the Diabatou Gold Shoot is significant as elsewhere in Burkina Faso, steeply plunging, high-grade gold shoots discovered in granite contact areas can extend vertically for more than 1km and host more than 1Moz of gold.
-
As a priority, Golden Rim’s next drilling at the Diabatou Prospect will target extensions to the mineralisation of the Diabatou Gold Shoot.
-
A 750m long gold auger anomaly (up to 157ppb gold ) along the northern granite contact offers an additional new drill target at the Diabatou Prospect.
Mirga Prospect
-
3.2km x 1.5km granite intrusion outlined in the updated interpretation, 3km NE of the 1.4Moz Mineral Resource.
-
1km long gold auger anomaly (up to 200ppb gold ) with coincident anomalous rock chip samples results (up to 11.7g/t gold ) along the southern contact of the granite intrusion offers a new drilling target.
-
Further drilling results received NE of the 1.4Moz Mineral Resource at Kouri has extended the NE strike of the gold lodes that comprise the Mineral Resource to 650m . The gold lodes remain open.
-
COVID-19 travel restrictions within Burkina Faso have been eased and access to Kouri is again possible.
-
Golden Rim is expecting to recommence field work at Kouri on 3 June 2020.

Kouri Granite-Target Interpretation
An updated geological interpretation for Kouri based on newly acquired ASTER imagery, previous geophysical data (airborne and ground magnetics and Induced Polarisation), satellite imagery, bottom of auger hole geology and geological mapping has been completed (Figure 1).
A number of granite intrusions that lie within the Samira Hill Shear Zone at Kouri have been identified (Figure 1). It is believed these granites are younger than the surrounding older basement granites and were largely emplaced prior to the deposition of the gold mineralisation along the Samira Hill Shear Zone.
The contact areas between the granites and the surrounding volcanic rocks are believed to have provided favourable depositional sites for gold mineralisation and offer Golden Rim a number of highly prospective additional target areas for exploration.
While new granite contact target areas have been identified within at least eight prospect areas, two prospects (Diabatou and Mirga) have been prioritised for the next drilling campaign.

Diabatou Prospect
The updated geological interpretation has outlined a 2.6km x 1.2km granite intrusion that wraps around a central embayment of volcanic rocks at the Diabatou Prospect (Figure 2).
Two particular areas of interest have been identified for follow-up exploration.
The first of these relates to the contact area between a granite and a narrow embayment of volcanic rocks that lies in the southern portion of the granite intrusion.
Previous drilling along this contact intersected an east-west-trending, high-grade zone of gold mineralisation beneath a 200m long zone of artisanal workings. Drilling intersections included:
-
9m at 3.6g/t gold from 49m, including 1m at 15.1g/t gold from 50m (MRC016);
-
6m at 9.5g/t gold from 63m, including 1m at 20.9g/t gold from 63m & 1m at 27.0g/t gold from 66m (MRC026); and
-
4m at 12.6g/t gold from 77m, including 2m at 22.5g/t gold from 78m (MRC027).
This drilling is now interpreted to lie within the upper portion of a steeply plunging high-grade gold shoot ( Diabatou Gold Shoot ), which remains open at depth and along strike (Figure 3). Results to date suggest the gold grade within the shoot may be increasing to the east and at depth. Golden Rim’s next drilling at the Diabatou Prospect will target extensions to the mineralisation in these areas.
The discovery of the Diabatou Gold Shoot is significant as elsewhere in Burkina Faso, steeply plunging, high-grade gold shoots discovered in granite contact areas are known to host more than 1Moz of gold. While the strike extent of these shoots can be limited (e.g. several hundred metres) they can extend vertically for more than 1km (Figure 4). For example:
-
Roxgold (TSX:ROXG) has outlined a Mineral Resource of 1.1Moz at 13.9g/t gold in the Zone 55 Shoot at the Yaramoko Gold Mine in a granite – basalt contact zone; and
-
Western African Resources (ASX:WAF) has outlined a Mineral Resource of 1Moz at 14.1g/t gold in the M1 South Shoot in a granodiorite – meta-sediment contact zone.
The second area of interest at the Diabatou Prospect is a 750m long gold auger anomaly where previous sample results up to 157ppb gold were obtained. The gold auger anomaly appears to be associated with the northern contact of the granite intrusion and offers an additional new drill target (Figure 2).
Mirga Prospect
At the Mirga Prospect, a 3.2km x 1.5km granite intrusion which lies approximately 3km NE of the 1.4Moz Mineral Resource, has been outlined in the updated geological interpretation (Figure 1).
Along the southern contact of the granite intrusion a 1km long gold auger anomaly, with previous sample values up to 200ppb gold and coincident previous anomalous rock chip samples results up to 11.7g/t gold , offers a new drilling target.

Mineral Resource Area
Assays have been received for a further 4 reverse circulation ( RC ) drill holes (GRC011, GRC014, GRC015, GRC017) located along strike to the NE of the 1.4Moz gold Mineral Resource area.
The details for these new drill holes are provided in Table 1. The new assay results are listed in Table 2 and depicted in Figure 5.
Gold mineralisation was intersected in all four holes. The best intercept is 5m at 1.0g/t gold from 42m in GRC017.
The results extend the NE strike of the gold lodes that comprise the Mineral Resource to 650m and the strike of the gold lodes remain open.

Licence Status
The Company is pleased to advise that it has received its first permit renewal for the Kouri Permit (Figure 1), which is where the 1Moz gold Mineral Resource is located. The Kouri Project is comprised of 3 permits (Kouri, Gouéli and Margou). In Burkina Faso, each exploration permit is issued for 3 years and can be renewed for 2 further 3 year periods so that in total, an exploration permit can be held for 9 years.
The Company is also pleased to advise that the Gouéli Permit has been transferred to the Company’s 100% wholly owned Burkina Faso subsidiary, Nemaro Gold SARL. Previously, the permit had been held in trust pending the transfer.
New Business Development
As previously advised, the Company has been investigating new business development opportunities.
Currently there is a strong appetite in the gold market. The Company believes that the Kouri Gold Project offers much upside potential to take advantage of this strong interest and is looking forward to commencement of the next drilling program.
The Company also believes that there is value in holding more than one gold project in one jurisdiction. Therefore, it continues to investigate new business opportunities across the African continent, including greenfield and very advanced gold project opportunities.

==> picture [595 x 85] intentionally omitted <==
As we recover from the immediate effects of the COVID-19 pandemic, the Company aims to be both upgrading its Mineral Resource at Kouri while moving toward a more diversified gold portfolio.
Corporate
The Company advises that 67,179,613 of its fully paid ordinary shares will no longer be subject to voluntary escrow, on 28 June 2020.
Recommencement of Exploration
With the easing of COVID-19 restrictions in Burkina Faso, Golden Rim is expecting to recommence exploration at Kouri on 3 June 2020. Initially, field checking will be conducted over the new granite contact target areas and follow up drill hole locations will be planned. RC drilling is expected to follow later in the month.
Commenting on the Company’s latest activities, Golden Rim’s Managing Director, Craig Mackay, said:
“A break in field work during the COVID-19 pandemic has given us an excellent opportunity to review our existing and extensive geological, geochemical and geophysical data sets for Kouri. Together with newly purchased ASTER data we have prepared a updated geological interpretation for Kouri.
We have identified a number of previously unknown granite intrusions along the Samira Hill Shear Zone that extends for 40km through Kouri and we believe granite contact areas offer highly prospective new targets for Golden Rim.
We have previously drilled four holes on one of these granite contact areas at the Diabatou Prospect. All four holes hit high-grade gold and we believe we have discovered the upper portion of a high-grade gold shoot.
In Burkina Faso, such high-grade gold shoots can extend for more than 1km below surface and host more than 1Moz of gold.
We look forward to testing for extensions to the gold shoot at Diabatou when we re-commence of our drilling.”

Appendix 1: JORC Code (2012 Edition), Assessment and Reporting Criteria
Section 1: Sampling Techniques and Data
| Criteria | JORC Code Explanation | Explanation |
|---|---|---|
| Sampling Techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. |
The sampling described in this report refers to reverse circulation (RC) drilling. RC samples are collected by a three-tier riffle splitter using downhole sampling hammers with nominal 127 to 140mm holes. Samples were all collected by qualified geologists or under geological supervision. The samples are judged to be representative of the rock being drilled. The nature and quality of sampling is carried out under QAQC procedures as per industry standards. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Sampling is guided by Golden Rim’s protocols and Quality Control procedures as per industry standards. To ensure representative sampling, 1m RC samples are collected from a cyclone, passing them through a 3-tier riffle splitter (producing a 2kg sample). Duplicate samples are taken every 30thsample. Measures were taken to avoid wet RC drilling. |
|
| Aspects of the determination of mineralisation that are Material to the Public Report. |
Samples were submitted to BIGS Laboratory and ALS Laboratories in Ouagadougou for preparation and analysis. The entire sample is dried, coarse crushed and pulverised to better than 85% of the material passing through a 75-micron (Tyler 200 mesh) screen. RC samples have been assayed by either Fire Assay or BLEG analysis. Fire Assay: A 200g sub-sample is taken from the samples for analysis. A 50g charge weight is fused with litharge-based flux, cupelled and the prill dissolved in aqua regia and gold tenor is determined by AAS. BLEG: Gold by accelerated cyanide leach using LeachWELL assay tablets over 4 hours with AAS finish on a 1kg sample. |
|
| Drilling Techniques |
Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
The RC rig is EDM 2000 with rods diameter of 114,3mm. All drill holes were planned to be drilled an optimum angle for intersecting the mineralisation (50 to 60 degrees). Downhole surveying occurred (where-ever possible) at 30m intervals down hole. The location of each hole and rock chip sample was recorded by handheld GPS with positional accuracy of approximately +/-5m. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
All RC samples are weighed to determine recoveries. Samples are recovered directly from the rig (via the cyclone and a 3-tier riffle splitter) in 1m intervals. |
Page | 10
==> picture [595 x 85] intentionally omitted <==
| Criteria | JORC Code Explanation | Explanation |
|---|---|---|
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
All drill samples are visually checked for recovery, moisture and contamination. A technician is always present at the rig to monitor and record recovery. Recoveries are recorded in the database. There are no significant sample recovery problems. The RC rig has an auxiliary compressor and boosters to help maintain dry samples. When wet samples are encountered, the RC drilling is discontinued. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
No relationship is seen to exist between sample recovery and grade. No sample bias is due to preferential loss/gain of any fine/coarse material due to the acceptable sample recoveries obtained by both drilling methods. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
Logging of drill samples recorded lithology, mineralogy, mineralisation, weathering, alteration, colour and other features of the samples. The geological logging was done using a standardised logging system. This information and the sampling details were transferred into Golden Rim’s drilling database. All drilling has been logged to a standard that is appropriate for the category of Resource which is being reported. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
Logging is both qualitative and quantitative, depending on the field being logged. |
|
| The total length and percentage of the relevant intersections logged. |
100% of each relevant intersection is logged in detail. | |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
No core in this report |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
RC samples were collected on the rig using a three-tier riffle splitter. The majority of the samples were dry. On the rare occasion that wet samples were encountered, they were dried prior to splitting with a riffle splitter. The standard RC sample interval was 1m. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Samples were transported by road to BIGS Laboratory and/or ALS Laboratory in Ouagadougou. The sample preparation for all samples follows industry best practice. At the laboratory, the entire sample is dried, coarse crushed and pulverised to better than 85% of the material passing through a 75-micron (Tyler 200 mesh) screen. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
Golden Rim has protocols that cover the sample preparation at the laboratories and the collection and assessment of data to ensure that accurate steps are used in producing representative samples. |
Page | 11
==> picture [595 x 85] intentionally omitted <==
| Criteria | JORC Code Explanation | Explanation |
|---|---|---|
| The crusher and pulveriser are flushed with barren material at the start of every batch. |
||
| Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. |
Sampling is carried out in accordance with Golden Rim’s protocols as per industry best practice. Field QC procedures involve the use of certified reference material as assay standards, blanks and duplicates for the auger samples. Field duplicates were taken on 1m RC splits using a riffle splitter. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
The sample sizes are considered appropriate to correctly represent the style of mineralisation, the thickness and consistency of the intersections. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
Fire Assay: A 200g sub-sample is taken from the RC samples for analysis. A 50g charge weight is fused with litharge-based flux, cupelled and the prill dissolved in aqua regia and gold tenor is determined by AAS. BLEG: Gold by accelerated cyanide leach over 4 hours using LeachWELL assay tablets with AAS finish on a 1kg sample. The analytical method is considered appropriate for this mineralisation style and is of industry standard. The quality of the assaying and laboratory procedures are considered to be appropriate for this deposit type. |
| For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |
No geophysical tools were used to determine any element concentrations. |
|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Sample preparation checks for fineness were carried out by the laboratory as part of their internal procedures to ensure the grind size of 90% passing 75 microns. Internal laboratory QAQC checks are reported by the laboratory. Review of the internal laboratory QAQC suggests the laboratory is performing within acceptable limits. For RC samples, Golden Rim inserts one blank, one standard and one duplicate for every 30 samples. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Reported results are compiled and verified by the Company’s Senior Geologist and the Managing Director. |
| The use of twinned holes. | None of the drill holes in this report are twinned. | |
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Primary field data is collected by Golden Rim geologists on standardised logging sheets. This data is compiled and digitally captured. |
Page | 12
==> picture [595 x 85] intentionally omitted <==
| Criteria | JORC Code Explanation | Explanation |
|---|---|---|
| The compiled digital data is verified and validated by the Company’s database geologist. |
||
| Discuss any adjustment to assay data. | The primary data is kept on file. There were no adjustments to the assay data. |
|
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
Drill Collar locations and rock chip sample locations were recorded by handheld GPS with a positional accuracy of approximately +/- 5 metres. Down-hole surveys were completed at the end of every drill hole (where possible) using a Reflex down-hole survey tool. Measurements were taken at approximately every 50 meters. At the completion of the program all holes will be surveyed with a DGPS, which has locational accuracy of +/- 0.1m, X, Y and Z. |
| Specification of the grid system used. | Location data was collected in either UTM grid WGS84, zone 31 North or UTM grid WGS84, zone 30 North |
|
| Quality and adequacy of topographic control. | Topographic control was established by using a survey base station. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | Drilling is conducted has been conducted along lines, with holes spaced at 25 to 50m along that line. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
Drill collar spacing and distribution are sufficient for exploration drilling. |
|
| Whether sample compositing has been applied. | There was no sample composting. | |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. |
All drill holes reported here were drilled approximately at right angles (150 or 180 degrees) to the strike of the target mineralisation. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
No orientation-based sampling bias has been identified in the data at this point. |
|
| Sample security |
The measures taken to ensure sample security. | Samples are stored on site prior to road transport by Company personnel to the laboratory in Ouagadougou, Burkina Faso. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
There has been no external audit or review of the Company’s techniques or data. |

Section 2: Reporting of Exploration Results
Criteria |
JORC Code explanation |
Explanation |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. |
The reported drilling results are from the Kouri, Gouéli and Margou permits. Golden Rim owns 100% of the permits. |
| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
Tenure is in good standing. | |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
The area that is presently covered by the Kouri Project has undergone some previous mineral exploration. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Kouri Project covers part of a highly prospective Lower Proterozoic Birimian, Samira Hill Greenstone belt and is traversed by a significant NE-trending fault splay which is connected to the major Markoye Fault system. This fault system controls several major gold deposits in Burkina Faso, including Kiaka (5.9 Moz), Bomboré (5.2 Moz) and Essakan (7 Moz). The mineralisation lies in a package of highly altered volcanic and volcaniclastic host rocks and is associated with a major gold-in-soil anomaly and a prominent dilational structural jog along a regional NE-trending shear zone. |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. |
The body of the report contains tables summarising the RC location data (Hole ID, Easting, Northing, Dip, Azimuth and total Depth) and a list of significant (gold ≥ 0.3g/t for the Mineral Resource) intercepts. Appropriate locality maps for some of the holes also accompanies this announcement. Further information referring to the drill hole results can be found on Golden Rim’s website http://www.goldenrim.com.au/site/News-and-Reports/ASX- Announcements |
| If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |

| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
RC samples are taken at 1m intervals. For the 0.3 g/t Au cut-off calculations, up to 3m (down hole) of internal waste, unless the total intercept grade falls below 0.3 g/t gold (Mineral Resource). No weighting or high-grade cutting techniques have been applied to the data reported. Assay results are quoted rounded to 1 decimal place. |
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
Not applicable in this document as no exploration results are announced. |

| Criteria | JORC Code explanation | Explanation |
|---|---|---|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Metal equivalent values are not reported in this announcement. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
The reported drilling results are from exploration drilling, designed to test possible extensions to the known Mineral Resource. |
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
The orientation of the mineralised zone has been established and the RC drilling was planned in such a way as to intersect mineralisation in a perpendicular manner. |
|
| If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
Not applicable in this document | |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Maps are provided in the main text. |
| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
The accompanying document is considered to represent a balanced report. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
There is no other exploration data which is considered material to the results reported in the announcement. |
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). |
Promising results will be followed up (where practicable) with trenching and further RC or diamond drilling. Exploration and infill drilling will continue to target projected lateral and depth extensions of the mineralisation and to increase the confidence in the Mineral Resource. |
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
