The shoot remains open at depth and we have an exciting target for planned deeper diamond drilling, scheduled to commence after the rainy season. Given the Company’s success in discovering granite contact related high-grade gold in the Diabatou Gold Shoot, the next drilling campaign will also test a number of additional granite contact target areas at Kouri that have only recently been identified.
We are expecting our consultants to commence an update to the existing 1.4Moz Mineral Resource that was prepared in November 2018 next week. Since that time Golden Rim has completed 27km of drilling in 211 holes and has outlined additional gold mineralisation along strike from the Mineral Resource and at the Red Hill, Maré and Diabatou prospects which will be incorporated in the update.”

West African gold explorer, Golden Rim Resources Ltd (ASX: GMR) ( Golden Rim , Company ), is pleased to provide its latest drilling results from its Kouri Gold Project ( Kouri ) in Burkina Faso.
Assays have been received for all 20 reverse circulation ( RC ) drill holes (MRC034 – MRC053; for a total of 2,600m) completed in the latest drilling program, which was conducted at the Diabatou Prospect.
The RC program has now been suspended due to the onset of the rainy season, which is expected to last for approximately 2 months.
The location details for the new drill holes are provided in Table 1. The new assay results are listed in Table 2 and depicted in Figures 1 – 4.

Diabatou Gold Shoot
A total of 12 new RC holes (MRC34 – 40; 46, 47, 49, 50, 53) have been completed at the Diabatou Gold Shoot (at the Diabatou Prospect) to follow-up high-grade gold intersections obtained in four previous holes (MRC016, 26 – 28) beneath a 200m long zone of artisanal workings (Figures 1 and 2).
All the new holes intersected a distinct and continuous zone of intense shearing, up to 10m wide, hosted along a granitemafic volcanic contact. The shear zone strikes 070 – 075[0] and dips 65 – 70[0] south.
Within the shear zone, a 100m long, steeply plunging, high-grade gold shoot has been outlined (Diabatou Gold Shoot). Gold mineralisation is associated with quartz-pyrite veins, quartz-pyrite breccia (granite and mafic volcanic fragments) and disseminated pyrite. This shoot remains open at depth. New drilling intersections from the Diabatou Gold Shoot (0.5g/t gold cut-off) include:
-
7m at 4.6g/t gold from 191m (MRC050) including:
-
3m at 10.2g/t gold from 192m; and
-
1m at 17.7g/t gold from 192m;
-
2m at 14.4g/t gold from 141m (MRC040), including:
-
1m at 24.6g/t gold from 141m;
-
2m at 4.4g/t gold from 57m (MRC034); and
-
4m at 1.1g/t gold from 153m (MRC053).

The location of the holes on the Diabatou Gold Shoot are depicted on Figure 2. Drill sections for lines 9,950mE and 10,000mE, which are located across the centre of the gold shoot, are provided as Figures 3 and 4.
MRC050 is the deepest drill hole completed within the shoot to date and it lies 160m vertically below surface and 85m beneath the previous drilling (Figures 1 and 3).
MRC046 was completed at a downhole depth of 140m and may not have been deep enough to intersect the gold shoot (Figure 3). MRC049 was completed at a downhole depth of 150m. Whilst the bottom of this hole intersected 7m at 4.6g/t gold it may not have been deep enough to test the full width of the mineralised zone.
Drilling is expected to re-commence at Kouri in early October 2020 following the rainy season with initial deeper diamond drilling planned for the Diabatou Gold Shoot and the extension of holes MRC046 and MRC049.

Additional Drilling at the Diabatou Prospect
A single hole (MRC044) was drilled beneath previous holes that returned 7m at 121.2g/t gold from 41m, including 1m at 783.8g/t gold (MRC008) and 4m at 23.3g/t gold from 67m, including 1m at 65.7g/t gold (MRC014) on an interpreted northwest-trending cross-structure hosted in the granite intrusion at the Diabatou Prospect (Figure 5). MRC044 returned 1m at 28.1g/t gold , from 41m and has confirmed that the true width of the cross-structure may be around 1m and that the previous holes were largely drilled down-dip. Although narrow, the very high gold grades in the cross-structure warrant further follow-up.
Three holes (MRC048, 51, 52) were drilled approximately 200m south of the Diabatou Gold Shoot to test a parallel, granite hosted, structure outlined in magnetics and Induced Polarisation geophysical data with a coincident gold auger anomaly (up to 850ppb gold) (Figure 5). MRC052 returned 1m at 5.0g/t gold , from 21m, confirming the structure is mineralised. The structure extends for at least 500m and further drilling is planned.
Three holes (MRC041 – 43) were drilled along the northern contact of the granite intrusion at the Diabatou Prospect to test a 750m long gold auger anomaly where previous sample results up to 157ppb gold were obtained (Figure 5). Narrow, low grade gold intersections were received in the drilling and no further exploration is planned in this area.

Significance of the Diabatou Gold Shoot
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 they can extend vertically for more than 1km (Figure 6). 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 current dimensions of the Diabatou Gold Shoot are similar to those of the upper portion of high-grade M1 South Shoot being mined by West African Resources approximately 100km southwest of Kouri (Figure 6).

Mineral Resource Update
Golden Rim’s existing 1.4Moz Mineral Resource was prepared by independent consultants RPM Advisory Services Pty Ltd ( RPM ) during November 2018 and released to the ASX on the 3 December 2018. The Mineral Resource was reported above an elevation of 155m (~115m below surface). An economic cut-off grade of 0.3g/t gold and the average depth of open pit mining were determined following a high level mining study based on a gold price of US$1,300/oz.
Since that time, 27,254m of drilling (211 holes) has been completed at Kouri and the gold price has increased by almost 50%. Additional gold mineralisation which will be incorporated in the Mineral Resource update has been outlined in the northern portion of the Mineral Resource, to the NE of the Mineral Resource (650m strike extension), to the SW of the Mineral Resource (500m strike extension) and at the Red Hill, Maré and Diabatou prospects (Figure 7).

This ASX Announcement was authorized for release by the Board of Golden Rim Resources Ltd.
About Golden Rim Resources
Golden Rim Resources Limited is an ASX listed exploration company with a portfolio of advanced minerals projects in Burkina Faso and Guinea, West Africa and in Chile, South America.
The Company discovered and has outlined a 1.4Moz Mineral Resource at the Kouri Gold Project, located in north-east Burkina Faso. Kouri is currently Golden Rim’s flagship project and it covers 325km[2] of highly prospective Birimian greenstones. As exploration progresses, significant additional gold mineralisation, including a high-grade gold shoot, has been discovered and the gold inventory at Kouri is expected to grow.
The Company recently announced an agreement to acquire the Kada Gold Project in eastern Guinea. Guinea remains one of the most under-explored countries in West Africa. Kada was previously explored by Newmont who completed 34km of drilling and defined a non-JORC gold resource. With infill drilling Golden Rim believes a maiden JORC Mineral Resource can be defined at Kada in the near-term.
In northern Chile, Golden Rim has the Paguanta Silver-Lead-Zinc-Copper Project. Historically a silver mine, the Company has outlined a Mineral Resource comprising 6.8Moz silver, 74Mlb lead and 265Mlb zinc at Paguanta. The Mineral Resource remains open. In addition, the project has several exceptional porphyry-copper targets that remain untested. With Golden Rim’s focus on gold in West Africa, the Company is seeking to divest the project.

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 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. |
|
| 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. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
All drill samples are visually checked for recovery, moisture and contamination. |

| Criteria | JORC Code Explanation | Explanation |
|---|---|---|
| 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. The crusher and pulveriser are flushed with barren material at the start of every batch. |

| Criteria | JORC Code Explanation | Explanation |
|---|---|---|
| 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. 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. 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 |

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 |

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 ≥ 0.5g/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 0.5 g/t Au cut-off calculations, up to 3m (down hole) of internal waste, unless the total intercept grade falls below 0.5 g/t gold. |
Page | 17
==> picture [595 x 85] intentionally omitted <==
| Criteria | JORC Code explanation | Explanation |
|---|---|---|
| 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. |
|
| 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. |
