GRDD040 - 400.8m @ 0.57g/t Au from surface including 95.88m @ 1.24g/t Au from 220m GRDD041 - 468m @ 0.43g/t Au from surface
PERTH, AUSTRALIA / ACCESSWIRE / August 8, 2022 / Amani Gold Limited (ASX:ANL), (OTC PINK:BRYYF) ("Amani" or "the Company") is pleased to announce assay results for three diamond drill holes completed at the Company's 4.1Moz Kebigada deposit.
Drilling was intended to target high grade gold mineralization within the existing resource area and depth extensions of the Kebigada central and eastern ore bodies.
GRDD040 and GRDD041 returned a very broad intersections of 400.80m @ 0.57g/t Au from surface (228 gram meters ) and 468m @ 0.43g/t Au from surface (200 gram meters ) respectively. These two holes confirm the broad and consistent gold mineralization in the Kebigada eastern ore body.
Assays results were returned for the final 146.67m of GRDD039, significant intercepts are listed in Table 2.
On the Drill Results, Amani Chief Executive Officer Conrad Karageorge commented:
"We are very excited about the latest results from our 2022 drilling campaign.
Holes GRDD040 and GRDD041 have each returned over 400m of mineralization, confirming the grade and consistency of the Kebigada eastern ore body.
These latest results further highlight the potential for Kebigada to become a world class gold project."

The Giro Gold Project comprises two exploration permits covering a surface area of 497km² and lies within the Kilo-Moto Belt of the DRC, a significant under-explored greenstone belt which hosts Randgold Resources' 17 million-ounce Kibali group of deposits within 35km of Giro. The nearby Kibali Gold Project produces more than 600,000oz gold per annum.
The Giro Gold Project area is underlain by highly prospective volcano-sedimentary lithologies in a similar structural and lithological setting as the Kibali gold deposits. Both primary and alluvial gold was mined from two main areas, the Giro and Tora areas, during Belgian rule and today. Giro Gold Project global resource for Kebigada and Douze Match deposits exceeds 4.4Moz contained gold; with a total Indicated and Inferred Mineral Resource Estimate of 132Mt @ 1.04g/t Au, for 4.4Moz gold (0.5g/t Au cut-off grade). The Kebigada resource followed diamond core drilling results which successfully targeted deeper high-grade sulphide associated gold mineralisation within the central core of the Kebigada deposit. Drillholes GRDD034 and GRDD035 are 240m apart and both outlined high-grade gold mineralisation deeper than previously intersected at the Kebigada deposit. These gold assay results and the current Kebigada MRE indicate the potential for the Kebigada deposit to substantially grow via targeted deeper drilling along the entire strike of the orebody.

Diamond Core Drilling - Kebigada
Sampling of diamond core was carried out under strict QAQC procedures as per industry standards where certified reference materials (CRMs) of varying grades, blank samples and field duplicates are each inserted at a rate of 1 in 30 so that every 10th sample is a quality control sample. Sampling was carried out according to lithological/structural boundaries having a minimum sample width of 40cm and a maximum sample width of 2m. HQ and NQ samples were split with the same half consistently submitted for assay. The samples which had an average weight of approximately 2-3kg were then crushed and split in an accredited laboratory to produce a 50g charge for fire assay with AA finish.
Diamond Core Drilling - Kebigada
HQ core drilling down to fresh rock after which the hole was cased off before changing to NQ. Standard core barrels were used throughout the drilling campaign. The holes were orientated with a compass, and surveyed at 30 m intervals using a Reflex EZ-Trac instrument. Solid drill core was orientated using a Reflex Act III core orientation tool.
Diamond Core Drilling - Kebigada
All core is fitted and measured at the drill site and core gains or recoveries recorded against the driller's depths. Sample recovery was recorded in the drill logs, as well as sample loss. Core recoveries were generally better than 80% in the weathered zone and greater than 95% in the intermediate and fresh profile. Where losses were noted in the saprolitic interval, sample widths were limited to the width of the run with a maximum of 1.5m which was the length of the core barrel. As poor recovery affected a minority of the samples, it was not taken into account while calculating mineralised intervals.
Diamond Core Drilling - Kebigada
All core was logged geologically, geotechnically and structurally at industry standard levels. Core is marked with metre marks every metre and orientation and cut lines marked on every hole according to a fixed procedure. Logging is both qualitative and quantitative with core photographed for both wet and dry sample before being split. The total length of all drill holes was logged recording lithology, alteration, weathering, colour, grain size, strength, mineralisation and quartz veining.
Diamond Core Drilling - Kebigada
The highly weathered saprolitic zone was split using a bladed instrument. As soon as core had sufficient strength to withstand cutting using a diamond saw the cutting method was changed to the latter. All core was halved with the same half selected for sampling according to procedure. Sampling was then conducted according to geology or structure generally having a maximum sample width of 1m for HQ core and 2m for NQ. Half core samples were then bagged in clear plastic bags with pre-printed sample tickets. Sampling was carried out under strict QAQC procedures as per industry standards where certified reference materials (CRMs) of varying grades, blank samples and field duplicates are each inserted at a rate of 1 in 30 so that every 10th sample is a quality control sample. The sample bags containing approximately 2-3kg of diamond core sample were sent to the SGS (African Assay Laboratories) in Tanzania.
The final sample was crushed to >75% of the sample passing as less than 2mm. 1.5kg of sample was split from the crushed sample and pulverized until 85% of the material could pass a 75um sieve. From this, a 50g sample was selected for fire assay at the SGS Laboratory.
Crushing and pulverising were subject to regular quality control practices of the laboratory.
Sample sizes are appropriate considering the grain size of the samples. However, in the case of lateritic lithology, a nugget effect is likely to occur. Intervals in laterites will therefore be treated separately in any resource estimations.
Diamond Core Drilling - Kebigada
The laboratory used 50g of sample and analysed samples using Fire Assay with an AA finish. This technique is considered an appropriate method to evaluate total gold content of the samples. In addition to the laboratory's internal QC procedure, every 10th field sample comprised a blank sample or standard sample.
The interval of core samples of hole GRDD039 (151 samples) contained 6 blanks and 5 standards whose results showed excellent accuracy. Furthermore, 6 duplicates were analysed and showed good precision.
The interval of core samples of hole GRDD040 (408 samples) contained 15 blanks and 15 standards whose results showed excellent accuracy. Furthermore, 15 duplicates were analysed and showed good precision.
The interval of core samples of hole GRDD041 (480 samples) contained 18 blanks and 18 standards whose results showed excellent accuracy. Furthermore, 17 duplicates were analysed and showed good precision.
Diamond Core Drilling - Kebigada
Logging and sampling data was entered into spreadsheets, then checked by the Exploration Manager for inconsistencies and stored in an Access database.
Holes are logged by hand on printed log sheets. Logging is done according to standardised header, lithological and structural information. Data is then input into EXCEL spread sheets which are then emailed to the database manager for input into Access. Data is then interrogated and all discrepancies are communicated and resolved with field teams to ensure only properly verified data is stored in the Access database.
Drill hole collars were recorded using a Garmin handheld GPS with an error margin of less than 5m. Hole positions are marked using tape and compass reducing relative error to less than 1metre along each drill line. The holes are surveyed using a DGPS with centimetre accuracy. Coordinates are reported in the WGS84-UTM35N Grid system.
Diamond Core Drilling - Kebigada
The diamond drilling program is designed to delineate the down-dip extensions of the mineralised zones.
Diamond Core Drilling - Kebigada
Drillholes were oriented perpendicularly to the interpreted strike of the mineralised zone already drill delineated by the previous drilling.
Samples were collected under strict supervision of the Senior Exploration Geologist. Bagged samples were then labelled and sealed and stored on site in a locked dwelling for transport to the laboratory. Samples were transported to the laboratory in a sealed vehicle under supervision of a contracted logistics company.
The Competent Person for the Exploration Results has not visited the site due to Covid-19 travel restrictions. However, the Competent Person has reviewed all of the historical QAQC data and checked assays with the original laboratory reports and is satisfied that the exploration work has been carried out in a satisfactory manner.
The project comprises two Exploitation Permits (Permisd'Exploitation), PE5046 and PE5049.These are owned by a joint venture company, Giro Goldfields Sarl, formed between Amani Consulting Sarl (65%) and Société Minière de Kilo-Moto SA (SOKIMO) (35%), both DRC registered entities. Amani Gold holds 85% of Amani Consulting. Tenure is in good standing.
The licensed area has not been systematically explored since the end of Belgian colonial rule in 1960. Two field visits were conducted in the area, the first in 2010 by the "Office des Mines d'Or de Kilo-Moto" (OKIMO), and the second in December 2011 by Universal Consulting SPRL, working for Amani Consulting.
Following a review of historical and previous exploration data, Panex Resources Inc. conducted a first RC drilling campaign at the Giro prospect between December 2013 and February 2014, completing 57 holes for 2,888m.
The geological setting is comprised mostly of volcano-sedimentary rocks from the Kibalian complex, with multiple granites and granitoid intrusions. A network of faults seems to have been reactivated at different intervals.
At the Giro Gold Project, the main lithologies hosting the mineralisation are saprolite, quartz veins and stringers and silicified volcano-sediments. Mineralisation is associated with quartz veining and silicification of host rocks along a major NW trending shear zone. Generally, higher gold grades are associated with greater percentages of sulphide (pyrite) and silicification.
Drill hole collar data and main intervals are shown in Table 1.
Elevation data was recorded using a Garmin handheld GPS. Once the programme is completed all drill hole collars will be surveyed with a DGPS to accurately establish position and elevation.
Diamond Core Drilling - Kebigada
Each sample generally represented 1m of diamond drilling however lithological and structural contacts are taken in consideration and intervals adjusted accordingly.
The intersections reported were weighted by length to calculate the mean grades over sample intervals.
Diamond Core Drilling - Kebigada
The drill holes were drilled with dips of -55°.
Drilling has indicated that the drill holes were drilled normal to the foliation but structural logging suggests mineralisation is associated with multiple structural orientations which makes it difficult to ascertain the true structural orientation controlling mineralisation.
True widths could not be determined as dip of mineralisation is still not clear with limited overlap in drill holes but is estimated to be 50-60% when using the dip of the regional foliation.
Table 1 shows the drill collar positions, Figure 2 shows a cross section with reported results. All mineralised intervals are reported in Table 6.
Drill holes drilled in the completed program are shown in Table 1 and all the results received for Kebigada which are reported in Table 6, according to the data aggregation method described previously. All high grade intercepts are reported as included intervals in Table 2.
Kebigada results are being assessed on an ongoing basis and additional holes planned and drilled when deemed necessary. A number of significant soil anomalies in the immediate vicinity of the main Kebigada ore body will be tested with shallow RC drilling.
