Delta, British Columbia, August 29, 2022 Desert Gold Ventures Inc. (the “Company”) (TSX.V: DAU, FSE: QXR2, OTCQB: DAUGF) announces preliminary metallurgical results from the first RC/core holes by the Company at its Mogoyafara South, Linnguekoto West and new Gourbassi West North Zones (see Figure 1 for locations). Mineralized intervals of fresh rock, generally from a single lens (except at Mogoyafara South where two lenses were sampled) from each of these zones were subjected to 72-hour bottle roll analysis. The Company carries out this routine metallurgical analysis as soon as fresh rock samples are available from any potential or existing mineral resource targets. Composite samples are created by combining assay rejects from a mineralized interval. These rejects are then ground to 80% passing 75um with approximately 1.5 kg of sample mixed with a CN-bearing solution held at a PH of approximately 10 with timed extraction of the assay liquor at 12, 24, 36, 48 and 72 hours. The samples and CN-bearing fluids are slowly rolled to ensure continuous mixing of sample pulps and CN-bearing solutions. Fire assays of the pulped composite sample are taken both at the beginning and the end of the 72-hour time bottle roll leach period.
Samples from Mogoyafara South, returned good, best, fresh rock recoveries of 86% and 88%. Two samples from Gourbassi West North and one from Linngukoto West returned poor bottle-roll leach recoveries ranging from 22% to 25%. Additional metallurgical tests comprising finer grinding and the addition of reagents will be carried out on all of the samples to determine if first pass metallurgical recoveries can be easily improved. As well, metallurgical samples from other mineralized lenses and the oxide portions of these zones will be subjected to first pass metallurgical testing. Initial and final assay’s variability are expected to be related to variability within a sample pulp verses the result of variability due to coarse gold.
A summary of the metallurgical test work is presented in the table below.
Assay g/t Au over metres**
|% change from original assay||Recovery after 72 hrs||Best Recovery|
* MS = Mogoyafara South, LW= Lonnguekoto West, GWN= Gourbassi West North
** Estimated True width ranges from 80-90% for MS, 50% for LW and 65% for GWN
Previous Metallurgical Test work
Preliminary metallurgical test work was completed for Barani East (gold recoveries of 93.8% for oxides and 83% to 98.7% for fresh rock), Gourbassi West (gold recoveries of 93.6% for oxides and 95.2% for fresh rock) and Gourbassi East (87.6% for fresh rock) (source NI 43-101 report filed on SEDAR March 3, 2022).
*All gold grades over width, with the exception of the Soa, Berola and Gourbassi prospects, represent drill holes with the true widths, for most holes, ranging from 65 to 95%. Estimated true widths for the Soa and Berola prospects are unknown. Estimated true widths at the Gourbassi Zones are estimated to range from 60% to 90%. True widths at Linnguekoto West are estimated to be 50% of drilled length.
The Company is proposing a 35,000-metre drill program including 10,000 metres of contingency drilling. Contingency holes will have a sole purpose of developing mineral resources. Drill holes are designed to follow-up and extend known gold zones with an initial focus at Mogoyafara South and Gourbassi West North Zones and Zones area which are deemed to be the largest gold systems discovered on the property to date. Currently planned holes are presented in Figure 2.
Auger and additional AC holes to the north and east of the Gourbassi West North Zone, as well as follow-up to 2021 drill and auger results, which were not completed during the recent program, still need to be drilled. A highlight summary of the 2021 high priority targets requiring follow-up include the following:
Sola - 2.04 g/t gold over 30 metres
Kamana – 1.80 g/t gold over 17 metres
Manakoto – 1.65 g/t gold over 21 metres
Sorokoto South – 2.68 g/t gold over 6 metres
Frikidi – gold in auger values of 8,650, 3,100, 2.370, 462 and 440 ppb gold
All auger and drill samples are delivered to SGS in Bamako, Mali where they are prepped. The prepped samples, are both shipped by truck to SGS’s facility in Ouagadougou, Burkina Faso, or remain at SGS’s laboratory in Bamako, for Au determination by fire assay. Standards, assay blanks and sample duplicates, are inserted into the assay stream every 22 to 30 samples, respectively equaling one control sample for every approximately every 8 assay samples. All assay batches are reviewed for quality with re-assays requested 20 samples on either side of standards that assay more than 2 to 3 SD from an excepted value and for blanks that contain more than 10 ppb gold.
Ashanti Gold drill results QAQC Procedures for the Gourbassi East and West Zones
Certified Reference Materials and Blanks were inserted into the sample stream at the rate of 1:20 samples. Field duplicates are collected at the rate of 1:50 samples. All samples have been analyzed by SGS Laboratories in Bamako with standard preparation methods and 50g fire assay with atomic absorption finish. SGS does their own introduction of QA/QC samples into the sample stream and reports them to Ashanti for double checking. Higher grade samples are reanalyzed from pulp or reject material or both.
Hyundai QAQC Procedures
Desert Gold does not have any information regarding Hyundai’s QAQC procedures at the Linnegukoto West Zone. However, based on follow-up of historic drill results in the Barani Area indicates an acceptable level of accuracy.
