These latest drillingresults provide further encouragement on Jervois’ Ugandanexploration properties. The highly anomalous results achieved todate continue to expand the prospective areas and improve theunderstanding of the mineralization present.
Drill site reclamation and rehabilitation wasimmediately carried out in accordance with the terms of the ESIAcertificate from NEMA and international good practice.
Throughout the recent drilling program, Jervois’stringent Covid-19 management measures enabled ongoing and positivealbeit modified engagement with communities within the drill programarea and local and central government. Throughout the duration of theprogram, no cases of covid-19 were obtained throughout regular PCRtesting of Jervois personnel, contractors and local service providersand the situation provided an opportunity to build local understandingof both the project and measures to prevent the spread of thevirus.
All exploration activities in Uganda have beensuspended due to a combination of ongoing Covid-19 risks, politicaland regulatory developments in-country and results to date outside theKilembe Area Properties which do not meet mineralization modelexpectations for copper-cobalt ore deposits. Jervois is initiating apartnering process for its Ugandan exploration portfolio and thecurrent book value (A$20.5 million) will be subject to carefulimpairment review as part of the December 2020 annual accountpreparation.
Jervois continues to maintain a footprint and executivepresence in Uganda, as it continues to negotiate with governmentregarding its interests in the Kilembe copper-cobalt mine and KaseseCobalt refinery.
All rock and soil samples aresent to ALS Chemex South Africa (Pty) Ltd, an independent and fullyaccredited laboratory in South Africa for analysis for goldmulti-element Induction Coupled Plasma Spectroscopy. Jervois alsohas a regimented Quality Assurance, Quality Control program where atleast 10% duplicates and blanks are inserted into each sampleshipment.

JORC Code, 2012 Edition– Table 1
Section 1 SamplingTechniques and Data
Criteria | JORC Code explanation | Commentary |
Sampling techniques |
| Sampling to date includes 5,138 diamond drill samples(from 59 diamond core drill holes); 23,142 soil samples; 3,625 rocksamples, 26 Heavy Mineral Concentrates; 25 stream silt samples; 1,258trench samples (rock); and, 379 trench samples (soil). All drill core was generally sampled on 1m intervals,contingent on geology and core recovery: Core was collected directly from the core barrel intocore boxes, and Core samples were split in half, with the top half ofthe core analysed and other half retained as reference core in thetray. Core trays were clearly labelled with the hole number, traynumber and metre intervals marked. Bottom-of-hole orientation line wasmarked prior to geological logging and sampling. Soil samples (B Horizon) are collected using a pick andspade to dig small pits which are filled back in after the sample iscollected. The samples are collected in 4x6’ kraft bags andclosed/sealed with a zip tie. All sample information is recorded onhand-held devices utilizing the Fulcrum App. ALS Sample tag booksare utilized for sample identifiers which are scanned and/or enteredmanually. The sample identifier is written on the bag and a tag isplaced in the bag. Sample and site photos are recorded at everysite. Devices are downloaded daily are all information is stored tothe cloud. Rock samples (typically grab samples) are collectedusing a rock hammer. The samples are selective and are notnecessarily indicative of mineralization. The samples are collectedin 12x20 plastic ore bags and closed/sealed with a zip tie. Allsample information is recorded on hand-held devices utilizing theFulcrum App. ALS Sample tag books are utilized for sampleidentifiers which are scanned and/or entered manually. The sampleidentifier is written on the bag and a tag is placed in the bag. Sample and site photos are recorded at every site. Devices aredownloaded daily are all information is stored to the cloud. Samples were cut along the orientation line beforebeing correctly placed back into the tray. The half-core was sampled,ensuring that the same side is consistently sampled, and placed intosample bags labelled with the assigned sample number. Orientationlines are determined using a Reflex ACTIII orientation tool. Downhole measurements are recorded using a Reflex EZ-Gyro Kit at multiple intervals down each hole andalways at the end of every hole. Field sampling followed Jervois protocols includingindustry standard quality control procedures. All samples were sent to ALSChemex South Africa (Pty) Ltd., an independent and fully accreditedlaboratory in South Africa (“ALS”) foranalysis for gold multi-element Induction Coupled Plasma Spectroscopy(“ICP”). Jervois also has a regimented Quality Assurance,Quality Control (“QA/QC”) programme where at least 10% duplicatesand blanks are inserted into each sample shipment. Sample representativity is ensured by: Diamond Core: For all drilling core was halved for sub?sampling with a diamond saw. Sample intervals range from 0.1 to 2 m in length, with majority ofsamples assayed over 1 m intervals. Rock grab samples are by theirnature selective and are not necessarily indicative of the generalgeology of the property. Handheld XRF instruments were used to spot check rockgrab and/or drill core for mineralization, however those results werenot relied on. All sample results reported on are from ALS Chemex South Africa (Pty) Ltd. Some Drill holes were lined with PVC piping and in most holes,downhole Electromagnetics were completed after drilling was complete. All of the drilling was diamond drill core (HQ/NQ). Typically, drill core was sampled on nominal 1m half core samples. All sample analyses were completed at ALS Chemex SouthAfrica (Pty) Ltd. and/or ALS Chemex Vancouver, Canada. ALS is aglobal independent laboratory which is ISO accredited. Samples are received at the laboratory: Bar codes arescanned and logged; samples are weighed and dried; samples are crushedand pulverized (-180 mesh soils; -75microns rocks) then riffle split;all samples are analyzed for 35 elements using ICP-AES and gold using30 gram fire assay for soils and 50 gram Fire assay for rocks, bothwith an AA finish. Any samples with over-limits specific to basemetals or gold are re-analyzed. Samples with visible gold were checkanalysed by using a screen fire-assay method. |
Drilling techniques |
| HQ casing/coring within saprolite yet the majority ofthe core was NQ Holes were generally angled from 45 to 90 degrees atvarying azimuths. Reflex Orientation tool was used for structuralorientations, and depths varied from 8.85m to 418.8m. |
Drill sample recovery |
| All holes are teched and all intervals are measured forrecovery and RQD’s are calculated. Recovery % recorded in thegeotechnical records as equivalent to the length of core recovered, asa percentage of the drill run. Excellent recoveries were obtained from Diamonddrilling. There is no bias noted between sample recovery andgrade. Excellent recoveries were obtained from Diamonddrilling. |
Logging |
| Diamond drilling: Drill core is photographed and logged prior to sampling; Core has been geologically and geotechnically logged toa level of detail appropriate to support mineralresource estimation and mining studies. Logging has been conducted both qualitatively andquantitatively; full description of lithologies, alteration andcomments are noted, as well as percentage estimates on veining andsulphides. In total, 10,078m of diamond drill core have beencompleted. All drill holes are logged in their entirety. |
Sub-sampling techniques and sample preparation |
For all sample types, the nature, quality andappropriateness of the sample preparation technique.
| Core was half-cut lengthwise using a diamond saw alongthe orientation line. The half-core was sampled, generally on metreintervals. Samples are received at the laboratory: Bar codes arescanned and logged; samples are weighed and dried; samples are crushedand pulverized (-75microns rocks) then riffle split; all samples areanalyzed for 35 elements using ICP-AES and gold using 50 gram Fireassay with an AA finish. Any samples with over-limits specific tobase metals or gold are re-analyzed. For core sampling the same side is consistentlysampled, half-core with the bottom of hole line is retained in thetray. The assay sub- sample is placed into sample bags labelled withthe assigned sample number. One in 20 samples is duplicated where the core isquartered and a quarter cut sample is analysed as a duplicate. Theremaining quarter samples is retained in the tray. Sample sizes of 2-3 kg are appropriate for the grainsize of material. The sample preparation technique and sample sizesare considered appropriate to the material beingsampled. |
Quality of assay data and laboratory tests |
| The ICP-AES and Fire Assay (50 gram) are consideredtotal and are high quality. Jervois has a regimented Quality Control protocol whichhas consisted of systematic submission of blanks and duplicates inaddition to those conducted at the laboratory. Precision levels for all blank and duplicate samplesfell within acceptable ranges. |
Verification of sampling and assaying |
| Since no economic intersections have been reported,independent verification has not yet been necessary. No holes have been twinned. Data is collected using a customized version of theFulcrum app. The data is backed up systematically on and off site aswell as on the cloud. As well, data is recorded using a masterMicrosoft Office Excel spreadsheet and all location and assay data arecompiled in a Microsoft Office Access database. All data below detection limit have been entered aszero. Samples received damaged at the laboratory, or withinsufficient sample weight for analysis had the interval or locationleft blank, but in general were re-sampled and/or re-collected(specific to soils and rock grab samples). |
Location of data points |
| All collars were surveyed by trained surveyors using aLeica Differential GPS. Down-hole surveys were routinely carried outon all holes using a Reflex EZ-Gyro Kit. Trenches and surfacesamples were recorded using handheld GPS. All datum is collected and recorded in UTM WGS1984. The 3D location of the individual samples is consideredto be adequately established, consistent with accepted industrystandards. Locations are shown on maps provided. Cross sectionsand a complete table of results are only reported when targetmineralization was intercepted with the consistency of width and gradenecessary to support a potentially economic resource |
Data spacing and distribution |
Whether the data spacing and distribution is sufficientto establish the degree of geological and grade continuity appropriatefor the Mineral Resource and Ore Reserve estimation procedure(s) andclassifications applied.
| To date, due to the exploratory nature of the drilling,the spacing is highly variable. Similarly, rock grab sample spacingis random. Soil samples are collected in grids designed at varyingspacings from >350m to 25m spaced samples. Samples intervals are reported as weighted averagegrade. |
Orientation of data in relation to geologicalstructure |
| Drilling sections are orientated perpendicular to thestrike of the host rocks. Drill holes wereinclined between 45° and 90° to optimize intercepts ofmineralisation with respect to thickness and distribution. Drilling with angled and vertical holes in mostinstances provides a representative sample across thestratigraphy. |
Sample security |
| All individual samples are bagged and sealed with a ziptie. Then individual samples are bagged in poly woven sacks andsealed with coded security seals. The laboratory reports all thesecurity seals numbers to Jervois and any problems with the samples. To date, no sample shipments have had reported problems and/or abreach in security. |
Audits or reviews |
| Jervois protocols consist of a regimented internalQA/QC which match or exceed global industry standards. Thus far, dueto the exploratory nature of the programme, no audits or externalreviews have been conducted. |
