TheNewswire - January 26th, 2021 - Jervois Mining Ltd. (the "Company" or "Jervois") (ASX:JRV) (TSXV:JRV) (OTC:JRVMF) is providing an update on drill programme at its Kilembe area properties in central and western Uganda, following receipt of assays from Q4 2020 exploration.
Drilling at the Kilembe Area Properties targeted surficial Au-Cu mineralization detected through earlier geochemical programmes. In total, 1,905 metres of diamond drilling was completed in 17 holes drilled at the Kilembe Area Properties in 2019 and 10 holes in 2020, totaling 1,409m. The drill hole locations for drilling at the CC Target in Q4 2020 are shown on Figure 1 and the drilling result highlights are in Table 1.

* As this is an initial drilling programme true widths are currently unknown.
These latest drilling results provide further encouragement on Jervois' Ugandan exploration properties. The highly anomalous results achieved to date continue to expand the prospective areas and improve the understanding of the mineralization present.
Drill site reclamation and rehabilitation was immediately carried out in accordance with the terms of the ESIA certificate from NEMA and international good practice.
Throughout the recent drilling program, Jervois' stringent Covid-19 management measures enabled ongoing and positive albeit modified engagement with communities within the drill program area and local and central government. Throughout the duration of the program, no cases of covid-19 were obtained throughout regular PCR testing of Jervois personnel, contractors and local service providers and the situation provided an opportunity to build local understanding of both the project and measures to prevent the spread of the virus.
All exploration activities in Uganda have been suspended due to a combination of ongoing Covid-19 risks, political and regulatory developments in-country and results to date outside the Kilembe Area Properties which do not meet mineralization model expectations for copper-cobalt ore deposits. Jervois is initiating a partnering process for its Ugandan exploration portfolio and the current book value (A$20.5 million) will be subject to careful impairment review as part of the December 2020 annual account preparation.
Jervois continues to maintain a footprint and executive presence in Uganda, as it continues to negotiate with government regarding its interests in the Kilembe copper-cobalt mine and Kasese Cobalt refinery.
Quality Assurance
All rock and soil samples are sent to ALS Chemex South Africa (Pty) Ltd, an independent and fully accredited laboratory in South Africa for analysis for gold multi-element Induction Coupled Plasma Spectroscopy. Jervois also has a regimented Quality Assurance, Quality Control program where at least 10% duplicates and blanks are inserted into each sample shipment.

These examples should not be taken as limiting thebroad meaning of sampling. |Sampling to date includes 5,138 diamonddrill samples (from 59 diamond core drill holes); 23,142 soil samples;3,625 rock samples, 26 Heavy Mineral Concentrates; 25 stream siltsamples; 1,258 trench 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.

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.
