Adavale geochem results confirm elevated nickel and copper at Tanzanian project

Adavale Resources Limited - Adavale geochem results confirm elevated nickel and copper at Tanzanian project
Kabanga Jirani Nickel Project in Tanzania’s northwest is touted as a potentially large project.

Adavale Resources Limited’s (ASX:ADD) initial exploration carried out in the last six weeks of 2020 has led to confirmation of several high priority targets at the Kabanga Jirani Project in Tanzania.

These targets were identified by elevated nickel and copper readings coincident with magnetic lows and/or EM anomalies.

The objective of Adavale’s Tanzanian exploration programs is to find an analogue to the nearby world-class Kabanga Nickel Deposit.

Preliminary exploration techniques being utilised by Adavale allow for the identification of features displayed by the Kabanga deposit, notably:

  • Elevated nickel and copper in soil samples;
  • A conductive electromagnetic response resulting from massive sulphides; and
  • Magnetic lows typical of underlying ultramafic host rocks within the Kibaran Belt.

According to the company, the latest work program that started last month is adding the levels of detail necessary for identifying this kind of mineralisation.

Adavale intends to use this for the design and sequence of a maiden drilling program.

“In line with expectations”

Adavale CEO Allan Ritchie said: “We are delighted that early results are in line with our expectations and validate the vectors and process we are using for the design of our drill targets.

“We are eager to mobilise the rigs and get holes in the ground but the current work being conducted is methodical, very cost-effective and providing meaningful data.

“Given that, we will push to complete the current program asap so that we have the highest possible level of confidence that the targets we have selected will deliver meaningful intercepts when drilling commences during Q2.”

Previous program

Work in late 2020 began with a relatively broad spaced sampling program, with a line spacing of 1-kilometre and a station spacing of 500 metres.

The objective of the program was to see if geochemical signatures could be obtained that may indicate the presence of underlying ultramafic rocks and to determine how well that data corresponds to favourable geophysical features.

Next steps

Target areas are being followed up with infill soil sampling to be conducted on a 400-500 metre line spacing and 50-metre station spacing.

This station spacing is considered appropriate to identify the potentially small footprint of an ultramafic chonolith given that ideally any feature of interest is sampled multiple times.

The option of conducting a regional Anisotropic Magnetic Susceptibility (AMT) survey is being investigated to be implemented at the same time as the infill soil sampling ahead of ground EM.

Due to the significant number of drilling targets expected to be generated, Adavale’s strategy is to select one tenement for its first drilling campaign, while AMT and ground EM continues on other tenements.

The company is arranging the ground EM consultant and preparing the drilling contract tender document.
