Australian Securities Exchange Announcement | 7/8/2020 |
------------------------------------------------------------------------------------------------------------
King River Resources Ltd (ASX:KRR) is pleased to announce a 2,000m RC drill programme will commence on Monday 10 August 2020, testing for high-grade gold mineralization at its Tennant Creek project, after delays caused by the Covid 19 pandemic restrictions.
The drilling will follow-up on very encouraging geophysical results returned from 2019 geophysical surveys (ground magnetics and gravity) shown in Figures 1 and 2 (see KRR ASX announcements 10/1/20 and 16/7/20). KRR will also commence reconnaissance exploration and geophysical surveys (ground and airborne) in the coming weeks to progress other priority targets for drilling.
Drill Programme Commencing - EL31619
Drilling at the Lone Star area will target 3 main coincident gravity and magnetic trends. The strength of the magnetic and gravity anomalism of these targets is comparable to other known Iron Oxide Copper Gold (IOCG) deposits in the area. Of note Emmerson Resources Mauretania deposit is only 700m from the western boundary of KRR's tenement where 20m @ 38.5g/t Au was returned in a diamond drill hole last year (Emmerson Resources ASX announcement 4/7/19). This and other nearby deposits follow NW-SE and EW trends that can be seen in the geophysical results.

Drilling will then move to the Commitment Prospect where a large coincident magnetic and gravity anomaly follows a NW/SE trend. Drilling will target the main magnetic body as well as a strong gravity anomaly slightly offset from the main magnetic body possibly representing a hematite rich zone.

Other Tennant Creek Exploration Plans
The company's wholly owned subsidiary Treasure Creek Pty Ltd holds 7,900km2 in 16 tenements (14 granted and 2 applications) in the Tennant Creek Region around the Tennant Creek, Rover and Kurundi Gold fields, covering 4 main project areas: Tennant Creek East, Tennant East/Barkley, Rover East and Kurundi (Figure 3, Table 1).

The Tennant Creek and Rover gold fields are host to high-grade IOCG deposits with over 5.5M ozs Au mined from Tennant Creek and a resource of 1.2M oz Au estimated in 2010 at Rover 1 (Westgold Resources 23/2/10 ASX release). The Treasure Creek holdings cover areas along strike of both the Tennant Creek and Rover Gold Fields areas of similar stratigraphic and structural settings. Past exploration in these areas has been brief, sporadic and disjointed, with many areas under shallow Cambrian cover preventing discovery by historic explorers. The company believes that, with the application of systematic exploration and new/advanced geophysical techniques, significant gold discovery could be made.
Exploration is targeting IOCG style mineralization (IOCG) characterized by gold and copper mineralization associated with ironstone bodies, likely of the Tennant Creek Style. These ironstone bodies have varying degrees of hematite and magnetite often forming discrete geophysical targets and may be characterised by the bonanza gold intersections seen elsewhere at Tennant Creek.
`
In addition to the current drill programme, exploration planned for 2020 will also include reconnaissance of the Tennant Creek East area which is immediately adjacent to the Metallic Hill, Blue Moon, Lady May, and Gigantic historic IOCG gold mines (all between 200-800m of the tenement boundary). The best of the known magnetic anomalies and reconnaissance discoveries in this area will be tested with ground magnetics/gravity surveys this year.
In the Tennant East/Barkley area KRR has been awarded a grant for funding under Round 13 of the Geophysics and Drilling collaborations program administered by the Northern Territory Geological Survey (NTGS). The co-funded programme (50% of survey costs) includes a ground geophysical and a detailed airborne magnetics survey over EL31633 and a ground geophysical survey over EL31634 to test and define significant magnetic anomalies and depth of cover in a previously unexplored area.
Initial reconnaissance exploration is also planned for KRR's Kurundi Project where KRR has 4 exploration licences (2 granted) over part of the Kurundi Anticline and covers the Kurundi historic gold mine (historic underground and open pit mining where previous exploration rock chip sampling returned gold results over 5g/t Au and copper values up to 9.7% Cu) and the Whistle Duck prospect where previous exploration reported gold results up to 13g/t Au and copper values up to 5% Cu in rock chip sampling.
Proposed 2020 exploration at Tennant Creek is summarized below:
- RC drill programme at Lonestar Trend, Commitment and BIF Hill.
- Reconnaissance exploration of Tennant Creek East.
- Ground magnetic surveys at Tennant Creek East best air magnetics and reconnaissance anomalies.
- Airborne magnetics and ground geophysical surveys at Tennant East/Barkley -EL31633 and EL31634.
- Reconnaissance exploration at Kurundi.
- Follow-updrilling of best results from 2020 exploration.

RC Sampling: All samples from the RC drilling are taken as 1m samples. Samples are sent to | |||
ALS Laboratories in Perth for assaying. | |||
Appropriate QAQC samples (standards, blanks and duplicates) are inserted into the sequences | |||
as per industry best practice. Samples are collected using cone or riffle splitter. Geological | |||
logging of RC chips is completed at site with representative chips being stored in drill chip trays. | |||
Onsite XRF analysis is conducted on the fines from RC chips using a hand‐held Niton XRF | |||
Model XL3T 950 Analyser. These results are only used for onsite interpretation and preliminary | |||
assessment subject to final geochemical analysis by laboratory assays. Actual values are not | |||
quoted and the results are used as an interpretive tool for further drill hole design. Detection of | |||
gold by the Niton device is not considered reliable as it is possible that a mineral with similar | |||
characteristics was detected. | |||

Planned RC Programme | |||
No new drilling reported. | |||
The RC drilling rig has a cone splitter built into the cyclone on the rig. Samples are taken on a | |||
one meter basis and collected directly from the splitter into uniquely numbered calico bags. The | |||
Criteria | JORC Code explanation | Commentary |
calico bag contains a representative sample from the drill return for that metre. This results in a | ||
representative sample being taken from drill return, for that metre of drilling. The remaining | ||
majority of the sample return for that metre is collected and stored in a green plastic bag marked | ||
with that specific metre interval. The cyclone is blown through with compressed air after each | ||
plastic and calico sample bag is removed. If wet sample or clays are encountered, then the | ||
cyclone is opened and cleaned manually and with the aid of a compressed air gun. | ||
Geological logging of RC chips is completed at site with representative chips being stored in drill | ||
chip trays. Downhole surveys of dip and azimuth are conducted using a single shot camera every | ||
50m to 100m to detect deviations of the hole from the planned dip and azimuth (every 10m for | ||
close spaced infill drilling. The drill‐hole collar locations were recorded using a hand held GPS, | ||
which has an accuracy of +/‐ 10m. At a later date the drillhole collar may be surveyed with a | ||
