DRILLING CONFIRMS POTENTIAL FOR SATELLITE DEPOSIT AT LIVINGSTONIA
Lotus Resources Limited ( ASX: LOT, OTCQB: LTSRF ) ( Lotus or the Company ) is pleased to announce the results of the reverse circulation ( RC ) drilling program at its Livingstonia prospect, located approximately 90km from the Kayelekera uranium mine ( Kayelekera or the Project ) in Malawi. Whilst not part of the current Definitive Feasibility Study ( DFS ), Livingstonia has the potential to become a satellite deposit in the future.
HIGHLIGHTS
-
A 29-hole (3,395 metre) RC drill program has been completed at the Livingstonia prospect, located 90km from the Kayelekera uranium mine
-
The program was designed to convert the historic U3O8 Mineral Resource estimate (JORC 2004) into a JORC 2012 compliant Mineral Resource and to test potential extensions
Results include:
-
3m at 733 ppm U3O8 from 94m (LIV003)
-
4m at 983ppm U3O8 from 87m (LIV007)
-
4m at 636ppm U3O8 from 74m (LIV011)
-
6m at 379ppm U3O8 from 89m (LIV005)
-
Drilling expanded mineralisation by up to 250 metres north of the existing resource limits
-
An updated Mineral Resource estimate for Livingstonia is anticipated for release later this quarter
Keith Bowes, Managing Director of Lotus, commented:
“The acquisition of the Livingstonia prospect last year consolidated the Company’s ownership of our southern project area, a known uranium mineralised district that has had very limited exploration work completed over the years.
The strategy at Livingstonia has been to complete a small drilling program to confirm historical results and test extensions around the known mineralised area in order to enable preparation of a JORC (2012) compliant Mineral Resource estimate. We believe the drilling has been successful and an updated Mineral Resource estimate is now planned for completion in the June quarter.
Whilst Livingstonia is not included in the current Definitive Feasibility Study, we believe there is potential for it to become a satellite operation in the future once the Kayelekera resource has been depleted, especially if similar success with ore sorting can be achieved.”

LIVINGSTONIA RC DRILLING PROGRAM
The Livingstonia exploration tenements are located in northern Malawi, approximately 90km southeast of the Company’s Kayelekera uranium mine (Figure 1). Combined with the Company’s Chilumba tenements, this region covers 300km[2] .

Figure 1: Lotus Tenement Areas
In December 2021, Lotus commenced its inaugural uranium exploration drill program at Livingstonia. The program consisted of 3,395 metres in 29 vertical RC drill holes, targeting areas both within and peripheral to the existing Mineral Resource to test the margins of the resource estimate for further extensions.
==> picture [505 x 63] intentionally omitted <==
==> picture [468 x 64] intentionally omitted <==
The drilling was caried out by Thompson Drilling Lda (Mozambique) with downhole radiometric (gamma) logging undertaken by experienced local contractors under the supervision of Lotus geologists.
All downhole gamma data is tabled in Appendix 1. Selected mineralised intervals were analysed for uranium by ALS Laboratories in Johannesburg (Table 1).
The focus of the RC program was on the northern margins and north-eastern extensions of the known mineralised trend. The holes completed in these locations were designed to either define extensional mineralisation or increase the confidence in the existing resource classification (Figure 2).
The best results of 4m grading 983 ppm U3O8 and 4m grading 636ppm U3O8 are located to the north of the existing resource limits and extend the previous resource limits by up to 250m.
Several holes were completed within the existing resource limits in order to validate the historic resource. Following these results, the Company intends to prepare an updated Mineral Resource estimate, which is anticipated to be completed during 2Q2022.

ABOUT LOTUS
Lotus Resources Limited (ASX: LOT, OTCQB: LTSRF) owns an 85% interest in the Kayelekera Uranium Project in Malawi. The Project hosts a current resource of 46.3Mlbs U3O8 (see table below), and historically produced ~11MIb of uranium between 2009 and 2014. The Company completed a positive Restart Study[1] which demonstrated that Kayelekera can support a viable long-term operation and has the potential to be one of the first uranium projects to recommence production.
