ASX RELEASE 12 March 2021 ASX: JRL
JINDALEE CONTINUES TO DEMONSTRATE
STRATEGIC SCALE OF MCDERMITT LITHIUM PROJECT
-
Assay results received for the remaining drillholes from 2020 program with all drillholes containing mineralised intervals over 1000ppm Li
-
Three of the four drillholes report significant lithium intercepts outside of current Inferred Mineral Resource[1]
-
MDRC015 expands known extents of McDermitt deposit 1.6km north and west of previous resource drilling limits
Jindalee Resources Limited ( Jindalee , the Company ) is pleased to announce assay results from the last four drillholes completed late in 2020 at the Company’s 100% owned McDermitt Lithium Project (US). The latest results continue to confirm considerable extensions to mineralisation at McDermitt with three of the holes located to the north and west of the existing Inferred Mineral Resource[1] . Highlights from these drillholes include:
-
MDRC013: 32.0m @ 1379 ppm Li from 70.2m
-
MDRC014: 70.2m @ 1221 ppm Li from 12.2m
-
24.4m @ 1887 ppm Li from 131.2m incl. 6.1m @ 2953 ppm Li
-
MDRC015: 25.9m @ 1615 ppm Li from 120.5m incl. 4.6m @ 2550 ppm Li
-
MDRC016: 15.3m @ 1554 ppm Li from 56.4m incl. 4.6m @ 2623 ppm Li
-
56.4m @ 1151 ppm Li from 122.2m incl. 4.6m @ 2150 ppm Li
MDRC014 and MDRC016 both intersected broad mineralised zones with widths exceeding 55 metres true thickness. Whilst the intersections in MDRC015 were not as broad, they are significant as the hole is located 1.6km from the nearest drillhole (MDD012) included in the 2019 Inferred Mineral Resource estimate[1] (Figure 1). As these three drillholes are located outside of the existing Inferred Mineral Resource[1] they are be expected to materially benefit the upcoming Mineral Resource update.
All drillholes completed by Jindalee to date have reported significant zones of lithium mineralisation. The 2020 drill program infill drilling has confirmed the grade and continuity of the deposit while the success of large step-outs from the current Mineral Resource, particularly in drillholes MDRC015 and MDRC004[5] , are indicative of the potential scale of the McDermitt Lithium project.

Jindalee will now engage an independent consultant to update the Mineral Resource Estimate. The increased drill density across the deposit is expected to be sufficient to extend the current Inferred Mineral Resource and Exploration Target Range[1] and convert existing Inferred Mineral Resources to Indicated status to feed into a possible Scoping Study for McDermitt in the June Quarter.
==> picture [425 x 223] intentionally omitted <==
Figure 1 – Schematic section showing recent significant intercepts through the McDermitt Project.
In addition, Jindalee is currently planning the next phase of drilling for 2021 with the aim to define the full extent of the lithium mineralisation at the McDermitt Project. This includes drilling of the remaining six holes proposed as part of the 2020 programme, which was suspended due to COVID-19 complications[2] . The drilling is planned to be a combination of Diamond Core and Reverse Circulation (RC) and will primarily focus on extensions to the west of the current deposit and continued infill drilling of the upcoming Mineral Resource (Figure 2). Applications for drill permitting will be submitted by Jindalee in April 2021.
A full summary of all drill hole data and significant intercepts received to date from the 2020 drill program is included Annexure A.
McDermitt Lithium Project – Background
In late 2019 Jindalee announced an Inferred Mineral Resource of 150Mt @ 2,000ppm Li (0.43% Li2O) at 1,750ppm Li cut-off[1] had been estimated at McDermitt (refer Table 1, below):
| Cut Off (ppm Li) |
Mass (Mt) |
Grade (ppm Li) |
Contained LCE (Mt) |
|---|---|---|---|
| 1,750 | 150 | 2,000 | 1.6 |
Table 1 – Summary of the maiden Inferred Mineral Resource
The Mineral Resource was estimated using a cut-off grade of 1,750ppm Li, which is considered appropriate in the context of similar projects and based on an assessment of the likelihood of future economic extraction as required by the JORC (2012) Code.

==> picture [559 x 74] intentionally omitted <==
The entire Inferred Mineral Resource sits within 100m of surface and is flat lying, both positive factors for future project economics. Furthermore, analysis of the grade tonnage distribution of the McDermitt resource model highlights the potential for additional material available at lower grades, and metallurgical testwork to date has been very encouraging, indicating high lithium recoveries from conventional sulphuric acid leaching at low temperature and atmospheric pressure[3.6] .
Using the same cut-off grade as the Mineral Resource, an ETR of 180-330Mt @ 1,8002,200ppm Li* (exclusive of the Inferred Resource) was also estimated[1] (refer Table 2, below).
| Cut Off (ppm Li) |
Mineral | Resource | ETR Lower Limit (Mt) |
ETR Upper Limit (Mt) |
ETR Grade Range (ppm Li) |
|---|---|---|---|---|---|
| (Mt) | (ppm Li) | ||||
| 1,000 | 996 | 1,420 | 1,200 | 3,000 | 1,200-1,600 |
| 1,500 | 328 | 1,800 | 370 | 800 | 1,600-2,000 |
| 1,750 | 155 | 2,000 | 180 | 330 | 1,800-2,200 |
| 2,000 | 64 | 2,200 | 75 | 120 | 2,000-2,400 |
| 2,500 | 5 | 2,590 | 2 | 3 | 2,400-2,800 |
Table 2 – Summary of the maiden Inferred Mineral Resource and revised ETR at various cut-off grades, with the preferred cut-off grade figures in bold. (NB: figures may not sum precisely due to rounding, and an increased number of significant figures does not imply increased precision).
*Note that the potential quantity and grade of the ETR is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource over the Exploration Target and it is uncertain if further exploration will result in the estimation of additional Mineral Resources.
2020 Drilling Program
Mid-December Jindalee announced that it had paused its drilling program at McDermitt, with 15 holes of a proposed 21 hole program completed[2] (Figure 2). All holes were vertical and were predominantly drilled using wet Reverse Circulation (RC). Samples were collected at 5 foot (1.52m) intervals and submitted to ALS (Reno, Nevada) for analysis for lithium and 47 other elements using ICP-MS.
In February 2021[5] and March 2021[7] Jindalee announced the assay results for the first 11 holes completed at McDermitt in 2020 with significant intercepts reported in every drill hole including:
-
MDRC004: 9.2m @ 2243 ppm Li from 140.3m 15.3m @ 2459 ppm Li from 155.6m
-
MDRC005: 18.3m @ 1992 ppm Li (incl. 9.2m @ 2440ppm Li) from 58.0m
-
MDRC006: 30.5m @ 1939 ppm Li (incl. 4.6m @ 3550ppm Li) from 39.7m 29.0m @ 2164 ppm Li from 97.6m
-
MDRC007: 29.0m @ 1948 ppm Li from 19.8m
-
MDRC009: 22.9m @ 2108 ppm Li from 6.1m MDRC010: 19.8m @ 2383 ppm Li (incl. 9.2m @ 3017ppm Li) from surface MDRC011: 22.9m @ 2283 ppm Li from 3.1m MDRC012: 58.0m @ 1611ppm Li (incl. 12.2m @ 2617ppm Li) from 1.5m
