ASX Announcement

Initial Exploration Results - San Jorge Lithium Project, Argentina 2 December 2021

Greenwing Resources Ltd (ASX:GW1 or the Company), an emerging fully integrated green metals company, is pleased to report the results from its initial exploration program at the San Jorge Lithium Brine Project located in the prolific Lithium Triangle in Argentina.

Greenwing has received results of the initial 34 brine samples from the San Jorge Project, and the full results of the geophysical survey.

HIGHLIGHTS

  • Highly encouraging results with the initial 34 brine samples taken from surface at the San Jorge Project confirming the presence of lithium.

  • Brine samples further confirm an area of elevated lithium in the centre-south of the salt lake, with concentrations up to 285 mg/L lithium.

  • Detailed interpretation of the initial passive seismic geophysical survey completed suggests the basin may extend to a depth of up to 600m (+/- 200m) in the south of the salt lake, significantly deeper than the initial estimate of 300m (ASX announcement 26[th] October 2021).

  • The salt lake is currently interpreted to extend beneath gravels and thin lava flows that surround the visible extent of the salt lake.

  • A drilling program is being designed to follow up these highly encouraging initial results.

  • In parallel with ongoing exploration Greenwing has commenced assessing processing options for San Jorge including low-cost direct lithium extraction (DLE) technology.

San Jorge Lithium Brine Project

Greenwing’s highly prospective San Jorge Project is located at the San Francisco Salar and covers a total of 38,800 hectares.

Key details of the San Jorge Project are as follows:

  • 15 granted exploration licenses

  • Lithium Triangle location which accounts for over half the world’s lithium production (refer figure 1)

  • Elevation of 4,000m above sea level

  • 2,800-hectare San Francisco Salar, surrounded by gravel slopes, under which the salar may extend

  • Exploration Licenses cover 100% of the salt lake (refer figure 2)

Results of brine sampling

Brine samples were taken on an approximately 1km square grid. The brine sampling has confirmed the northern area of the salar hosts brackish water and is the lowest concentration area of the salt lake. Inflow of brackish water is also noted around the edges of the salar from runoff and from hot springs noted on the western side of the salar.

In the centre of the salar, the lithium concentration from initial samples reached a maximum of 285 mg/l, within a zone of predominantly 104-150 mg/l lithium concentration (Figure 3). Lithium concentrations of up to 285 mg/l are a positive indicator of the Salar potential.

Planning of further field work to evaluate the brine concentration is underway. More consistent and possibly higher concentrations of brine may exist at depth, which can be confirmed with further drilling.

Geophysical survey interpretation

A Tromino passive seismic survey was conducted, providing valuable information regarding the potential thickness of the salt lake sediments. The survey technique allows the definition of units with different density/consolidation and a contrast in seismic properties. It is effective for mapping the contact of salt lake sediments with the underlying basement rocks. In the south of the project clear high confidence reflectors were identified (Figure 4), which suggest the salt lake sequence is in the order of 300m to 600m (+/- 200m) thick. The planned drilling program will be designed to confirm these results.

==> picture [436 x 112] intentionally omitted <==

Figure 4: Tromino passive seismic line A0 from the south of the project

In the north of the salt lake a shallow reflector is interpreted to reduce the signal from below this feature and the depth of the salt lake basement rock contact is poorly defined and less certain. The shallow reflector in the north of the salt lake is likely to be a volcanic unit close to or at surface within the salar, with outcropping areas of basalt mapped in the north of the salar, most likely basalt flows from volcanos in the area. Additional passive seismic measurements are planned to better define the distribution of units and the presumed thickness of the salar sediments.

Drilling will be required to obtain deeper brine samples and to assess the types of sediments present in the salt lake and their porosity characteristics.

An initial drilling program is under consideration, with the Company also awaiting receipt of the relevant permits to allow drilling on the project.

RICK ANTHON, CHAIRMAN

Greenwing is pleased with the initial exploration results delivered at San Jorge confirming the presence of lithium. Greenwing are particularly pleased with the depth of the basement contact increasing from 300m to 600m (+/- 200m) which significantly expands the potential volume of brine present. The next steps for San Jorge are to drill and in parallel commence assessment of competing direct lithium extraction (DLE) technologies.

We look forward to updating the market on this project along with the ongoing work program across Greenwing’s diverse battery mineral projects, including results from the diamond drilling program at the Graphmada Mining Complex in Madagascar which has now commenced, and ongoing research results from Swinburne University over the coming period.
