Vancouver, British Columbia--(Newsfile Corp. - July 17, 2023) - Solis Minerals Limited (ASX: SLM) (TSXV: SLMN) ("Solis" or the "Company") is pleased to announce the intersection of spodumene bearing pegmatite in the 2,500m maiden drill programme at the Jaguar Lithium Project Bahia state, Brazil over which the Company has recently secured an option to acquire a

The Drilling Programme
Diamond drilling at the Jaguar project is ongoing with three drillholes now completed. As the orientation dip and plunge of the mineralised portion of the first pegmatite target was unclear from outcropping mineralisation, drilling was planned from both the hanging wall and footwall locations North and South of the pit. Drillhole JADDH00001 did not intercept the core of the pegmatite due to incorrect drill orientation. JADDH00002 and JADDH00003 both successfully intersected broad intervals of shallow dipping pegmatite below the existing artisanal workings at Jaguar. Spodumene rich central core sections of the pegmatite were intersected from 30m to 38.2m in JADDH00002 and from 44.3m to 52.2m in JADDH00003, respectively (Table 1, Figures 2, 3 & 4).

Executive Director, Matt Boyes, commented:
"This is a positive result for the team from the maiden programme at Jaguar. Confirmation of an LCT - (Lithium-Caesium-Tantalum) bearing system that continues at depth below the artisanal workings is highly encouraging and we look forward to the arrival of a second drill rig.
As we extend our mapping and geochemical sampling programmes, we are finding evidence of a potential stacked pegmatite system. Multiple spodumene bearing float samples have been collected up to 1 kilometre from the central Jaguar artisanal mine area and large outcropping pegmatites, which are completely untested, have been located.
We are encouraged by our early results at the Jaguar project, and we look forward to updating the market as we deliver results from this maiden drill programme."

*In relation to the disclosure of visual occurrences of pegmatite and spodumene, the Company cautions that visual estimates of mineral abundance should not be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations.
Initial production rates averaged just 7m per shift, with crews encountering start-up technical challenges. These have been fully addressed, with drilling now expected to achieve normal production targets. Continuous mineralisation has now been confirmed below the existing artisanal workings, and Solis is sourcing a second rig. A tender has been called for an additional 5,000m diamond core drilling programme with a larger capacity track mounted rig capable of higher production rates and higher availability. This is expected to improve the drilling rates which have been less than targeted.
Step out drillholes along the interpreted strike of the pegmatite are now planned to help understand the overall strike, dip and distribution of the mineralisation within the pegmatites. The drilling to date has intersected pegmatites which adhere to a classic idealised LCT bearing pegmatite model. The mineralisation grades from an Albite-Quartz-Muscovite rich border zone through to a K-Feldspar rich intermediate zone and then grading to a Tourmaline-Quartz-Spodumene rich core. The pegmatites are orientated in a north-east strike and are dipping at approximately 30 degrees to the south-east, parallel to the slope of the ridge line that is formed by the pegmatite.
Solis is currently installing core cutting facilities on site and intends to start processing the existing core within the next week. Solis will be aiming to complete a further 3 holes from the current programme and submitting the first batch of samples in late July with results expected late August. All samples will be assayed at SGS Laboratories in Minas Gerais province with current turnaround period of 3 weeks post submission of samples.

Exploration Programme and Additional Targets
The initial focus of Solis during this maiden campaign is to test the known strike of the confirmed pegmatite outcrops at Jaguar and commence step out drilling to the north to test interpreted repetitions of the Jaguar pegmatites at depth. Pegmatite outcrops have been identified over 1.4km of strike with a central section that forms the elevated ridge area (See Figure 5) of in excess of 800m within the Jaguar tenement area. Mineral species identified in all the outcropping artisanal workings are consistent with an LCT - bearing system and fit a classic pegmatite model. The insert photo in Figure 5 shows very large individual feldspar and beryl crystals within an albite matrix.
Figure 5 below gives a spatial overview from a drone image of the follow up priority target areas.
A large shallow dipping pegmatite body measuring approximately 400m x 400m at the surface has been mapped approximately 1 kilometre to the north-west of the Jaguar pit and will be drill tested once additional drill capacity is mobilised to site. This pegmatite body exhibits classic mineralisation and textures associated with LCT- bearing systems. Spodumene bearing float has been found at surface in the vicinity of the outcrop with the source of the mineralisation yet to be located. The body has a similar dip and strike orientation to the Jaguar mineralisation which was intersected in the current programme and represents a potential repetition and hence the possibility for a stacked system with multiple pegmatite bodies to be hosted within the tenement package.
Figure 6 shows the outcropping pegmatite with textures and mineralisation identified from initial field reconnaissance and mapping.
