Projeto de Lítio Solonópole

A large-scale, significantly underexplored lithium opportunity in Northern Brazil

Historic Mines

Solonópole permits cover historic artisanal mining sites previously mined for lithium, Coltan (tantalum and niobium) and tin.

Over 20 historical small-scale mines have been identified in field exploration. Mining was only undertaken to less than 10 meters vertical depth due to restrictions of hard pegmatite material requiring blasting.

Large-scale opportunity, Significantly underexplored

10 permits covering 124km2 of highly prospective ground
Detailed field mapping by Oceana’s Brazilian subsidiary Ceara Litio has identified an approximate 20km outcropping mineralized pegmatite corridor within the Oceana tenement holding
Regional geological assessment of the Solonópole Pegmatites was initially completed in 2012 by the Brazilian geological survey department (CPRM). Analytical results (XRD) confirmed lepidolite, amblygonite and spodumene being the main lithium minerals
Outcrop grab samples confirm mineralized pegmatites with anomalous results for lithium, tin, tantalum and niobium

Ongoing Exploration Work Program & Access

Qualified and dedicated in-country team to execute on the exploration strategy
A large-scale infill soil sampling program has commenced in March 2023 over prioritised wider spread 2017 anomalies identified by previous explorer Cougar Metals NL, as well as CPRM mapped pegmatites and artisanal workings. The sampling grids are along 200m spaced lines with 25m sampling stations, aligned north-south in order to cut across all typical pegmatite strike directions in this area. Over 8,300 soil samples have been collected until December 2023
First pass 2,000m RC drilling program across priority targets completed in August 2023 confirmed presence of Lithium mineralised LCT Pegmatites at shallow depth
Trial hyperspectral remote sensing survey, and high-resolution magnetics and radiometrics geophysics surveys completed over selected pegmatite and soil grid targets
An all-weather drying greenhouse has been set up at Oceana’s Solonópole field base, as well as an XRF for the assaying of Li pathfinder elements. Two containers and a warehouse are also on site to provide secure lock-up sample storage

Key Exploration Results

383

Anomalous lithium values above 100 ppm (and up to 631 ppm) found in 383 soil samples within several target areas

~2,000m

Integration and interpretation of these soil sample results with data from geophysics, geological mapping (125 line km), trenching and RC drilling (~2,000m) have further enhanced prospectivity of these targets

BJdB

Bom Jesus de Baixo (BJdB) Prospect is the most advanced exploration target at the Solonópole Project

NE–SW

Combined datasets confirm several swarms of pegmatite bodies striking in a NE-SW direction and identify new high priority areas

524ppm

Nira interpreted to be the most prospective new target, with 180 soil samples of >100 ppm Li and as high as 524 ppm Li covering an area of at least 1km2

30m

Nira also features 17 pegmatite outcrops with average widths of up to 30 meters and strike lengths from 200m to 600m
