Solonopole Lithium Project Brazil

Historic Mines

  • Solonopole 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

  • 8 permits covering 114km2 highly prospective ground
  • Detailed field mapping by Oceana Brazilian subsidiary Ceara Litio has identified an approximate 20km outcropping mineralized Pegmatite corridor within the Oceana tenement holding
  • Regional geological review of the Solonopole Pegmatites was completed in 2012 by the government Geological Survey DNPN. Analytical results (XRD) confirmed Lepidolite, Amblygonite and Spodumene being the main Li-Minerals.
  • First pass soil geochemistry (400m x 400m grids) highlights residual soil anomalies within interpreted mineralization corridor
  • Outcrop grab samples confirm mineralized pegmatites with high grade lithium, tin, tantalum and niobium

Ideal project location

  • One of 2 historical lithium mining regions in Brazil
  • The second known lithium region in Brazil is in the state of Minas Gerais where TSX and Nasdaq listed Sigma Lithium Corp (> CAD$1.4 billion market cap.) is developing the Grota do Cirilo Lithium Project

Sampling 2018

  • Outcropping Pegmatite swarms were identified during detailed geological mapping
  • A regional sampling program resulted in the collection of 246 grab samples
  • Geochemical results show LCT pegmatites enriched in Li, Be, Ta, Nb & Sn over the full strike length of the recognized mineralized Pegmatite corridor with the best results shown below
    • Lithium > 9% Li2O
    • Tantalum > 1% Ta (detection limit)
    • Niobium > 1% Nb (detection limit)
    • Tin > 1000 ppm
    • Beryllium > 2.5% Be (detection limit)
  • Thin residual soil cover suited for exploration via traditional soil sampling and geochemical analysis.
  • A regional soil sampling program was conducted on a wide spaced 400m x 400m grid with some infill sampling
  • Initial soil sampling results highlight significant Lithium soil anomalies within the mineralized corridor.
  • Additional infill soil sampling combined with geological mapping are required to refine anomalies for drill testing

Exploration Work Program & Access

  • The key exploration activities to commence upon listing:
    • Infill soil geochemistry down to a 50m x 50 m grid across identified lithium anomalies
    • Trenching across lithium anomalies and outcropping areas
  • Oceana has a dedicated in-country team to execute on the exploration strategy
  • Oceana has engaged Sahara Natural Resources for Project Management and execution of all in-country exploration activities. Sahara have an in-depth understanding of the project and have completed all the historic field exploration at Solonopole
  • First pass RC drilling program across priority targets to test the mineralisation extent at depth
  • The topography, land use and vegetation at Solonopole is well suited for exploration activities
  • Arid, sparsely populated farm-land, No rain forest
