The drilling is targeting a large carnallite resource within the Sergipe Basin, similar to the style of mineralization being developed by Vale as described below.
There, the carnallite is dewatered, crystallized, leached, dried, and screened into three grades of potash.
They include carnallite, cuprite, dolomite, gypsum, halite, hematite, magnesite, pyrite, quartz, rectorite, rinneite, sylvite and syngenite.
It is known that potash also contains small amount of carnallite and halite (i.e., less than 2%).

The plant was to switch to another type of raw material, solid dehydrated carnallite, which would reduce energy consumption during smelting and would enable the plant to skip the de-watering phase and go straight to electrolysis.
The evaporite beds are mainly sylvinite (co-deposited sylvite and halite) with carnallite in places.
Other cover fluxes are based on Mg|Cl.sub.2~ and KCl, which form a low melting eutectic--800F (425C), or Mg|Cl.sub.2~xKCl (carnallite), which melts at a slightly higher temperature--910F (485C).
It is composed of alternating layers of halite, clay, anhydrite, gypsum, sylvite, polyhalite, and locally abundant carnallite, langbeinite, and lesser salts.
However, the dominant minerals containing potassium chloride in Canada, as in the other major world deposits, consist of potassium chloride co-crystallized with either magnesium chloride (carnallite, KCl*[MgCl.sub.2]*6[H.sub.2]O) or sodium chloride (sylvinite, 2NaCl*KCl).
It is anticipated that if chemical assays from Area B confirm field observations of extensive sylvinite, carnallite and kainitite mineralisation similar to that demonstrated at Area A, the economics of the entire Colluli Project will be substantially enhanced.
