In March 2015, the Company’s Peruvian subsidiary, Agrifos Peru S.A.C. completed a purchase agreement with the shareholders (the “Vendors”) of Juan Paulo Quay S.A.C. (JPQ), titleholder of the Bayovar 12 phosphate mining concession (the “Bayovar 12 Project”) located in Northern Peru, whereby the CROPS acquired a 70% interest in shares of JPQ (the “Bayovar Interest”).

During the period ended June 30, 2020, CROPS and the Vendors began a process for JPQ to relinquish the Bayovar 12 Project.

The CROPS is currently taking the necessary steps to dissolve Juan Paulo Quay, SAC (“JPQ”), the Peru company which holds the Bayovar 12 concession, and to transfer the concession back to the Peru government.

Deposit type

  • Sedimentary

Summary:

The Bayovar-Sechura Phosphate Deposit occurs in the Sechura Basin, a shallow north trending basin situated in northwestern Peru. The basin is filled by a thick sequence of interlayered marine sediments including phosphorite, diatomite, sandstone, shale and volcanic tuff, ranging in age from Eocene (56.0 to 33.90 Ma) at the base to Pliocence (5.33 to 2.58 Ma) in the upper basin.

The phosphate bearing units occur in the upper 135 to 215 m of the Miocene (23.22 to 5.33 Ma) strata in the basin, within the Zapallal Formation. The phosphorite beds are comprised primarily of massively bedded phosphate pellets with lesser grains and fragments of diatoms, volcanic glass; evaporate salts; quartz; feldspar; sponge fragments; gypsum, mica flakes and organic matter. The phosphate is marine in origin and is generally in the form of the mineral francolite, a fluorhydroxycarbonate apatite.

The apatite is generally in the form of individual pellets although agglomerations of pellets, oolites, laminae, nodules and fragments of teeth, bones or shells are also present. The pellet grain size ranges from 0.4 to 2.0 mm in diameter, with larger pellets occurring in the phosphorite beds while finer grained pellets occur in the diatomite.

The diatomite ranges in color from white to brown to olive green. The diatomite generally has high porosity, often on the order of 90%; as a result of this and its resistance to compaction, the specific gravity is very low, typically the wet density is around 1.5.

The Zapallal Formation stratigraphy dips gently to the east within the Bayovar 12 Concession. No faulting or folding was identified within the concession.

Focus has intercepted 16 distinct and correlatable phosphorite beds (identified as PH01 through PH16) across the concession. Focus and Golder have interpreted the upper 13 phosphorite beds (PH01 to PH13) as Diana ore zone beds that have been modeled as mineral resources. The phosphorite beds range in thickness from 0.31 meters to 1.76 meters. The individual phosphorite beds exhibit relatively uniform thickness and P2O5 grade profiles across the concession; however, there is a pronounced zonation of P2O5 grades in both the phosphorite and diatomite beds that effectively divides the Diana ore zone into an Upper Diana ore zone and Lower Diana ore zone.
