New target SP, page-12

When you are considering the medium to long term SP, it's important to keep in mind that the Cartesian royalty payment is time-limited, provided the minimum is reached, and it is also geographically limited.

The Cartesian royalty is time limited:

OGX made a payment of 380 oz gold to Cartesian in December 2017/early Jan 2018 (see Ann on 3rd Jan 2018):

"Orinoco Gold Limited (ASX: OGX) (Orinoco or the Company) is pleased to announce the first payment to its gold streaming partner Cartesian Royalty Holdings (CRH), totalling 380 ounces of gold. The next minimum payment under the streaming arrangement is due on April 30th, 2018 or earlier depending on the gold production levels of the 1Q2018."

This implies, but doesn't state explicitly, that Oct to Dec 2017 is the first quarter in the 3 year period.
in that case, the 3-year payment period ends with gold mined by 30th September 2020,
provided the minimum of 17,600 ounces has been paid.

If you are a long-term investor, as I am, then the Cartesian royalty is not relevant to the long term SP.

The Cartesian royalty is geographically limited:

The Cartesian royalty applies to gold from Cascavel only.

It does not apply to  any gold OGX finds and processes from other tenements that are now funded for an expanded exploration program such as Sertão, Tintiero, Antena and Eliseo.

IMOO,
All the best,
