can anyone remember where/when the IP anomaly
G'Day B.B.-See pg -8 - 31st July 2018 2nd Quarter Activities Statement.
See highlighted below
As part of this review, the Company conducted a detailed study of the Sertão Prospect
which has an existing JORC Mineral Resource estimate of 223,111 tonnes at 6.9g/t for 49,268 ounces of contained gold.
As a result of this work, an IP anomaly consistent with existing ground geochemistry has been identified
directly to the west of the Sertão Stage 4 and Stage 5 open cut pits.
Sertão Stages 1-4 and 5 was mined by Troy Resources between 2002-2006 and produced 256,000 ounces
(189,500 ounces Stages 1-4 and 54,200 ounces in Stage 5) at an average grade of 25 g/t.
The Sertão Stage 4 and Stage 5 orebodies were 65m and 25m wide respectively and were intensely mineralised and
structurally controlled along the shallow sections previously mined by Troy.
Our exploration team are of the view that the previous attempts by OGX in 2015 and 2016 with the STO001 to STO023
drilling campaign, failed to conclusively define the continuation of the mineralisation along strike due to drill spacing in
excess of 80 m, however, a review of the data gained from this campaign does successfully define sections of continuation
of the ore shoots with drill holes STO004, STO005, STO006, and STO022.
Further analysis of the geochemical data from all existing drill holes in the area directly to the west of Stage 4 and Stage 5 pits,
including STO001, STO002, STO007, STO008, STO009, STO010 and STO011 indicates zones of intense alteration
which is interpreted to identify the extremities of the mineralised ore shoots.
These results were reported on 28 January 2016 entitled Completion of Orinoco’s Maiden Sertão Drilling Campaign.
Analysing the data gathered from the 2015 campaign with historic data from SML, Troy, WMC and the SRT001 (Yamana)
drilling together with the existing induced polarisation survey of the project provides very strong support for the
theory of continuation of the intense mineralisation along a structurally controlled fluid pathway to the west
and north.
Our exploration team view the findings of this modelling to indicate potential significant extensions of the Stage 4
and Stage 5 orebodies.
Three additional high priority targets, Nena, Estrella and Santa Rita have also been identified in this systematic
ongoing review so far.
The significance of these three targets were not previously understood by the Company as the exploration at the
time wasn’t completed by Troy / SML as they were explored just before Troy shifted owing to a shift in focus from this region
to their Andorinhas Project.
