For any new to the OGX forums -interested in the VMS-Multi-element potential mentioned in the presentation
here is some additional information to consider.

Ann ASX Release-13th June 2018 TINTEIRO ROCK CHIP SAMPLES
The three best assays of 1.54%, 1.65% and 1.75% cobalt were found 1.2km due south of our Cascavel high grade producing
gold mine in Area 3 known as Central Tinteiro.
Tinteiro rock chip samples grade up to 1.75% cobalt, 0.5% nickel and 0.6% copper .



The latest sampling program should be taken in context with previous exploration evaluations  
of Tinteiro-THAT USED MULIPLE DATA SETS TO EVALUATE -(not just rock chip analysis)

Often a company geo with a hawk eye spots an interesting specimen sample known as a rock chip its mentioned to market
& a flurry of interest unfolds as where did it originate from-the source millennia ago.

This is not the scenario here- couple of comments regarding the Ann & sampling first then its important to understand
& comprehend the comprehensive analysis that has already occurred prior to this second sampling program conducted by
OGX-GEO'S-that was conducted independently & utilised multiple data sets in the evaluation process while
evaluating Tinteiro's  potential to host significant IOCG  deposits.

These rock chip samples are numerous over a huge area.
This is the second sampling program on conducted in 2013 &  2014 in this 2014 program-567 chip samples were collected
along the trend, where several anomalies of Au, Ag, Cu, Co, Ni and W were identified, associated with the gossans and
breccias-(Several samples returned grades up to 1.2% of cobalt, 0.39% of copper, 0.56%of nickel,
23.9 g/t gold and 4,234 g/t silver).
There has been extensive evaluations made of Tinteiro's Exploration potential, some condenced information as to how extensive
below in extracts-for those interested here is the link Published in December 2017 in the Brazilian Journal of Geology -titled.
Prospectivity Analysis of Gold and Iron Oxide Copper-Gold-(Silver) Mineralisations from the Faina Greenstone Belt .
Prospectivity analysis of gold and iron oxide copper-gold-(silver) mineralizations from the Faina Greenstone Belt, Brazil, using multiple data sets

If you take a gander at figure 4, it clearly shows four areas are aligned trending North West-South East, very
strong indication when aligned as these are not just a couple of random rocks from an unknown origin.
These samples indicate over 6.3 kms of strike.
Together both programs appear to indicate the presence of a large IOCG-Iron Oxcide Copper Gold System that is also
inclusive of high grade Cobalt , samples also show they are inclusive of Nickle, Copper, Barium, Tungsten-Silver & Gold.

Note-Every sample was inclusive of Cobalt-yes that's right 54 samples taken in this latest program are all inclusive of Cobalt,
yes some one will say they were targeted samples -Yes the would have been & taken from four different area along some
6.3 kms of strike .
Note the presence of Gossans -mentioned several times in this & previous Ann-more on that latter .

Note this latest sampling program is on the back of not just the original rock chip program but the results are supported
by an independent study conducted of the Prospectivity Analysis of Gold and Iron Oxide Copper-Gold-(Silver) Mineralisations in the Faina Greenstone Belt- note MULTIPLE DATA SETS UTILISED -( not just rock chips)

This study would have been expensive it would have been conducted for a reason it was extensive it included the following
making up the multiple data sets utilized for evaluation -Not just rock chips

Aeromagnetic Data-Aeromagnetic and high-resolution gamma spectrometry surveys covering a total area
of 1,562.38 km² and with a flight altitude 50 m above the terrain.
Gamma Spectrometry Data-The gamma ray aerial survey shows the geochemical variations geophysical method is a
useful tool for geological mapping, and identification of hydrothermal alteration areas in different
geological environments

Images from the Landsat & Enhanced Thematic Mapper Plus (ETM+) sensor was used to interpret the main
geological features.

Geologic data obtained from two field trips.

Mineralogical and chemical behavior of the mineralized zones of the region," 7 of the 50 bore holes" that
intercepted the mineralized bodies of the Cascavel and Tinteiro target sites.

Chemical mineral analyses were conducted in the Electronic Microprobe Laboratory of the Institute of Geosciences
(UnB) using the superprobe model JEOL JXA-8230.

Petrographic studies of the transmitted and reflected light were undertaken using 70 thin polished sections and an
Olympus BX60FS microscope (Olympus Optical Co. Ltd.), by the Laboratory of Microscopy of the University
of Brasília (UnB).

Geochemical data comprise major, minor and trace elements of the mineralized zones and its surroundings.
These data were collected in samples obtained from boreholes, rocks and soil.

The analyses included a screen fire assay and inductively coupled plasma mass spectrometry
(ICP-MS), which were conducted by the laboratories ALS Minerals, Intertek, SGS Minerals Services
and ACME Analytical Laboratories Ltd.

The chemical elements included in this study were those that exhibited anomalous concentrations in certain
boreholes and field samples and included Au, Cu, Ag, Ni, Fe, Co and Ba.
The anomalous elements were selected for identifying anomalous zones and determine the correlation between
these elements and the previously mapped geological-structural features.

The integration of all data was conducted using ArcSDM software (version 9.3) (ESRI), with the objective
of creating the final exploration map using fuzzy logic technique.

So these rock chip samples should be taken in context & it would appear many were taken from structures that
were outcropping at surface -not just from a couple of rock chips found laying on the surface that had been
thrust upwards or carried over the surface over millennia, they are taken from structures that exist in situ
from faults & GOSSANS -that word again & fully supported by not just the previous sampling program but by
an intense evaluation that was conducted independently that used multiple data sets -not just Rock Chip analysis
while conducting- Analysis of Gold and Iron Oxide Copper-Gold-(Silver) Mineralisation's.

For those that don't Know .
Gossan, also spelled gozzan, rust-coloured oxide and hydroxide minerals of iron and manganese that cap an ore deposit.

Early days good intercepts & commercial grades need to be confirmed before getting exceedingly excited though the potential of
discovery is as high as it could be given the exploration evaluation that has already occurred .

Quiet obviously this is why OGX has contacted -Independent Polymetallic Specialist Mr Olavo Caramori Borges
to designed drill program at Tinteiro.
This in no way takes away from Cascavels potential non does it imply that Cascavel is not the priority its clearly exploration
that justifies pursuing as production ramp of Cascavel continues.

Note its very interesting that the highest grades of Cobalt & potential IOCG system determined in this latest program
are only 1.2 km's from Cascavels Mines & Gold Processing facility, further the 6-7 km's of strike trending  N.W.-S,E. structures
are offset & postdate the main Gold Bearing structure & are the result of two separate geological events occurring millennia apart
& that mapping Cascavel mine has shown that the high-grade silver and base metal mineralisation is related to the intersection
of a series of north-east trending faults and a dolomitic unit in the footwall of the main Cascavel gold structure.

So we have a possible convergence point close to Cascavel one heading North West & a separate heading North East..
