Quarterly Activities Report
Ventnor Resources Limited (ASX: VRX) (Ventnor or the Company) provides the following
summary of exploration activities conducted during the December 2016 quarter:
Exploration
During the December quarter the Company conducted Moving Loop EM surveys at the Silver
Dragon and Fire Dragon prospects at the Biranup Project in Western Australia. Following the
survey which identified conductors at Fire Dragon and Silver Dragon, the Company drilled
three deep RC holes during the quarter at both Fire Dragon (2 holes) and Silver Dragon (1
hole). Results, scans and interpretation are still pending. The Company continued evaluation
of the database collated on the Biranup Project with the aim of identifying further drill targets.
Extra ground was applied for in the Biranup project area with a total ground holding now of
370km2.
Background to Biranup
Biranup was formerly known as the Black Dragon Gold Project. When granted in March 2015
the 42 graticular block EL39/1828 was referred to as the Black Dragon Gold Project, however
subsequent work by Ventnor has identified multiple exploration targets on the 140 sq km area.
These exploration targets are prospective for various minerals as well as gold and to avoid
confusion and easier identification the tenement was renamed the Biranup Project area with
each target area individually named.
Ventnor’s Biranup Project is proximal to the Tropicana gold mine owned by AngloGold Ashanti
and the Independence Group. Tropicana commenced production in 2013 and contains a
resource in excess of 4Moz situated 22 kilometres to the south-west of EL 39/1828.
EL39/1828 was previously explored in the 1990s by WMC and more recently by the AngloGold
Ashanti and Independence Group joint venture, which generated a large dataset of geological
information over a 7½ year period.
AngloGold explored the ground for Tropicana-style gold mineralisation, being a 30o south-east
dipping, tabular orebody characterised by biotite-sericite-pyrite alteration of the host gneisses.
The primary exploration technique used was vertical aircore drilling on a 200m x 200m drill
pattern, and sometimes 400m or wider lines, drilled to blade refusal, with routine gold assays
down-hole and bottom-of-hole multi-element assays. Limited RC and diamond drilling was
conducted in areas of stronger gold anomalism. The result of this exploration effort is that
Ventnor has inherited a large database of geochemical multi-element assays and geophysical
surveys that are invaluable in targeting not only gold mineralisation, but other precious and
base metals.
The database includes assays of soil samples, auger samples, AC, RC, and diamond drilling
results, along with a significant geophysical database including gravity/mag and EM surveys.
The Company has used specialists to evaluate all of the components of the database and has
examined concurrent anomalies.
In adding to the geological knowledge of the tenement Ventnor has been able to reinterpret
the regional basement geology, isolating a promising gold anomaly, and identifying an
anomalous NiCu zone.
The basement geology has been re-evaluated at project scale using available drill data, and
a new interpretation has highlighted an area to the west of the tenement with a subdued
magnetic response which coincides with a low embayment in the regional gravity data. The
potential for a granitoid intrusion is supported by soil and auger assays indicating the area is
depleted in Mg but enriched with Pb, Sb, As and W, which provide fertile ground for further
exploration.
The new interpretation has identified three mineralisation styles:
Tropicana Style – Au in K-rich shear zone within high-grade gneisses. Younger than
Yilgarn gold and with a limited alteration halo.
Voodoo Child Style -- associated with 1750Ma intrusions into localised pull-apart
basins, diverse rock assemblage, target structural ‘traps’ in Proterozoic and Archaean
rocks, identifiable in magnetics. Other intrusion-hosted potential may exist.
Shear Zone Style – remobilisation of Au, SZ’s identified on magnetics commonly show
Au anomalism (e.g., Black Dragon), target second order shears and dilatant zones
next to major SZs.
New basement geology interpretation
Specific Work Conducted during the Quarter
On 13 October 2016 Ventnor advised the market of the commencement of geophysical
surveys at its Silver Dragon and Fire Dragon prospects in the Biranup Project area. The two
target surveys that were completed at Biranup utilised Moving Loop Electromagnetic (MLEM)
geophysical technology to investigate the prospective areas. Following the identification of a
compelling bedrock anomaly the geophysical survey was expanded to include further survey
lines to better define a target for future drilling. The market was advised on 1 November 2016
and the program was completed during the quarter.
MLEM survey over SPECTREM electromagnetic anomalies
Initial ground electromagnetic surveying has successfully delineated a bedrock conductor
anomaly at the Fire Dragon Prospect. The moving loop EM program was designed to follow
up two anomalous EM responses identified from a recent review of SPECTREM data acquired
by the previous tenement holder. Three MLEM survey lines were carried out to define the
strongest SPECTREM anomaly in the south of the prospect area; results received indicate an
extension of the conductive response to the north/northwest.
Results from a single MLEM traverse carried out across the weaker SPECTREM anomaly, in
the north of the prospect area, indicate a strengthening of the conductive response to the
south of the survey line. After the success of the initial MLEM surveying at Fire Dragon,
additional MLEM traverses were designed to provide complete coverage and to identify where
the anomalous EM response is strongest. With this information, Ventnor generated high
priority drill target areas to confirm the source of this conductive response.
Completed MLEM survey lines (Red) and new proposed lines (Yellow) over Aeromag
and Spectrem image, with preliminary plate model.
(Image below shows the program.)
Following the MLEM surveys Ventnor commenced RC drilling in early November at its Silver
Dragon and Fire Dragon base metal prospects within the Biranup Project area seeking to define
mineralisation at the two targets generated from the MLEM surveys.
The prospectivity of both the Silver Dragon and Fire Dragon prospects is also well supported
by coincident geochemical results, which are anomalous in base metals. The drilling at Fire
Dragon was to test the mineralisation of the MLEM conductor, while the hole drilled at Silver
Dragon was to be set up to enable a down hole EM survey to undertaken.
Fire Dragon
Fire Dragon became an area of interest as reported on 15th November 2015, and subsequently
Ventnor acquired 50m line spaced aeromagnetic and 500m line spaced airborne EM
(SPECTREM) data from the previous tenement holder. The analysis of these data sets
motivated the recently completed MLEM survey.
MLEM surveying was carried out along 200m spaced E-W traverses to follow up on a strong
anomalous conductor response identified from the SPECTREM survey. The ground EM
survey resolved a strong anomalous EM response indicative of a bedrock conductor. The EM
anomaly is also associated with a weak magnetic anomaly. The EM and magnetic anomaly
responses have been modelled by geophysical consultants and high priority drill target areas
were identified.

colours on a magnetic image of the prospect area
Analysis of the existing geological dataset generated from previous drilling supports the
geophysical interpretation. Geological logging of the holes suggested that Fire Dragon is
largely covered by transported sediments to a depth of 60-80m and geophysical modelling of
the anomalous EM response suggested a depth of greater than 100m to the top of the MLEM
conductor. This was born out by the RC drilling conducted during November 2016 and
completed early December 2016.

image. The trend line in green is where the conductor plate has been projected up to intersect
the top of the basement, and then interpreted from the magnetics.
Silver Dragon
MLEM surveying was carried out at the copper-nickel Silver Dragon prospect using regionally
spaced traverses (400m) and 100m spaced stations. The MLEM survey was designed to try
and identify conductive bedrock EM anomaly responses for further follow up in the prospect
area associated with magnetic and geochemical anomalism
The Silver Dragon MLEM survey results have assisted interpreting the geochemical samples,
and has identified a very subtle anomalous response to the west of the WMC 1997 soil sample
highlighted in the following figure. The anomaly has been modelled by geophysical consultants
to provide a vector for drill targeting. Drilling will be followed up with a downhole EM (DHEM)
survey.

It should be noted in addition to the image above is that of a LAG soil sample taken by Western
Mining Corporation (WMC) in 1997, which returned a value of 315ppm Ni and 160ppm Cu
above very low background. WMC commenced exploration in the area with a large tenement
holding as their Pleiades Lakes Project, with the stated aim to target the area for Voiseys Bay
style mafic hosted nickel sulphide deposits. The project focused on 14 magnetic anomalies
generated from a large aeromag survey over a 3 year period.
Of the 14 magnetic targets, one target (PL6) stood out as having the most significant nickel
and copper anomalism. The soil sample shown on the image above followed an anomalous
rock chip taken from the outcrop at Silver Dragon. This position is proximal to the identified
contactor and makes for a compelling target to be investigated as proposed.
Co-Funded Drilling Grant
In early December Ventnor announced it has been awarded a drilling grant by the Western
Australian State Government as part of the Co-Funding Industry Drilling Program. Ventnor
was awarded $125,000 to progress its drilling program at Silver Dragon.
The grant by the West Australian State Government is aimed at supporting innovative drilling
by companies in greenfield areas, where additional drilling and promotional activities will
potentially lead to new discoveries.
The co-funded drilling program is designed to fund high quality, technical and economically
based projects which promote new exploration concepts and technologies.
Proposals were assessed by a panel on the basis of geoscientific and exploration targeting
merit.
New Ground applications
Ventnor has made application for four Exploration Licences adjacent to the Biranup Project.
The additional licences are for 77 graticular blocks for a total project area of 370 km 2.
The priority for these new areas is for the Company to once again accumulate the historic data
applicable to the areas. A significant geophysical, geochem and drilling database is available
which will enable Ventnor to isolate areas of interest and select prospects for further
exploration for base metals and gold.
Thaduna/Green Dragon Copper Project JV
The Thaduna Project is located 40km east of DeGrussa and represents the largest copper
resource in the Doolgunna-Bryah Basin Region outside of Sandfire’s Degrussa-Doolgunna
Project (7.9Mt@1.8% Cu for 142,000 tonnes of contained copper). Until 22 August Sandfire
owned a 35% interest in the Thaduna/Green Dragon project, and had entered into a farm-in
agreement with Ventnor Resources Ltd to earn a further 45% (total of 80%).
Ventnor announced on 22 August 2016 that Ventnor Resources Ltd (Ventnor), Delgare Pty Ltd
(Delgare), a wholly owned subsidiary of Ventnor, and Sandfire Resources NL (Sandfire) had
executed agreements for Sandfire to purchase the remaining 65% of the Thaduna/Green Dragon
Copper Project with Ventnor to maintain a royalty interest.
The Ventnor board ensured the sale agreement was structured to produce the same or very
similar outcomes to those of the JV once mining of the resource commences.
Events Subsequent to the Quarter
Subsequent to the period Ventnor announced a follow up diamond drilling program at the Fire
Dragon prospect in the Biranup Project area for late January 2017. A multi-purpose RC and
diamond drill rig has been mobilized to site to drill an RC pre-collar with a diamond tail to drill
deeper down the conductor and to generate drill core. This will allow for a much better
understanding of the host rocks in the Fire Dragon area and to intersect the strongest
conductive area, testing for nickel and copper sulphides. Also, the drill hole will be cased with
PVC to undertake a DHEM survey, and if possible, the 2 RC holes will have the PVC re-instated
to be included in that survey.
Assays for this program are expected towards the end of the March quarter.
The program follows the two-hole Reverse Circulation (“RC”) program in late 2016, following
up on two targets generated from the previous MLEM survey. As reported, the RC drilling
intersected a pervasively sulphidic, predominantly pyrrhotite, mafic rock, with discrete zones of
semi-massive to massive sulphides. Assay results have been received that confirm these
zones are associated with peak copper, nickel and cobalt values and are anomalous, when
compared to the background values in the rest of the holes, by an order of magnitude,
warranting deeper drilling.
Selected chips from FRC001, similar to those below, were sent to A & A Crawford Geological
consultants, Tasmania to determine the nature of the host rock and origin of the sulphides.
This analysis determined that, in one sample, the host rock was “unambiguously a medium
grained, mafic granulite likely derived from a gabbro or gabbronorite protolith”. It has been well
documented that the protolith of the magmatic intrusive body that gave rise to the Nova –
Bollinger magmatic nickel copper deposit was a gabbronorite.
The thin section analysis indicates that the host rocks at Fire Dragon are of the right type and
origin to generate a magmatic base metals deposit.
In addition to this work, a down hole electromagnetic survey (“DHEM”) was attempted on the
2 RC holes that were drilled at Fire Dragon to better determine the best target to test the
known conductor. Unfortunately, the PVC casing that was installed become blocked, which
precluded the survey from successfully testing the lower sulphide rich zones.
Whilst the geophysical survey crew was onsite additional lines of MLEM were surveyed. This
data has allowed for better modelling of the conductor and to generate a new drill target. The
eastern line has confirmed an additional conductor that will require further surveys to
determine the orientation.
