 Programme Highlights                           Explanation

 Drilling Overview                              The Diamond Drilling programme consisted of 988 metres in six drillholes, four
                                                of which encountered visible gold mineralisation.
 Extensive Gold Confirmed                       All drillholes returning gold mineralisation in laboratory assay test results.

                                                Multiple gold (Au) mineralised intersections were encountered including
                                                drillhole BE23D002 which returned 5.2m at 2.38g/t Au including 0.2m at
                                                34.76g/t Au, and BE23D006 which returned 3.5m at 5.43g/t Au including 0.7m at
                                                23.9g/t Au.
 The "Nugget Effect"                            Variability in grade was experienced due to "nugget effect" typical of the
                                                area, and this led to changes in the sampling protocol. Additional drilling
                                                will be needed to determine a representative grade.
 Key Objectives Met                             Key objectives of this drill programme have been met with drilling
                                                successfully intersecting the down dip and along strike extensions of
                                                previously mined Berringa gold mineralised quartz reefs. As the gold is hosted
                                                in the quartz reef the identification of a larger volumes of quartz reef is a
                                                positive development.
 Extensive Quartz Reef Confirmed in Final Hole  The final drillhole BE23D006 intersected a more than 30-metre-wide quartz reef
                                                intersection approximately 100 metres east of the main Berringa line of
                                                workings. The hole was ended while still in mineralisation and so is open at
                                                depth.
 Next Steps                                     The programme has enabled the partners to gain a better understanding of the
                                                structure of the historic Berringa gold mine and this work will be further
                                                advanced as the results continue to be analysed and related to historical
                                                data. The partners will then announce the next phase of exploration.

 

Red Rock CEO Andrew Bell commented:

"The work of our team, who are all experienced in the area and have worked in
the nearby Ballarat Mine, was so precise that this very small drill programme
was able to achieve successful results in almost every hole. This is an
exceptional achievement. Our structural understanding has been advanced, and
our assessment of the prospectivity of the Berringa area has been confirmed
and enhanced.

A key takeaway was that any intersection over 0.1 g/t is evidence that one is
in the mineralised system, and that any fire assay result (on typically a 50
gm split of a 500 gm sample) at 0.1 g/t or above should lead to the whole
sample being subjected to a KCN bottle roll test. This protocol compensates to
the extent practicable for the variability produced by the nugget effect.

Overall this was a successful, disciplined, and cost-effective programme.
Further analysis of the data will determine the next steps."

Programme Overview

Drill programme assay results from the Company's inaugural diamond drilling
campaign at its historical Berringa mine Project located in Victoria,
Australia, have confirmed extensions of gold mineralised lodes within the main
reef systems.

The limited programme was specifically designed to test three potential sites
for further evaluation and has exceeded expectations with visible gold
identified in 4 of the 6 holes drilled.

All targets tested have proved the mineralised quartz lode systems are
continuous and open down plunge and along strike.  All zones require further
diamond drilling to build on the early success and work towards possible
Resource definition.

Gaining access to the mine through an historical adit has also become an high
priority to enable bulk sampling of the Berringa syndicate lode for
preliminary metallurgical test work. This will accelerate the process to
recommence gold mining at the historical mine site. This work is continuing,
subject to regulatory requirements and approvals from the State Government
regulator.

Geological Interpretations

South Birthday Zone - Drillhole BE23D001

A single long drillhole, BE23D001, was completed targeting a possible
extension of the west-dipping lode in the South Birthday Zone, and
investigating possible similarities with the reef system currently mined at
Ballarat 20km to the east. BE23D001 successfully intersected a fault structure
of approximately 9 metres in width which extends the west dipping lode over 50
meters further down plunge from the last known stope.

Geological logging of the core identified predominantly massive quartz veining
with sphalerite, galena, pyrite and minor arsenopyrite.  The quartz reef has
a hanging wall contact marked by a laminated quartz vein and overall the lode
closely resembles the Ballarat mine reef system.

The hole ended in sandstone and not the expected black shale, and computer
modelling based upon detailed lithological core logging will assist in
determining where and at what depth the historically gold rich intersections
typically found within black shales may sit in the South Birthday Zone.

Berringa Syndicate Zone - Drillholes BE23002 & BE23003

Near the centre of the licence area, located approximately 1.5km north of
BE23D001, drilling at the Berringa Syndicate Zone, which historically produced
at 7-8 g/t, returned positive results including minor fine visible gold within
a well-defined lode structure.

This unmined zone was identified in the late 1980s from sampling in
underground drives and adits with BE23002 and BE23003 being the first
drillholes to test this zone. Downhole quartz vein intersections included
intervals of 9m and 14m with abundant quartz near the footwall and hanging
wall contact.

Kangaroo Zone - BE23004, BE23005 & BE23006

Located due east of the Berringa Syndicate Zone, the Kangaroo Zone was tested
by drillholes BE23D004,005 and 006. This underexplored lode system has no
surface expression.

Identification of a potential mineralised reef was made from an old plan map
of underground workings. Only a single crosscut pushed from the historical
Kangaroo mine towards the east which successfully intersected a mineralized
structure.  It is unclear if any stoping took place.

BE23004 and BE23005 drill tested the northern extension of the possible
structure with BE23004 potentially intersecting a cross-course fault which
appeared to have offset mineralisation.  BE23005 also pierced the cross
course in a different position but has struck part of a lode structure on the
north side of the fault. It is possible that the estimated location of the
underground workings was not yet exact so that drilling may have passed over
the top of the lode. Further geological work on the lithological core logging
will help to refine the positioning and identify optimal locations on the east
lode for future drilling.

Drillhole BE23006 exceeded expectations, intersecting a broad (over 30m
apparent width) mineralised quartz reef structure that had not been known
containing minor arsenopyrite, galena, sphalerite.  Visible gold was also
identified in the hanging wall contact. Initial interpretation suggests the
mineralised zone may be closer to the west than previously considered, and the
drilling may have intersected a saddle reef not previously mined.

This supports the inference of a second (parallel) line of mineralization to
the east of the main Berringa line and has substantially increased the
prospectivity of the Berringa property overall.

Next steps

The technical team is completing a detailed review of the drillhole data
including inputting all geological and structural data into 3D modelling
software. Next steps will be determined in due course and the market will then
be updated.
