Sampling · Sampling was via a reverse circulation

1
m samples weighing an average 3-4kg. Samples
were produced using a rig mounted cyclone
and riffle splitter for a ratio of
87.5%
to 12.5%. The majority of the samples were
recorded dry. All samples were sent to be
analysed
at ALS Laboratories in Townsville.

Drill · Recovery was visually estimated and
sample recorded. Recoveries are considered to be
recovery excellent averaging well over 90%,
generally 100%. Occasionally lower
recoveries were

· Every individual sample was collected into
the cyclone prior to riffle splitting.
Cyclone and sampling equipment was checked
and cleaned after each
rod.
· No significant changes in recoveries

status by Altona Mining

d.
· No joint ventures apply.
· There are agreements in place with the
native
t
itle holders, the Kalkadoon people and with
landholders.
· No significant historic sites or national
parks are located within the reported
exploration
sites.
· Both Mining Leases were granted in late
2012 and are in good
standing.
Exploration · CRA Exploration completed soil surveys, RC
done by drilling and mapping at Turkey Creek. Soil
other survey and mapping identified the
parties mineralisation but drilling failed to
intersect mineralisation due to the wrong
drilling
direction.
· Xstrata Exploration drilled two RC holes
at the southern portion of Turkey Creek in
2011 intersecting copper
mineralisation.
· Altona Mining followed with seven RC holes

ing the mineralisation some 400m to the north
· Minimal exploration work is known to have
been carried out at Green Hills. CRA
Exploration drilled one diamond hole
approximately 100 metre north of the holes
reported here with no significant results.
Geology · Mineralisation is considered to be
hydrothermal and structurally controlled
following internal competency, chemical and
permeability contrast typical to the
Roseby area metasediments.
· Mineralisation occurs both as fine grained
pervasive dissemination and coarse grained
vein hosted. Mineralisation is
sulphidic under shallow, approximately 25
metre, oxidised cap. Copper sulphides
include chalcocite, chalcopyrite and
bornite. Majority of the oxide
mineralisation consists of malachite but
significant amounts of cuprite have been
observed.
Drill hole · Collar locations, elevations, azimuth, dip
Information and
len
gths are presented in Table 2 of this
release.
· Down hole widths of the mineralisation are
presented in Table 1 of this
release.
Data · Intercepts were calculated using a 0.3%
aggregation copper cut-off typical to the Roseby area
methods mineralisation. A minimum of 4m intercepts
are reported here and a maximum of
consecutive
4
m of below 0.3% samples were allowed within e
ach
intercepts.
· No equivalent calculations have been
applied or
used.
Relationship· Drilling azimuth is considered to be
between approximately perpendicular to the strike
mineralisat of the mineralisation resulting unbiased
ion widths widths in east - west
and direction.
intercept
lengths · True widths of the intercepts vary
according to the varying dip of the
mineralisation and the dip of the
well-defined schist host
rock.
· Mineralisation dips at approximately 60
degrees to east for the majority of the
central portion. True widths are considered
to represent average of 90% of the down
hole intercepts. In the north and south
mineralisation dips to east at 70 and 80
degrees, respectively. True widths are
considered to represent average of 80% of
the down
