Were the nature of the quality control
procedures adopted (e.g. standards, blanks,
duplicates, external laboratory checks) of
acceptable levels of accuracy (i.e. lack of
bias) and precision?
SAMREC-(Sect A:
Criteria 6)
SME-(Criteria B.3)
Yes, Item 14-15 and 16
LG, JFT
1.7
Verification of
sampling and
assaying
Was there verification of significant
intersections by either independent or
alternative company personnel?
Was there any use of twinned holes?

1.8
Location of
data points
Were accurate and quality surveys used to
locate drill holes (collar and down-hole
surveys), trenches, mine workings and other
locations used in Mineral Resource
estimation? (Includes the quality and
adequacy of topographic control.)
CIM-(43-101-Item
12)
JORC- (Sect A:
Criteria 8)
Yes, Item 13, the
topography surveys and
drillhole collars are
executed by surveyors.
Surveys (Reflex) are
performed by the dillng
contractor and
controlled by the
Geology Department.

SAMREC-(Sect A:
Criteria 8)
SME-(Criteria B.2)
1.9
Data spacing
and
distribution
Has the data spacing of exploration results
been denoted?
Is the data spacing and distribution sufficient
to establish the degree of geological and
grade continuity appropriate for the Mineral
Resource and Ore Reserve estimation
procedure(s) and classifications applied?
Has sample compositing been applied?
CIM- (43-101-Item
14)
JORC- (Sect A:
Criteria 9)
SAMREC-(Sect B:

Yes, Item 19
LG, JFT
1.10
Orientation of
data in
relation to
geological
structure
Does the orientation of sampling achieve
unbiased sampling of possible structures and
has the extent to which this is known been
denoted (considering the deposit type)?
[If the relationship between the drilling
orientation and the orientation of key
mineralized structures is considered to have
introduced a sampling bias, this should be
assessed and reported if material.]
CIM- (43-101-Items
13&14)
JORC- (Sect A:
Criteria 10)
SAMREC-(Sect B:
Criteria 5)
SME-(Criteria B.2)
Yes, Item9-13 and 19,
the data collect respect
the homogenety of the
ore body.
