Silver Mines Limited (ASX:SVL, PLUS:SVLP) is pleased to announce results for a further two diamond drill
holes (DDH) completed at the Webbs Silver project. These DDH holes were designed to infill the previous
reverse circulation (RC) drill pattern, twin RC holes in order to assist in geological interpretation and
test deeper targets. Results and drillhole details are presented in Table 1. Drill core samples will also
be used for metallurgical testwork.


Silver Mines CEO Charles Straw stated "the intersection in drillhole DDH017 in particular is some of the
deepest mineralisation discovered at Webbs so far by Silver Mines and demonstrates the excellent potential
in the deposit which boasts some of the broadest and highest grade silver intersections of any primary
silver project in the country at present. The width and grade of this zone at Webbs South represents an
excellent target for deeper drilling and the deposit still remains open at depth here and in many other
locations. "



Diamond Drilling

DDH017

DDH017 was drilled towards the southern end of the Webbs South prospect. The hole was designed to test for
depth extensions of mineralisation intersected in adjacent holes. DDH017 intersected the lode approximately
15m down dip of the high grade intersection in RC076 (see Figure 1). RC076 returned 25m @ 1175g/t Ag
including 11m 2264g/t Ag. DDH017 returned an intersection of 25.9m @ 337g/t Ag including 9m @ 686g/t Ag.
Both holes also have appreciable levels of Cu and Zn.

DDH017 confirms the width of the mineralised-altered zone intersected in RC076. The true thickness of the
mineralised zone in this area is around 11m, with narrower zones of higher grade around 4-5m wide. The
differences in grade between RC076 and DDH017 are likely due to natural variation as the distance between
the two holes is probably too great for direct comparison. The mineralised zone remains open below DDH017
and the width and grade intersected represent a very attractive target for future drilling as shown in
Figure 1. Drillhole RCD129 (RC pre-collar with diamond tail) was aimed to test this target at depth.
However, the hole deviated and had to be abandoned.


DDH018

DDH018 was drilled as an infill/confirmation hole at the northern end of the Webbs South prospect.
DDH018 intersected the mineralized lode very near RC135. Using a 40g/t Ag lower cut-off, the mineralized
intersections in both holes indicate the lode to be approximately 3.2m wide with average grades of
around 415g/t Ag over that width.


Future Plans

The updated resource estimate for the Webbs deposit is still in preparation. The company awaits further
assay results for diamond drill holes to be included in the resource estimate. Accordingly the resource
estimate will be released once the new results have been incorporated into the resource database.

Drill core is also being used to formulate metallurgical samples upon which additional metallurgical
testwork will be conducted to pre-feasibility level. This work will include flotation testwork and
additional testwork on pre-treatment of concentrate and cyanide leaching of silver.

Additional drilling at Webbs is planned in early 2012 in order to expand the resource base. This drilling
will test deeper high grade targets as well as several near surface gaps in the existing drill pattern.

# Down-hole intersections are NOT true widths due to the geometry of the lodes and angle of intersection of
the drill hole. True widths are estimated to be approximately 45% of down-hole interval for holes with dips
of -55 degrees.

Sampling and Assaying

HQ diamond core samples are cut lengthways to produce half core. Samples are usually taken at 1m intervals
or as geology dictates.  Silver Mines have opted to utilise the services of ALS-Chemex (Brisbane), a
globally respected company servicing the mining industry. Samples are dispatched by TNT Couriers from Glen
Innes to ALS. Core is crushed to -6mm and a 1kg split is then pulverised to provide the assay pulp. Routine
assaying is conducted by ALS Method ICP41 This is acid digest with an ICP-AES finish analysing for Ag, As,
Bi, Cu, Fe, Pb, S, Sb, Sn, W and Zn. When elements exceed upper detections limits of 100ppm for Ag and 1%
for Cu, Pb and Zn they are reanalysed by and appropriate ore grade acid technique (ALS method OG46). For
silver above 1500g/t a gravimetric technique is used. Certified Standards and blanks are routinely
submitted in each assay batch to monitor QA-QC.
