Diamond drillholes confirm high silver grades at Webb Silver Project

Results from remaining diamond drill infill holes (DDH) have confirmed and locally upgraded previous high grade
intersections from reverse circulation (RC) drilling at the Webbs Silver project in New South Wales. The DDH program
completed late last year will assist with geological interpretation of the deposit and provide drill core samples for
metallurgical test work.

The results again demonstrate the near surface nature and high grade character of mineralization at Webbs. The latest
results have not been incorporated in the 400% upgrade of the Indicated and Measured JORC resources at Webbs, as
announced on February 27.

Detailed results from the latest holes are presented in Table 1. Highlights include:

    -       DDH026 intersected:
        
                        * 6.45m @ 200g/t Ag, 0.33% Cu, 1.57%Pb and 1.23% Zn from 49.25m;
                            
                        Incl. 2.00m @ 365g/t Ag, 0.62% Cu, 2.40% Pb and 2.47% Zn from 52.65m

    -       DDH027 intersected:
        
                        * 5.15m @ 398g/t Ag, 0.66% Cu, 3.19% Pb and 2.1% Zn from 34.1m;
                            
                        Incl. 1.00m @ 708g/t Ag, 1.26% Cu, 2.92% Pb and 1.45% Zn from 34.1m

    -       DDH030 intersected:
        
                        * 7.80m @ 464g/t Ag, 0.78% Cu, 2.17% Pb and 1.69% Zn from 29.8m;
                            
                        Incl. 2.60m @ 1125g/t Ag, 1.81% Cu, 3.79% Pb and 2.94% Zn from 30.9m


Silver Mines CEO Charles Straw stated "the near surface high grade silver results, along with impressive grades of
copper, lead and zinc continues to demonstrate the presence of shallow, high grade mineralisation at Webbs".

"The next phase of drilling will target an additional 200m of vertical depth and target mineralisation up to 330m below
the surface.  Drilling will also target extensions to Webbs Main and Webbs South, where near surface potential exists
along strike."

"Based upon the results of our exploration to date the Company remains very confident that the next round of drilling
has the potential to contribute towards a significant resource increase that will add a further allure to the Webbs
Silver Project."

Results

DDH026 and 27

Diamond drill holes (DDH026 and 027) were drilled in opposite directions on the same cross section. These holes were
designed to assist with detailed geological interpretation, confirm previous RC intersections and provide core for
metallurgical testwork. In line with previous RC intersections both diamond holes confirmed the lode horizon is
approximately 3.1m wide with average grades over that width ranging from 200-400g/t Ag (see Figure 1). Copper, lead and
zinc grades also show good agreement with surrounding RC holes.

DDH030

Diamond drillhole DDH030 was drilled about 25m south of DDH026 and 027. DDH030 intersected 7.8m @ 464g/t Ag. This
corresponds to a true lode width of about 2.1m. This compares moderately well to the nearby RC holes 092 and 260.
However, average grades in these RC holes are 188 and 281g/t Ag respectively somewhat lower than those from DDH030. A
narrower higher grade zone in DDH030 of 2.55m @ 1125g/t Ag, 1.81% Cu, 3.79% Pb and 2.94% Zn from 30.9m indicates much
higher grades than adjacent RC holes. This zone in DDH030 is shown in Figure 2.

Other Holes

DDH's 028 and 031 were abandoned and did not intersect the lode zone, although narrow low grade intersections were
recorded in subsidiary lodes as shown in Table 1. DDH029 was collared so as to just miss the Main lode horizon. However
it did intersect the Western lode which returned an intersection of 0.85m @ 496g/t Ag, 0.75% Cu, 5.00% Pb and 3.37% Zn.

Future Plans

Results from these diamond holes will be incorporated into the resource database as they were not included in the recent
resource upgrade. Drill core from these holes has been dispatched for mineragraphic examination which will assist
metallurgical evaluation and samples have been selected for metallurgical test work.

A new round of drilling is scheduled to begin in April 2012. The primary objective of this drilling will be to grow the
overall resource inventory. The upcoming program will focus on additional deeper and extensional target areas where the
deposit remains open along strike to the south and down plunge at Webbs Main and Webbs South.

These targets are considered high priority as some of the widest and highest grade intercepts are still open at
relatively shallow depth of approximately 80-140m below surface. Silver Mines has already pre-paid for 6000m of RC
drilling at competitive rates.

The Company looks forward to reporting results from the new drilling program in the coming months.

All co-ordinates are in MGA grid. Drill hole elevations all around 712m ASL +/-3.5m.

# 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 in holes with dips of -55 degrees and
approximately 33% of down-hole intervals in holes with dips of -70 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.
