Sona Resources Clarifies Technical Disclosure

Sona Resources Corp. (the "Company" or "Sona") (TSX VENTURE:SYS)(FRANKFURT:QS7)
announces that as a result of a review by the British Columbia Securities
Commission, the Company is issuing the following news release to clarify
disclosure issues. Investor presentations and management interviews on the
Company's website have been removed, pending modification, to comply with
National Instrument 43-101 ("NI 43-101").


Clarification regarding preliminary assessment

The PowerPoint presentation dated March 14, 2011, previously posted on the
Company's website, outlined the basic assumptions of the Micon International
Limited ("Micon") Preliminary Assessment ("PA") base case at 200 tonnes mill
throughput per day, dated June 10, 2010 (news releases dated May 18, 2010, and
June 22, 2010). The Company based this figure on the available Indicated and
Inferred resources at the Blackdome Gold Mine ("Blackdome"), and Inferred
resources from the Elizabeth Gold Deposit ("Elizabeth"), as supported by a NI
43-101 Technical Report dated July 22, 2009 (news releases dated June 8, 2009,
and Sept. 10, 2009). However, the PowerPoint presentation also contained a table
comparing the economic parameters of the Micon PA base case, which used a gold
price of $950 per ounce, to a sensitivity of the base case using $1,350 per
ounce. The only parameter changed was the price of gold, which was input by the
Company into the Micon spreadsheet analysis. The sensitivity analysis was not
titled "Sensitivity" and could be construed as a new or improved economic
analysis, which is not the case and should not be interpreted as such. The
Company did not intend the $1,350 sensitivity to represent a new economic
analysis, and the Company retracts it and the resulting economic parameters.


The March 14, 2011, PowerPoint also projected eight-year estimated revenue and
economic parameters based on a $1,350 per ounce gold price and 300 tonnes per
day throughput, the upper capacity of the Blackdome Mill. However, NI 43-101
prohibits disclosure of these results, because the analysis assumed additional
quantities of resources not outlined in the Company's current resource
estimates. The Company retracts the resulting economic parameters.


In the event that the Company receives an increased resource estimate or an
updated PA that constitutes a material change in its affairs since the Micon
report, it will make a prompt announcement and file a supporting Technical
Report, as required by NI 43-101.


Results of the Micon PA

The details of the Micon preliminary assessment base case first announced on May
18, 2010, are reproduced here for clarity. They included the following summary:


"The economic review contemplates underground mining at Blackdome and Elizabeth
with a 200 tonne per day mill throughput over an eight-year mine life, to
recover 183,600 ounces of gold and 62,500 ounces of silver. Operating cash costs
are projected to average $686 per ounce or $208 per tonne milled over the life
of the project. Pre-production capital costs at Blackdome and Elizabeth are
estimated at $11.4 million and $9.4 million, respectively, with a combined
sustaining capital of $9.45 million. The pre-tax cash flow is estimated to be a
positive $27 million, and the after-tax cash flow $20 million."


At US$950 per ounce of gold, US$15 per ounce of silver, and a 1.08 Canadian to
U.S. dollar exchange rate, pre-tax net present value (NPV) of $11,459,000 at a
10 percent discount rate, generating an internal rate of return (IRR) of 31
percent. The PA was based predominantly on Inferred resources, and the
assumptions for the assessment are further presented in the news release dated
May 18, 2010, and in the Technical Report filed on SEDAR.


Cautionary language required for PA

Some prior corporate disclosure of the Micon PA results omitted mandatory
cautionary language required by NI 43-101. The Company clarifies that its PA is
preliminary in nature; it includes Inferred mineral resources considered too
speculative geologically to have the economic considerations applied to them
that would enable them to be categorized as mineral reserves; and that there is
no certainty that the preliminary assessment will be realized. Investors are
cautioned that any disclosure of the Company's PA should have included this
cautionary language and should be interpreted with such language in mind.


Potential exploration targets

The Company made various statements about exploration potential at the Blackdome
and Elizabeth properties in its PowerPoint presentation, the corporate fact
sheet, and its audio and video presentations previously posted on its website.
Statements of potential quantity and grade were not expressed as ranges as
required by NI 43-101, did not disclose the basis on which quantities were
determined, omitted grade, and did not include required cautionary language. The
Company's Qualified Person has reviewed geological and exploration information
relevant to estimates of potential. Based on this review, the Company restates
the potential mineral deposits targeted by its exploration programs at Elizabeth
and Blackdome as follows.


At Blackdome, exploration potential exists in several near-parallel quartz
veins, where gold values require follow-up. A target with particularly good
potential is the extension of the Giant Vein on the property. The additional
work planned over the next two years targets a potential mineral deposit of
between 250,000 and 400,000 tonnes, grading between 9.0 and 12.0g Au/t and
potentially containing 70,000 to 150,000 ounces of gold.


The Company also wishes to clarify the disclosure of additional potential
exploration targets on the Elizabeth Gold Deposit property. The Indicated
mineral resource estimate by SRK Consulting (Canada) Inc. ("SRK"), (news release
June 8, 2009), does not include results from the 25 additional holes, totalling
3,779 metres, drilled in the summer of 2010, principally into the Southwest Vein
on the Elizabeth property. The holes were partly for infill and partly step out,
particularly to the southwest over an additional strike length of approximately
100 metres and open to the southwest. The last three holes on a cross-section in
a southwesterly direction assayed 109.5g Au/t over a 2.5-metre core length
(E10-67); 20g Au/t over 1.0 metre (E04-11a); and 77.9g Au/t over 5.1 metres
(E10-69). The three intersections occurred over a vertical interval of
approximately 50 metres, centred at a depth of approximately 75 metres.
Mineralization at the Elizabeth zones has never been drilled below approximately
200 metres. In the Company's Management opinion, good potential remains on the
Southwest Vein, both along strike and at depth.


As well, mineralization on the No. 9 Vein has not been included in the SRK
Inferred resource estimate, and to date the Company has done little work in the
area and has not verified the gold values cited.


On the Elizabeth property, there are six known northeast-southwesterly trending
veins located over 700 metres, drawn at right angles to the southwesterly strike
of the veins. The Elizabeth veins occur at approximately 2,300 metres above sea
level, dipping approximately 80 to 85 degrees into the mountain, with a slope of
approximately 30 degrees, and are mostly covered with talus. In places, the
veins are difficult to drill from surface, outcrop is scarce, and their absolute
location may be in doubt.


The on-strike and dip extensions of both veins that host known gold
mineralization have not been tested and could potentially host additional gold
mineralization. The remainder of these veins and the other four known veins have
yet to be drill tested.


For the reasons summarized above, the Company's Management is of the opinion
that additional potential mineral deposits exist on the Elizabeth property.
Future exploration programs will target potential mineral deposits of one to two
million tonnes grading 9.0g Au/t to 12.0g Au/t, and potentially containing
260,000 to 770,000 ounces of gold.


Investors are cautioned that the potential quantity and grade of the material
over and above the known mineral resources for both the Blackdome and Elizabeth
properties are considered to be conceptual in nature; there has been
insufficient exploration to define a mineral resource; and it is uncertain
whether further exploration will result in the target being delineated as a
mineral resource.

The Elizabeth Gold Deposit mineral resource was estimated by SRK using a    
cut-off grade of 5.0g Au/t and a minimum width of 1.5 meters (news release  
dated June 8, 2009).                                                        



Mineral resources are not mineral reserves and have demonstrated no economic
viability. All figures are rounded to reflect the relative accuracy of the
estimate. SRK has reported the resources at a cut-off grade of 5.0g Au/t,
assuming an underground mining scenario and 100 percent metallurgical recovery.
