GOLDEN SUN PROVIDES CLARIFICATION ON ITS DISCLOSURE

As a result of a review by the British Columbia Securities Commission, Golden Sun Mining Corp. is issuing the following news release to clarify its disclosure.

Cherry Hill mine property, California

The company wishes to retract previous disclosure made in its corporate fact sheet dated Jan. 3, 2012, its corporate presentation dated March, 2013, and posted on its website regarding an estimated resource for its Cherry Hill gold mine as the company does not have a current resource.

The company treated the previously disclosed estimate to be a historical estimate, but failed to properly report it as such. The company's disclosure of the historical estimate was not suitable for public disclosure. In addition, it omitted critical information regarding the classification, tonnage and average grade of the resource; the source and date of the estimate; the relevance and reliability of the estimate, including key assumptions and parameters that were used; as well as appropriate cautionary language required by National Instrument 43-101 for all disclosure of historical estimates. In addition, this historical estimate should not have been disclosed to the public as the estimate cannot be considered equivalent to a current inferred resource as there were too many assumptions regarding the continuity of gold mineralization and the width of the vein. Specifically, projected continuations of the vein in the horizontal and vertical are based on information at too great of a spacing to create a reasonable level of confidence.

Investors are cautioned that they should not rely on any previous disclosure of a resource for its Cherry Hill property. In order to clarify the current status of the deposit, the company would like to reiterate that it does not have a current mineral resource of any type for the Cherry Hill property.

The company wishes to retract previous disclosure made in its March, 2013, corporate presentation, corporate fact sheet and website disclosing anticipated production costs, average grade and mine plan, as well as production rates and gross quarterly sales for its Cherry Hill gold mine as these disclosures were not supported by a preliminary economic assessment (PEA). The companion policy to NI 43-101 clarified that it is prohibited to disclose the results of an economic analysis, including a preliminary assessment, preliminary feasibility study and a feasibility study that includes inferred resources. As a result of there not being a mineral resource of any kind at Cherry Hill, any such disclosure cannot be made.

The company would like to reiterate that investors should not rely on any estimates previously made public by the company as the company does not have a PEA.

The company has removed from its website, corporate presentation and fact sheet all references to mineral resource estimates for its Cherry Hill property.

A report on the Cherry Hill property, authored by independent consultant Derrick Strickland, PGeo, a qualified person as defined by NI 43-101, was received by the company on May 22, 2012, and subsequently filed on SEDAR on June 8, 2012. An updated technical report on the Cherry Hill property has been commissioned by the company. It is expected that the updated report will be received by the company in approximately three weeks.

Clarification of sample results

The company wishes to clarify its news dated Jan. 12, 2012, in which the company released assay results from samples taken by an independent qualified person. The results from that news release are restated as follows:

"A total of six samples were collected in order to confirm that the Queen vein is gold bearing, and attempt to replicate published and unpublished assay data. The samples returned values ranging from 0.02 to 20.2 grams per tonne gold. As the Queen vein is relatively narrow (from one to 26 centimetres or 0.5 to 14 inches), the samples from the vein were taken along the length of the vein in order to sample as much of the vein as possible. For clarification, these samples were taken to confirm the presence of gold and not to be representative of particular random portions of the vein.

"Sample CH11-01 was taken at 400 feet of the (at the previous face) from banded quartz vein from the area of current production. The vein at this location is 10 centimetres wide; however, the sample was 40 centimetres along the length of the vein and returned a value of 12.4 grams per tonne gold. Sample CH11-02 was taken at the 340 feet of the main Q4 level from banded quartz vein. The vein at this location is 10 centimetres wide; however, the sample was 30 centimetres along the length of the vein and returned a value of 1.71 grams per tonne gold.

"Sample CH11-03 was taken in the Q4-1 raise, i-drift, which is the company's second active working, from banded quartz vein. The vein at this location is 13 centimetres wide; however, the sample was 30 centimetres along the length of the vein and returned a value of 20.2 grams per tonne gold.

"Sample CH11-04 was taken at 242 feet of the main Q4 level across a 20-centimetre-wide zone of fault gouge and returned 0.04 gram per tonne gold.

"Sample CH11-05 was taken at 150 feet of the main Q4 level, and was a grab sample of fault gouge and returned 0.24 gram per tonne gold.

"Sample CH11-06 was a grab sample from a muck pile in the Q4-1 raise consisting of wall rock (black slate with euhedral pyrite) and returned 0.02 gram per tonne gold.

"The independent qualified person was satisfied with the sample results as they confirmed the presence of gold in the Queen vein on the Q4 level. The samples were submitted to Acme Labs in Vancouver for assaying and gold was analyzed using a 30-gram fire assay. As there were only six samples taken, the sampler relied on Acme Lab's internal quality control procedures."

Non-compliant disclosure of exploration target

The company wishes to retract previous disclosure made in its corporate presentation inferring an exploration target at Cherry Hill.

The company does not have a reportable exploration target at Cherry Hill, and investors are cautioned that they should not rely on any previous disclosure of such estimates.

Disclosure of expected gold sales

The company wishes to clarify previous disclosure in its news releases dated Jan. 19, 2012, March 1, 2012, and Oct. 3, 2012, that disclosed the company anticipated selling mineral concentrates. The company had made this disclosure as to inform the public of the company's anticipated process once it had received a sufficient quantity of gravity and flotation concentrates.

The company is in possession of approximately seven tonnes of mineral concentrate being held in its secured storage facility in Yreka, Calif. As well, the contract mill in Oregon is holding an undetermined amount of gravity and flotation concentrates from the 740 tonnes processed. To date, the company has not sold any mineral concentrate or gold produced from Cherry Hill.

Other production-related disclosure

In its May 3, 2012, news release, the company disclosed plans to expand the main working with the goal to increase its mining rate subject to receiving proceeds of a financing. The company did not receive funds until October/November, 2012, which the company disclosed in a news release on Oct. 3, 2012, that trucking of mineralized material had begun. The company wishes to clarify that the planned expansion has not yet occurred. In its management's discussion and analysis for the nine-month period ended Jan. 31, 2013, the company disclosed that, on Oct. 25, 2012, the company entered into a contract for milling and paid the operators $60,000 as an advance for milling services. The company later learned that delays to the start of milling occurred as the mill required rehabilitation upon start-up.

During the mill processing, the operators of the mill did not provide the company with any results as requested. The company subsequently stopped trucking and milling at approximately 740 tonnes. The company had a representative on site for the beginning of the processing; however, after an unplanned shutdown that was scheduled for several days and resulted in the company's representative being away from the mill, a majority of the material was run through the mill without the company's representative being present.

Upon the threat of legal action, the contractors provided the company with results that did not equate to what the company felt was reasonably expected. The company's qualified person attended the mill after milling had stopped and took a number of samples for assaying. These samples proved that material from several locations in the mill that were considered as waste actually contained important gold values.

The company plans to pursue this matter through its legal counsel and will act accordingly upon its advice. The company had yet to provide an update regarding this as the company is still investigating its options and has yet to determine the best course of action to resolve this issue.

New acquisition property, California

On Sept. 6, 2012, the company announced that it had entered into an agreement in principle for the exclusive mining rights to a property located approximately 10 kilometres from the company's wholly owned Cherry Hill mine.

In that news release, the company had included historical assays. The company would like to restate that the assays are historic in nature and were not included in a technical report. Investors are cautioned as to the reliability of those assays as the width and locations of the samples were not provided to the company. As such, the company was not able to corroborate those specific results by sampling in the same locations.

The news release also stated that grab samples taken by the company were run at the company's on-site lab that was not ISO compliant. The results of those samples were not reported because results from the company's lab are not suitable for public disclosure as they do not get verified independently.

The company did not conclude the transaction on the property as concerns arose during the company's due diligence as to the status of the claims. The company did not make any payments.

Zacatecas properties, Mexico

The company wishes to retract previous disclosure made its March, 2013, corporate presentation for its Zacatecas project, located in Mexico, of a mineral resource for the mineralized historic dumps on surface as that disclosure was not compliant with NI 43-101 as it was not categorized per the CIM Definition Standards on Mineral Resources and Mineral Reserves, or was the grade or quality of the resources stated.

Investors are cautioned that they should not rely on any previous disclosure implying a resource for the Zacatecas properties. The company reiterates that it does not have any mineral resources defined at its Zacatecas properties and does not have an NI 43-101-compliant technical report that includes a resource estimate.

The company has removed from its website, corporate presentation and fact sheet all references to mineral resource estimates for its Zacatecas properties.

To further clarify its disclosure, the company wishes to restate its results for its phase three exploration program at Zacatecas completed in May, 2009.

The company completed a trenching program of 11 mineralized dumps located within the Salvador and Zacatecas properties. The dumps consist of visibly mineralized material that had been mined, in some cases, over 75 years ago, but was not considered economic at the time. The objective of the 2009 sampling program was to test the potential of the dumps by digging trenches across them that reached the bottom or original topography. The trenches were then sampled vertically at an average spacing of three metres along the length of the trench to maximize the representativeness of the sampling as historic dumps tend to be layered horizontally with lower and higher-grade material. A total of 74 samples were taken with gold values ranging from trace to 0.668 part per million and silver values ranging from 1.8 to 798 parts per million.

The attached tables show the weighted averages for the sampling of each mineralized dump.

The samples were submitted to ALS Chemex Labs in Mexico for assaying with gold being analyzed using a 30-gram fire assay and silver by ICP with an AA finish. Standards and blanks were inserted in series as every 10th sample during the sampling process, resulting in approximately 5 per cent of all samples being used for quality assurance/quality control.

Yoreme property, Mexico

The company wishes to restate its previous disclosure made in a news release dated May 3, 2012, regarding exploration results from its Yoreme project, located in Mexico, as the assays reported were not balanced and did not provide a level of detail as required under NI 43-101.

Fieldwork at Yoreme was successful in delineating potential extensions of the San Manuel and prospection located an additional series of subparallel veins located near the centre of the property.

A trenching and sampling program totalling 39 samples from six trenches, three chip channel lines and four grabs was completed in order to test for splays off of the main trend and sample newly identified historic workings along the San Manuel vien. Chip channel and trench samples ranged from 0.4 to 5.2 metres in width and the results ranged from below detection to 459.7 parts per million silver. No significant gold values were encountered. The trenches did not uncover any significant mineralization; however, sampling at the openings of historic workings in the southern portion of the San Manuel vein returned favourable results that are summarized in the attached table.

Two soil grids were sampled over the northern and southern extents of the San Manuel vein with each grid showing multielement anomalies along strike of the known extent of the vein. These results indicate that the strike length of the San Manuel vein could be as much as one kilometre, which is approximately 30 per cent more than the current known strike length.

In addition, the field program included a 13-line-kilometre induced polarization geophysical survey. This survey was successful in identifying an approximately 300-metre-by-400-metre chargeability anomaly located immediately to southwest of the San Manuel vein, as well as a linear anomaly near the centre of the property.

Follow-up fieldwork has yet to determine the cause of the larger anomaly; however, work in the immediate vicinity of the linear anomaly resulted in the discovery of at least three subparallel veins. These new veins are hosted within the intrusive, which is different to the San Manuel vein that is located within the contact between the intrusive and volcanic rocks.

The rock and soil samples were sent to Inspectorate Labs in Hermosillo and were accompanied with seven standards and 10 blanks as part of the company's quality assurance/quality control procedures, with results returning values within acceptable parameters. The samples are inserted in series with the original samples as to represent approximately 5 per cent of all samples submitted to the lab.
