Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts the responsibility for the adequacy or accuracy of this release.

Implats welcomes the call by Cosatu to strikers to return to work, and the plea for calm by the SA Communist Party which expressed concern about the violence.

During the NUM’s mass meeting on Tuesday at Implats’ Rustenburg mine, a few statements were made which are inaccurate and of grave concern to management.  Implats is urgently consulting the NUM leadership and is hoping to convene a meeting to discuss the matter as soon as possible.  Until this meeting has been held, we would prefer not to discuss the issue in the media. 

Remuneration issues

No formal wage demands have been tabled by the NUM, but there seems to be misinformation and confusion relating to remuneration packages and in response to many questions in this regard, Implats would like to provide the following information.

Miners are a skilled category on the same level as artisans.  They have blasting certificates which puts them in a position of responsibility and supervision with authority over other workers. This position also carries with it a legal appointment with clear legal responsibilities. 

Implats has had discussions with the NUM over a long period of time regarding the high turnover (average of 25% per annum) of these employees in the past 2 – 3 years.  The contributing factors include the fact that their reward has become out-of-line with the rest of the industry. Implats’ reward policy is to position our wages and salaries within 10% of the sector benchmarks, but the miner category has been one in which we have been substantially below the benchmark for a number of years.

After consultation with the NUM during November/December 2011, a salary increase and a housing allowance increase for the miners was debated, agreed and implemented in consultation with the NUM in January 2012. 

All salaries in the bargaining unit are rigorously negotiated with the NUM who represent the majority of the workers and these salaries form part of signed and binding agreements.  At no stage are any collective increases implemented without due process and consultation with the NUM.

Vancouver, British Columbia, February 21, 2012 - Rye Patch Gold Corp (TSX.V: RPM; OTCQX: RPMGF) (“Rye Patch” or the “Company”) is pleased to announce an update on the Company’s 100% owned Garden Gate Pass project located along the Cortez trend - one of Nevada’s most prolific gold trends.

Highlights:

·         Barrick Gold has connected the Red Hill and Goldrush deposits and doubled the gold resource from their September 6, 2011 announcement;

·         The gold trend has 8 kilometres of gold deposits starting from the Horse Canyon mine to the ET Blue gold deposit and remains open toward the Garden Gate Pass project;

·         Rye Patch’s 2011 drilling campaign intersected lower plate lithologies in 4 of 6 drillholes, and encountered thick zones of Carlin-style alteration with geochemically anomalous gold and pathfinder elements; and

·         Using the data points generated from the 2011 drill program, Rye Patch is refining its drill targets and plans to commence drilling in May 2012 pending drill rig availability.

On February 16, 2012, Barrick announced a new resource on their Red Hill and Goldrush complex of 1.3Mozs gold in the indicated category, and 5.7Mozs gold in the inferred category.  The new resource doubles the resource previously announced on September 6, 2011, and shows the immense potential of the district.   Barrick’s drilling along the north-south trend has connected the two discoveries and indicates the gold zone is open in multiple directions including toward the Garden Gate Pass project.

“Barrick’s recent summary of the Goldrush and Red Hills gold complex shows the gold system is extremely strong with robust gold grades and gold intercepts immediately north of the Company’s Garden Gate Pass project.  Rye Patch’s 2011 drill program confirmed the presence of lower-plate host lithologies along with thick alteration zones with geochemically anomalous gold and known Carlin-style pathfinder elements.  A refinement of the target areas using the drillhole information and re-processing our gravity and magnetic geophysical surveys will provide better resolution on the target areas for the next round of drilling” stated William C. Howald, President and CEO of Rye Patch Gold.

Using the depth to lithology, structure and alteration in the six drillholes completed in 2011, Rye Patch’s contract geophysicist, Terry White, will constrain the geophysical gravity and magnetic models to honor the recently acquired sub-surface information.  The new constrained models will better define the gold trend and depth to the permissive lower-plate lithologies.  This iteration process is required for projects with pediment gravels or cover rocks above the ore zones.  The Garden Gate Pass project lies within a gravel covered valley.  The claims cover an area of 13 square kilometres immediately adjacent to Barrick’s newly discovered Goldrush and Red Hill gold deposit complex.  Drill results to date indicate the project is along a major gold trend with significant upside potential that will be addressed in the upcoming drill program.

The size of the summer drill program has not yet been determined but will employ a combination of reverse circulation pre-collars with core tails.   This drill methodology will give the geologic team a better understanding of the host rock lithologies, structure and potential ore zones.   A budget of $1,000,000 is proposed.

Mr. William Howald, AIPG Certified Professional Geologist #11041, Rye Patch Gold's CEO and President, is a Qualified Person as defined under National Instrument 43-101.  He has verified the information contained in, and has reviewed and approved the contents of, this news release.

Highlights:

·         Indicated resources in the primary zone are 1.8 million tonnes averaging  10.05% zinc, 3.31 g/t gold, 1.78% copper and 115g/t silver

·         Total contained metals  in the Indicated categories at Adi Nefas are estimated as:

o   408.0 million pounds of zinc 

o   72.2 million pounds of copper

o   196,000 ounces of gold

o   6.81 million ounces of silver

Note: Contained metal calculations are as follows: copper and zinc: tonnes x grade (%) x 2204.622. Gold and silver: tonnes x grade (g/t) ÷ 31.10348. Results were rounded and no allowance was made for mining dilution or metal losses in the recovery process.

Sunridge President and CEO Michael Hopley says, “The average grade of all metals in the Adi Nefas deposit has significantly increased in this new resource estimate compared to the previous estimate in 2008.This high-grade material should enhance the economics of the Asmara Project when this material is mined and blended as a high-grade feed to a central North Asmara processing plant in conjunction with the nearby Emba Derho deposit as well as the sulphide material from the Debarwa deposit. We expect that most of these resources will be converted to reserves with the completion of the pre-feasibility study in April.”

Note: Resource and contained metal estimates are rounded and remain subject to factors such as mining dilution and process recovery losses.

NOTES

This new Adi Nefas resource estimate, completed by Snowden, is as of February 20, 2012 and complies with the CIM Definition Standards on Mineral Resources and Mineral Reserves, as required by National Instrument 43-101. Resource modeling and grade estimation was undertaken by Snowden and reviewed by Andrew F. Ross, FAusIMM (CP Geo), P.Geo (APEGBC #145711)(Senior Principal, Snowden), a Qualified Person as defined by NI 43-101, based on geological interpretations and a drill database (current to August 2011) provided by Sunridge. The database and the Sunridge sampling and assaying QA/QC procedures and results were reviewed by Snowden. Further details of the estimation procedure will be available in the NI-43-101 report which will be posted on the Company’s profile on SEDAR (http://www.sedar.com) no later than 45 days from the date of this press release.

GEOLOGICAL BACKGROUND

The Adi Nefas deposit occurs as a prominent outcropping gossan at surface that is the expression of deeper volcanogenic massive sulphide (VMS) mineralization.  The gossan is traceable over a strike length of 700 metres and is north-northeast trending.  The deposit is a steeply east dipping massive sulphide layer that is hosted within a sequence of felsic meta-volcanic and meta-sedimentary rocks.  The massive sulphide layer has an average width of 6 m to 12 m and is largely hosted within a hydrothermally altered felsic quartz-sericite-chlorite pyrite schist which is flanked in the hanging wall and footwall by altered meta-basaltic rocks.  The deposit is partitioned into upper oxide and transition zones with precious metal enrichment and base metal depletion, underlain by a zinc and copper rich supergene zone, and a lower primary zinc-rich sulphide zone.

The primary zone is typically developed beyond a depth of 40 metres from surface and is the focus of the prefeasibility study. The primary zone includes a unit of low grade chert and exhalite which has been modeled separately to the massive sulphides.  Previous mineral resource estimates did not partition this rock unit from the massive sulphides and as a result were lower grade and higher tonnage than the current estimate.

METHODOLOGY

The mineralization on which this new Adi Nefas resource estimate is based extends over a strike length of 455 metres and a width of up to 12 metres and has been drilled to a maximum vertical depth from surface of approximately 400 metres. The deposit has been explored using 101 exploration drill holes and 8 geotechnical drill holes.   70 drill holes encountered mineralization and assays of split core have been used in this estimation of resources.

The interpretations of mineralized zones were modeled using three-dimensional wireframing techniques based on a distribution of drill intersections ranging from less than 25 metre to up to 135 metre spacings on 40 metre drill section intervals. The wireframe interpretations formed the basis for the construction of a block model as well as the constraining of samples for geostatistical analysis and grade estimation. A block model was constructed in Datamine mining software with a parent cell dimension of 7.5 m (X) x 10 m (Y) x 5 m (Z) subcelled to 0.5 m x 5 m  x 2.5 m (XYZ) for accurate coding with the wireframe interpretations.

Grades for copper, zinc, gold, silver, lead and iron were estimated within primary and weathered horizon control using Ordinary Kriging after compositing the assay intervals to 1.5 m down-hole lengths. Search ellipsoid dimensions and orientations were determined on structural geological and geostatistical information. Density values were calculated for blocks based on regression formulae for iron, copper, zinc and lead estimates. 

The interpreted mineralized zones were categorized for resource classification as Indicated or Inferred in a series of steps. Each zone was reviewed in the context of the spatial distribution of drill intersections used to model and estimate grades for that zone, with due consideration for the known geological and geostatistical continuities and confidences in the base data and geological interpretations. On this basis the relatively densely drilled (40 m section spacing) primary zone received Indicated status.

Michael Hopley, President and CEO of Sunridge Gold Corp. is the Qualified Person responsible for the contents of this press release and has reviewed the information in the release and confirmed that it is consistent with that provided by the independent Qualified Person responsible for the resource estimate, Andrew F. Ross of Snowden.
