Vancouver, British Columbia, February 4, 2010: Golden Predator Royalty & Development Corp. (Golden Predator) (TSX:GPD), Strategic Metals Ltd. (Strategic) (TSX-V:SMD), Rockhaven Resources Ltd. (Rockhaven) (TSX-V:RK) and Platoro West Holdings Inc. (Platoro) (CNSX: PWH) are pleased to announce that they have executed a letter of intent pursuant to which Golden Predator, Strategic and Rockhaven will contribute an industry-leading portfolio of silver assets into Platoro, which will be renamed Silver Predator Mines Inc. ("Silver Predator"). The companies are also pleased to announce that Louis A. Lepry, Jr. has agreed to serve as Silver Predator's President & CEO.

Management of Golden Predator, Strategic and Rockhaven have identified that their silver assets are undervalued or unrecognized by the market, and are forming Silver Predator to realize on the value of these assets by creating a premier silver exploration and development company with its principal projects located in two of the top mining jurisdictions in the world: Nevada and the Yukon. The first world advantages of infrastructure, rule of law and political certainty, coupled with the outstanding mineral potential of these two principal jurisdictions, positions Silver Predator as a unique investment in its class.

Mr. Lepry brings a wealth of experience to Silver Predator, having spent the past 7 years with Newcrest Resources the Americas, a subsidiary of Newcrest Mining Ltd., and serving as President of Metallica Resources Inc. from 1995 to 2000. Mr. Lepry's responsibilities at Newcrest included identifying and recommending precious metal acquisition opportunities. At Metallica, Mr. Lepry was responsible for bringing the Cerro San Pedro gold-silver deposit in central Mexico from drill-out, through feasibility, to securing a joint venture partner for eventual mine construction. Prior to this, Mr. Lepry was Vice President - Corporate Development for Crown Resources Corp. and was instrumental in acquiring the South American precious and base metal asset-base which formed the core holdings of Crown's spin-off company Solitario Resources Corporation.

Silver Predator Property Portfolio

Golden Predator, Strategic and Rockhaven propose to contribute a total of 21 advanced stage and development properties, comprising over 39,000 hectares of land, to Silver Predator with Golden Predator's Taylor Property, Strategic's Blue Heaven and Quarterback Properties and Rockhaven's Plata Property being the most advanced.

Golden Predator Properties

The properties to be contributed by Golden Predator include the Taylor, Silver Bow, and Treasure Hill projects in Nevada, the Guijoso and Magistral properties in Mexico, as well as a Joint Venture Option Agreement on Golden Predator's 1,200 tonne (1,320 ton) per day Taylor Mill facility.

Taylor Project

The 100% owned Taylor Project is located in White Pine County, Nevada, 24 km (15 miles) south of the town of Ely and 6.5 km (4 miles) east of US highway 50. The property consists of 281 unpatented claims and four patented lode claims totaling approximately 1,692 hectares (4,180 acres). The claims are located in White Pine County within the Humboldt Toiyabe National Forest. Of the 281 claims, 50 are subject to a reserved 1% NSR. The resource described below is not located on these claims.

The Taylor Project is the subject of a NI 43-101 compliant technical report and mineral resource estimate dated January 19, 2009 by Michael G. Hester, FAusIMM of Independent Mining Consultants, Inc. A copy of the report on the Taylor Project is available on Golden Predator's website.

The Taylor Silver Deposit is an epithermal, high-silica, low-sulfide replacement deposit in Devonian carbonate rocks. The deposit occurs as argentiferous jasperoid replacement bodies in the upper Guilmette Limestone. These jasperoid bodies are localized by a combination of steep structural conduits and damming effects of overlying shale units. The mineralizing fluids traveled upward along the near vertical fracture zones to the crest of an antiform. Here, the fluids brecciated and replaced limestones with silica, barite, sulfides and other minerals including argentiferous sulfosalts. The antiform, which is a broad south-plunging structure, is centered on the Bishop Pit. The structural controls resulted in the jasperoid forming large, relatively flat, tabular bodies. Elsewhere on the property, mineralization occurs in the silicified portions of the Chainman shale and along previously mentioned north-northwest trending structures as well as in jasperoids and silicified structures cropping out in the overlying Joanna limestone. The highest silver assays within the surface mined areas are near apparent structures (feeders). Silver assays above one ounce per ton form a blanket at the top of the Guilmette Limestone that averages about 15 m (50 ft) thick over the axis and flanks of the anticline and covers an area of approximately 16 hectares (40 acres).

Mineral Resource

The current NI 43-101 compliant mineral resource for the Taylor Project was developed by Independent Mining Consultants during 2007. It was based on resources that might be extracted with the continuation of open pit mining, and did not contemplate potential underground mining scenarios. The resource estimate was based upon 29,300 m (96,118 ft) of drilling from 526 holes, including 111 holes drilled in late 2006 and early 2007. Of these 108 were reverse circulation and three were core holes drilled for metallurgical testing purposes. All drill holes within the resource area were vertical and indicated the true thickness of the bedded deposit. The Hester Report did not include 17 holes for which assays had not been received at the time of the report, nor did it include the 2009 recent drilling discussed below.

Measured and indicated resources at Taylor are 5,835 ktonnes at 79.2 gpt for 422.4 million contained grams (6,433 ktons at 2.31 opt for 14.9 million contained ounces) of silver. This consists of 1,123 ktonnes measured at 85.7 gpt for 87.741 million contained grams (1,238 ktons at 2.5 opt for 3.095 million contained ounces) of silver and 4,713 ktonnes indicated at 77.8 gpt for 334.325 million contained grams (5,195 ktons at 2.27 opt for 11.793 million contained ounces) of silver

Inferred resources are an additional 686.7 ktonnes at 87.1 gpt for 59.1 million contained grams (757 ktons at 2.54 opt for 1.9 million contained ounces) of silver.

Further Drilling

Subsequent to the date of the Hester Report Golden Predator drilled 11 angle RC holes for a total of 1,400 m (4,595 ft). This drilling was designed to test over 610 m (2,000 ft) along a higher grade structural corridor linking the historic underground workings and the bulk tonnage deposit. Results of this drilling indicated potential to extend the existing 43-101 compliant resource along the high grade structural corridor, and also demonstrated potential to increase grade within the existing resource by better defining the location and geometry of the structural feeder within the known deposit. Select intervals include holes GPT 002 with 5.8 m of 236 gpt (19 ft of 6.88 opt) silver, GPT 005 with 15.25 m of 164.5 gpt (50 ft of 4.8 opt) silver, GPT 006 with 13.7 of 147 gpt (45 ft of 4.29 opt) silver, GPT 008 with 16.7 m of 196.8 gpt (55 ft of 5.74 opt) silver, and GPT 010 with 12.2 m of 129 gpt (40 ft of 3.76 opt) silver.

Silver Bow Project

The Silver Bow Project is located 80.5 km (50 Miles) east south east of Tonopah, Nevada and contains 73 unpatented claims totaling approximately 591 hectares (1,460 acres). The property has seen historical production from narrow high grade veins of an estimated 311,000 grams (10,000 oz) Au and 3.1 million grams (100,000 oz) silver. The property is located in the Tonopah Trend of the Walker Lane Structural Zone. Mineralization consisting primarily of Stephanite, Pyrargyrite, Cerargyrite, and Electrum in a quartz calcite gangue is hosted in steep veins cutting Miocene tuffs. These exposed veins are interpreted to represent upper levels of Bonanza Epithermal gold/silver Vein Deposits. Approximately 50 holes have been drilled across the property by a number of operators. Over 10 miles of vein strike is exposed on the property. The Silver Bow property is subject to a 3% NSR, of which 2% can be purchased for USD $1,500,000.

Treasure Hill Project

Golden Predator has the exclusive right to explore, and the option to purchase a 100% interest in, the Treasure Hill/Mt. Hamilton polymetallic property located in White Pine County, Nevada, comprised of 190 unpatented claims, 106 patented claims and approximately 121.4 hectares (300 acres) of patented lands. In 2008, Golden Predator initiated historic data scanning and compilation along with preliminary field investigations on the property. Recommendations for further analysis of certain areas and the initiation of field mapping and sampling were made. Numerous historic silver producers are known within the patented claim block. Limited modern work has indicated the potential for a bulk minable target or underground higher grade targets.

The Treasure Hill property is subject to a 3% NSR, 2% of which can be purchased before March, 2010 and 12% of which can be purchased for escalating amounts from USD $500,000 to USD $ 3,000,000 until April 2012. In addition, 170 unpatented claims included in the property are leased by Golden Predator and subject to an additional sliding scale royalty between 2% and 5%. Golden Predator has the right to purchase these claims for USD $2,000,000.

Taylor Mill Facility

Golden Predator will also be granting to Silver Predator a ten year right to earn up to a 50% interest in the Taylor Mill, a 1,200 tonne (1,320 ton) per day flotation mill located on the Taylor Project. Silver Predator will earn its interest by incurring rehabilitation expenses equal to the appraised value of the Taylor Mill at the time a rehabilitation and operating plan is presented by Silver Predator and approved by Golden Predator.

Strategic Metals Properties

The eleven properties to be contributed by Strategic Metals are the Blue Heaven, Quarterback, Touchdown, Pigskin, Ranch, Shar, Uno, Jake, MC, Evoy and Rogue. All are located in southern Yukon Territory and northern British Columbia, and all are 100% owned with no underlying royalties. These properties total 389 mineral claims and 12 mineral tenures that collectively cover 29,406 acres (11,900 hectares). Each project hosts silver-lead-zinc vein and/or carbonate replacement-style mineralization. Wide-spaced drilling and excavator trenching have produced numerous promising results. These properties also host highly prospective soil geochemical and geophysical anomalies that have not yet been drilled or trenched.

Blue Heaven Project

The Blue Heaven project is located 110 km west of Watson Lake and is accessible via a 40 km gravel road from the Alaska Highway. It has been explored intermittently since the early 1970's and was most recently explored in 2007. Mineralization includes: silver-rich galena veins that are found within granitic plutons and adjacent sediments; zinc-lead-silver in carbonate replacement zones within a thick section of calcareous sediments; and tungsten-copper disseminations in skarnified horizons. Silver potential is demonstrated by a 51.47 dry tonne bulk sample of hand sorted material, which was smelted in 1999. That bulk sample graded 8563 gpt silver, 56.2% lead and 9.5% zinc. Relatively little work has been done to test carbonate replacement or skarn mineralization but initial results are encouraging. Chip samples from an excavator trench across one of the carbonate replacement zones averaged 5.0% lead, 3.6% zinc and 65.5 gpt silver over a length of 35.8 m. A chip sample from a trench at a skarn zone graded 0.3% WO3 and 0.31% copper over 3.5 m.

Quarterback Project

The Quarterback project lies 110 km west of Watson Lake and about 14 km northeast of the Blue Heaven property. Access is normally by helicopter but a bulldozer trail extends from the property to the Alaska Highway. Exploration has been done intermittently from the mid-1970's to 2007. Mineralized bedrock and glacial boulders are found in a number of zones over a 6 km strike length. The most prospective area is marked by an extensive field of glacially dispersed galena-sphalerite-pyrrhotite-pyrite rich boulders. Ten samples from different boulders returned an average grade of 9.98% zinc, 9.10% lead, 0.13% copper and 143.9 gpt silver. This mineralization exhibits textural features that suggest it is carbonate replacement style. Mechanized trenching encountered deep overburden and was unable to discover a bedrock source. Diamond drilling intersected vein style mineralization which included an intercept that assayed 13.50% zinc, 8.43 % lead and 107.5 gpt silver over 1.75 m. VTEM surveys flown in 2007 detected conductors and magnetic highs in an area located up-ice from the mineralized boulders, which has not been tested by drilling. Both weak and strong VTEM anomalies were also identified down dip from silver-lead-zinc-copper bearing, jasperoid altered horizons located five km to the west. Hand trenches in that area averaged 142 gpt silver, 4.9% lead, 0.3% zinc and 0.13% copper over 5.2 m. Only two diamond drill holes have explored this area with the best intercept grading 125 gpt silver, 1.70% lead, 2.55% zinc and 0.45% copper over 2.18 m.

Rockhaven Properties

The five properties to be contributed by Rockhaven are the Plata, Groundhog, Zap, Grayling and Cyr. All are located in the Yukon Territory and are 100% owned with no underlying royalties. These properties total 505 mineral claims that collectively cover 25,130 acres (10,170 hectares). Each hosts silver-lead mineralization and/or soil geochemical anomalies.

Plata Project

The Plata project consists of 281 contiguous mineral claims that cover 14,233 acres (5,760 hectares). A total of 35 silver+lead±gold-bearing vein and bulk tonnage zones have been discovered to date and many prospective geochemical and geophysical anomalies are undrilled. Previous operators produced 290,000 ounces of silver from ore mined from shallow open cuts on the property. Numerous similarities exist between the silver-lead veins discovered at Plata and those found in the Keno Hill Silver Camp, Canada's second largest historical primary silver producer, which is located 140 km to the west.

Diamond drilling by Rockhaven has primarily focused on exploring a vein developed in the plane of the Plata Thrust Fault. This vein has been traced about 500 m down dip and 850 m along strike. Highlights from the drilling include 769 gpt silver, 3.6 gpt gold, 2.44% lead and 3.0% zinc over 1.3 m and 711 gpt silver, 4.57 gpt gold, 7.24% lead and 6.17% zinc over 1.52 m.

Excavator trenching was conducted in 2009 by Rockhaven at the P-2 vein which consists of massive, poddy and disseminated galena, tetrahedrite, and sphalerite hosted in siderite gangue. Chip samples from closely spaced trenches returned a weighted average of 812 gpt silver, 24.48% lead and 17.02% zinc across an average width of 1.93 m and along a strike length of 85 m. The vein remains open to extension along strike in both directions.

Excavator trenching in 2009 also discovered a new type of mineralization at the Etzel zone. This mineralization has bulk tonnage potential and consists of clay and scorodite altered quartz-filled fractures that host disseminated galena, tetrahedrite and sphalerite. The longest trench in the zone graded 94 gpt silver, 0.51% lead, 0.29% zinc and 0.20 gpt gold over 40.54 m. The other trenches returned a weighted average of 260 gpt silver, 1.60% lead, 0.09% zinc and 0.15 gpt gold across 19.70 m. This discovery is open to extension in all directions and will likely be the focus of future diamond drilling.

Other Projects

The Groundhog, Cyr and Grayling properties consist of 174 mineral claims that cover a 33.8 km² area. Mineralization discovered to date consists of silver-lead veins, replacement-style zinc and gold-bearing oxide showings.

The Zap property is located 16 km northeast of the recent Rau Gold discovery of ATAC Resources Ltd. It consists of 50 mineral claims that cover a 10.3 km² area. The Zap property hosts silver-lead-zinc vein and breccia mineralization.
