Sonora Gold Options Greta Property and Receives Initial San Enrique Results from Teck Cominco

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Feb. 2, 2006) - Sonora Gold Corp. (TSX VENTURE:SGG)(PINK SHEETS:SGGFF) announces that it has entered into an agreement (the "Agreement") with Minera Teck Cominco S.A. de C.V. ("TCM") whereby TCM has optioned the Greta property in the State of Sonora, Mexico. TCM is a wholly-owned subsidiary of Teck Cominco Limited. This Agreement amends an August 31, 2005 option agreement whereby Sonora granted to TCM an option on their San Enrique property some seven kilometres southwest of the Greta property. Claim staking by TCM within the Area of Mutual Interest has resulted in a current land position of 8,492 hectares that is subject to the TCM option as compared to the original 1,858 hectares. Sonora retains a 100% position in 3,700 hectares to the north of the Greta and San Enrique properties (the Santa Gertrudis Claims).

Under the terms of the Agreement, TCM can now earn a 60% interest in both the Greta and San Enrique claims by spending US$3,500,000 on exploration on or before August 31, 2010 with the option to earn a further 10% for additional expenditures of US$3,500,000. In addition TCM is to pay Sonora Gold US$80,000 on closing of the Agreement, US$50,000 on August 31, 2006, plus an additional payment of US$50,000 on August 31, 2007. Additionally, if the Greta property is put into production, Sonora will receive a bonus payment of US$450,000.

The Greta property comprises 954 hectares and lies nine kilometres southeast of the main past-producing gold properties at Santa Gertrudis. Several near-surface bulk tonnage gold occurrences were drilled off by previous operators on the Greta property including the La Gloria, Greta, Ontario, Tracy and El Tigre. The Greta property is also considered to have excellent potential for hosting deeper, high-grade Carlin-style mineralization due to the spatial coincidence of several favourable geological, structural, geochemical and geophysical criteria, including:

- Proximal intrusive bodies, as indicated by the presence of aeromagnetic anomalies with coincident, regionally developed aureoles of quartz-pyrite hornfels, marble and skarn;

- Substantial thicknesses (greater than 300 meters) of favourable stratigraphy;

- Clearly-defined, high-angle feeder structures that intersect the favourable stratigraphic units near the intrusive bodies;

- The presence of sedimentary rock-hosted, disseminated gold occurrences at the margins of the hornfels aureoles;

- Strongly anomalous gold, arsenic, mercury, silver and copper indicated by soil geochemistry.

SAN ENRIQUE PROGRESS REPORT

TCM has conducted geological mapping, rock and soil geochemistry and limited reverse circulation drilling on the San Enrique copper-molybdenum property. The initial drill plan was for five holes totalling 2,000 meters in order to obtain lithological and structural information as well as test geophysical anomalies. Due to a late start and equipment difficulties only four holes totalling 1,198 meters were completed prior to the year-end break.

All of the four holes drilled to date intersected wide zones of highly anomalous molybdenum, copper and zinc with occasional high precious metal values. The mineralization is concentrated in veins, veinlets and stockworks in hornfels and diorite. Drill holes RCSE #2 and RCSE #3 were mineralized over their entire lengths (456 ppm Cu, 157 ppm Mo over 292.6 meters and 460 ppm Cu, 214 ppm Mo over 207.3 meters respectively). Hole RCSE #1 returned 202.7 meters grading 430 ppm Cu and 150 ppm Mo. Significant gold mineralization (up to 1.57 grams per tonne) was occasionally associated with the higher grade copper-molybdenum values. The first four holes of TCM's drill program did not test all of the copper-molybdenum soil geochemical anomalies and several remaining large target areas will be the focus of the next phase of drilling. Previous drilling by Sonora Gold in this area returned values up to 27.6 meters grading 0.148% Mo, 0.308% Cu and 6.7 grams per tonne Ag.

Drilling is scheduled to resume in late February 2006 with approximately 1,600 meters of drilling in four holes. Additional analysis and field work will continue to determine additional drilling locations.
