Yale Continues to Encounter High Grage Silver at Los Amoles

News Release #12-03

Yale Resources Ltd. (TSX-V - YLL and Frankfurt - YAB) is pleased to report that sampling at the Los Amoles Silver Property, located in central Sonora, continues to show the potential for multiple sampling techniques within the property as a test sampling of select shafts has returned the widest and highest grade results to date from the property. Work at Los Amoles is being performed by Yale on behalf of Sonora Resources, who by funding the exploration have the right to earn a 70% interest in the property.

The central target area of the property, which surrounds the historic Rosales mine, measures approximately 300 by 600 metres and has the highest concentration of historic workings with greater than 20 shafts and adits identified to date. The distribution of workings on different veins and different sections of each vein provides access to various levels of the mineralizing system due to the topography. All mineralization encountered to date is open along strike and to depth. The recently completed work program was designed to test the exposed vein in the walls of the vertical shafts of select workings. This has proven very effective in getting a true sense of the mineralization that is not exposed at surface. Below are the highlights of the sampling program:

Sample description	Width (m)	Ag (g/t)	Au (g/t)	Ag Eq¹ (g/t)

Rebaje shaft at 1.1 m	1.39	241.85	0.38	264.41
Rebaje shaft at 1.3 m	1.05	278.35	0.80	326.64
Rebaje shaft at 4.5 m	1.54	144.66	0.34	164.99
Rebaje tunnel	1.00	308.70	1.32	387.60
Rebaje tunnel	0.70	1,131.49	1.60	1,227.24

1. Silver equivalent calculations use metal prices of Au US$1,200/oz and Ag US$20/oz.
Metallurgical recoveries and net smelter returns are assumed to be 100%.

In addition, a test soil grid covering an area measuring 200 by 400 metres proved very effective as it defined a 250 metre curvi-linear silver anomaly that has been interpreted to represent the buried continuation of a vein as well as several discrete anomalies that occur immediately down slope from historic workings and their respective waste piles.

As a result of the continued favourable results a much larger comprehensive sampling program is being proposed to Sonora Resources for the next exploration campaign on the project such that targets can be prioritized for drilling.

The work at Los Amoles during the past year has advanced the project significantly by concentrating on a two by three kilometre mineralized zone defined by a strong colour anomaly and now known to contain at least 60 veins with strike lengths up to 1 kilometre, 40 historic workings (adits and excavations) and 19 shafts.

About the Los Amoles Property:

The early stage wholly owned 16.3 square kilometre Los Amoles Property is located approximately 150 kilometres northeast of the Hermosillo, Sonora State, Mexico. The property is approximately 10 kilometres northeast of the La Caridad Mine, operated by Grupo Mexico, which is one of the largest mining and processing complexes in Mexico.

Sonora Resources Ltd. has an option to earn a 70% interest in the property by paying to Yale US $ 50,000 (received), spending US $ 900,000 ($200,000 spent) on exploration expenditures and issuing 1,000,000 shares (600,000 have been received) to Yale over three years.

Work performed to date by Yale has concentrated on an area (the Rosales area) that is on the south eastern edge of a 4.0 by 2.75 km regional magnetic anomaly. Yale's interpretation is that the Rosales area represents silver-lead +/- gold veins that are distal to a porphyry system. The potential for this regional anomaly to reflect a buried porphyry has yet to be tested. Many of Sonora's most significant porphyry deposits are located within 70 km of the Los Amoles property.

Samples from Los Amoles were prepared and analyzed by IPL Inspectorate in their facilities in Mexico and Vancouver, respectively. Samples generally consisted of 1-3 kg of material. Gold and silver analyses were performed by 30 gram fire assay with an AA finish. Samples with greater than 100 g/t silver were re-assayed using gravimetric methods.

Ian Foreman, P.Geo., is Yale Resources' Qualified Person, as defined by National Instrument 43-101. The Los Amoles property is an early stage project that requires additional sampling and geological mapping to fully determine the project's potential.

On behalf of the Board,

"Ian Foreman"

President
