Zacatecas J/V with Yale looking good !!
--------------------------------------------------------------------------------
Yale Resources Ltd. (TSX-V - YLL and Frankfurt - YAB) is pleased to report that results from the first phase sampling and mapping program on the Salvador, Zacatecas and San Jose properties confirms the significant potential of the properties. These three properties, along with the San Sabino claim, make up the Zacatecas Venture, in which Yale has the right to earn an 80 % interest in from IMPACT Silver Corp. (IPT-V). The Zacatecas district is one of the most famous historic silver mining districts in Mexico.
The historic mines throughout each of the properties and samples near these mines grading up to 145 ounces per tonne silver (see news release dated October 17, 2006) combined with the recent results show that there remain significant exploration potential within the properties and that each property warrants drill testing. A drill is being mobilized to the Zacatecas area and will arrive towards the end of February to commence a core drilling program on these properties.
This ongoing work is being supervised by consulting geologist Edward Lyons, P.Geo.
Salvador and Zacatecas -- 1,337 g/t silver found in outcrop.
The Salvador and Zacatecas properties are contiguous and host two main veins (with splays) that have silver grades that range from 100 to 1,410 g/t. The Salvador Vein lies to the NE and has been traced for 450 metres within the property. The Zacatecas Vein has one sub-parallel vein and has little outcrop but many shafts and dumps that indicate a strike length of at least 350 metres within the property.
Of the 61 samples analyzed, 31 contained over 100 g/t silver. Due to the lack of outcrop (primarily a result of mining activity) a majority of sampling was done on the historic mine dumps that exist throughout the properties. This recent sampling of these dumps confirmed the earlier sampling and returned average grades 200 to 300 g/t silver.
The highlight of the sampling program was one pair of chip samples that averaged 1,337 g/t silver over 1.08 metres true vein width on the SE part of the Salvador Vein. This confirms that higher grade silver mineralization does exist within the vein system and that the down dip continuation of the veins is a viable exploration target.
San Jose -- additional silver and gold exploration target identified.
The San José concession hosts two vein systems. The northern San José vein is made up of two sub-parallel veins with an oblique splay. Several shafts and cuts on the vein mark its length over 250 metres but the strike length is open in both directions. The sub-parallel vein along the south fault contact has little development and is poorly exposed but extends into a zone of silicification.
Of the 44 samples analyzed, 14 contained over 93 g/t silver. A significant difference at San Jose from the other claims is the consistently elevated gold values. Previous sampling of dumps (see news release dated October 17, 2006) identified gold values up to 7 g/t and silver values up to 145 ounces per ton. Recent sampling returned 2,180.0 g/t silver (or 63.5 ounces per ton) and 3.15 g/t gold. Outcropping vein at this dump site returned 208.0 g/t silver, 1.00 g/t gold, and 2.32 % lead over 57 cm.
The eastern extension of the San Jose vein is poorly exposed but one outcrop graded 428.0 g/t silver and 0.97 g/t gold over a true width of 0.98 metres.
A new exploration target has been identified within the San Jose claims as recent sampling one hundred and fifty metres away from the known workings and dumps returned gold values from 0.27 to 0.87 g/t and silver values up to 531.0 g/t (15.4 oz/T) in outcrops over a widespread area. Listed below is a list of results from this new area:
Concession Type True width (m) Ag g/T Au ppm Pb %
San Jose float 176.0 1.12 -
San Jose chip 0.99 149.0 0.27 1.75
San Jose chip 0.98 218.0 0.36 1.16
San Jose chip 0.98 531.0 0.87 -
Field work is on going with additional samples having been sent to the lab. Results will be released when received and interpreted.
