$B!&(B         XTIERRA INTERSECTS 11.5 g/t GOLD OVER 4 METRES AT EL DORADO

$B!&(B         EXERCISES OPTION TO ACQUIRE EL DORADO PROJECT

Toronto, April 15, 2010, Xtierra Inc. (TSXV ? XAG) ($B!H(BXtierra$B!I(B or the $B!H(BCompany$B!I(B), reports that it has completed a preliminary diamond drilling programme at El Dorado which has resulted in the identification of several new vein structures, the intersection of significant gold and silver mineralization and the Company has exercised an option to acquire the El Dorado gold project located in the historic Pinos gold district within the Central Mexican Mineral Belt in southeastern Zacatecas.

Drill Results

Xtierra has completed a preliminary diamond drilling programme at El Dorado as part of its initial due diligence evaluation. Five inclined holes were drilled at angles between -35 and -45 degrees for a total of 1,384.55 metres, of which two holes were collared underground in the main El Dorado adit.

The number of mineralized veins identified on the property has been increased to twelve with a combined strike length in excess of 1,300m. The veins have a north-south orientation and trend parallel or sub-parallel with the main El Dorado gold-bearing structure. The veins are emplaced within a quartz-stockwork at the southern margin of a rhyolitic intrusive host. The drilling was carried out over a surface area of 600 m by 200 m along the stockwork contact and to a maximum vertical depth of about 200 m.

Some of the widths on the veins are significantly greater than had been anticipated with a zone of 7.80 m occurring in hole ED-1 averaging 4.72g/t gold on the Gavilan vein and a 4.00 m intersection averaging 11.55g/t gold on the newly found El Oro vein (hole ED-5). In addition, excavation of the drill pad in the underground adit on the El Dorado vein has demonstrated that the mineralized zone extends well into the hangingwall as evidenced by the discovery of an additional high grade vein containing 189.0 g/t gold within a 6.0 m wide zone of mineralization (previously reported March 4, 2010).

Of the two remaining, surface drill-holes, ED-4 was a stratigraphic hole in a separate area and was not expected to intersect auriferous vein structures. However, minor veinlets of anomalous gold in the 0.1-0.3 g/t gold range were encountered. This hole also intersected two zones of highly anomalous mercury content. The zones occurred in brecciated, carbonaceous limestone near the contact with tuffs. One zone of 35.0 m between 250.0 m and 285.0 m averaged 9.90g/t mercury and a zone of 6.0 m between 227.0 m and 233.0 m averaged 14.27 g/t mercury. Analytical results for drill-hole ED-6 are awaited.

The El Dorado project is at an early exploration phase and further work will have to be undertaken in order to ascertain the full potential of the prospect which has potential for high grade epithermal gold and silver veins as well as lower grade stockwork mineralization.

Commenting on the results of the initial exploration/drilling phase, Mr. Terence McKillen CEO of Xtierra Inc. said, $B!H(BThe results obtained from Xtierra$B!G(Bs preliminary due diligence work, including the results of the first few drill holes is very encouraging. The drilling demonstrates the presence of many additional vein systems parallel and sub-parallel to the original high grade El Dorado vein which is currently developed on a single adit level. Results indicate that the veins can vary from a few centimeters to almost 8 metres in width. The highly anomalous mercury levels detected over a width of 35 metres in hole ED-4 are very intriguing and may reflect mineralization at deeper levels.$B!I(B Mr. McKillen added, $B!H(BXtierra will allocate a significant budget to additional exploration work at El Dorado through the balance of 2010.$B!I(B

Analytical results are now available for the first four drill-holes. The main intersections of these are listed in the tables below.

Samples were prepared at the Stewart Group laboratory in Zacatecas and fire assayed with AA finish ? (Au) and ICP ? (multi-element) by Stewart Group in Kamloops, British Columbia.  Standards and blanks were used regularly for quality control.

Exercise of Option

Golden Dust S.A. de C.V., ($B!H(BGolden Dust$B!I(B) an indirect, wholly$B!>(Bowned subsidiary of Xtierra will acquire the interest in the El Dorado property by staged payments (all US Dollar amounts). Two payments totaling $42,558 have previously been made. With the election to purchase the property, Golden Dust has made a further payment of $83,023. The full purchase price will be satisfied by three additional equal payments of $268,217 due respectively on January 15 of 2014, 2015 and 2016, for a total consideration of $1 million. If Golden Dust completes a feasibility study and such study indicates a mineral reserve estimate containing between 250,001 and 500,000 ounces of gold, a bonus to the purchase price of $500,000 will be paid, or if such mineral reserve estimate is greater than 500,000 ounces of gold, a bonus purchase price of $1 million will be paid on the same staged basis as the three interim payments. The maximum purchase price to be paid is $2 million.
