Location
La Cigarra Project is located outside the municipality of Parral, in the State of Chihuahua along the eastern fringes of the Sierra Madre Occidental in north central Mexico. La Cigarra consists of 6 privately held concessions, totaling approximately 335 hectares and has good road access, topography and infrastructure.
Overview
La Cigarra was identified as an acquisition target by exploration staff late in 2008, as part of the Company's generative exploration program. Reconnaissance and initial sampling results completed by Northair confirm numerous silver occurrences currently traced over a 3 kilometre trend of mineralization. The Company, through an ongoing technical review has defined three potentially significant zones of silver mineralization within the property and believes that all three zones have the potential to contain both high grade vein as well as bulk tonnage surface minable silver deposits. Although there are dozens of small to medium sized old historic workings within the project area, there is no evidence of any modern exploration. The Company's wholly-owned subsidiary, Grupo Northair de Mexico, S.A. de C.V. can acquire a 100% interest in the optioned concessions by paying US$450,000 over a five year period.
Work Performed
Exploration at La Cigarra is targeted on three main zones:
The Las Carolinas Zone is located in the southern portion of the property. Mineralization has been traced over a strike length of approximately 500 metres, and is open in both directions. 35 samples taken by the Company reported an average grade of 192.3 g/t silver including a low of 4.3 g/t silver over 10 metres and a high of 334 g/t silver over 4 metres.
The San Gregorio Zone, which is 800 metres to the north of Las Carolinas. The zone contains two distinct areas referred to as East Hill and West Hill. East Hill contains mineralization exposed through limited outcrops and mine workings over a northwesterly trending zone of approximately 185 by 50 metres, dipping moderately to the northeast. 32 samples taken by the Company reported an average grade of 180 g/t silver including a low of 10 g/t silver over a length of 4 metres and a high of 991 g/t silver over a length of 3 metres.
West Hill, located parallel to the structural fabric of the East Hill area and 80 metres to the southwest, contains a northwesterly striking, moderately northeasterly dipping vein system. The main vein is open in both directions and has been traced on surface over a strike length of approximately 340 metres with exposed widths of mineralization that range up to 15 metres. The Company has taken 28 samples which reported an average grade of 187.3 g/t silver, including a low of 12.9 g/t silver over a length of 3 metres and a high of 660 g/t silver over a length of 2 metres.
The La Boracha Zone sits approximately one kilometre north of San Gregorio, and contains numerous old prospect pits and small workings. In the centre of the zone, the Company has sampled vein and stockwork mineralization that occurs within an area measuring approximately 450 metres in length by 50 to 75 metres in width. 51 samples taken by Northair reported an average grade of 82 g/t silver, including a low of 7 g/t silver over 4.5 metres and a high of 348 g/t silver over 3 metres.
2010 Drill Program
In the summer of 2010, the Company carried out a phase I drill program (the first known drilling on the property) to confirm surface silver values and expand geological knowledge on the property. Drilling intercepted significant widths of altered and mineralized sediments and volcanics with highlights of near surface drill intercepts of 32 metres of 132.4 g/t silver in Hole CRC-10-06 at the San Gregorio Zone, 10.7 metres of 172.5 g/t silver in Hole CRC-10-01 at the Las Carolinas Zone and a near surface intercept of 7.26 metres of 68 g/t silver in Hole CRC-10-13 at the La Boracha Zone. In addition to silver, all intercepts returned anomalous and locally significant zinc with lead and copper.

Gold Analysis
During the phase I drill program, which was focused on potential silver mineralization, the Company carried out a random analysis for gold on selected drill intercepts. This analysis returned highly anomalous gold values and to further investigate the significant selected gold assays, Northair chose Hole CRC-10-11 to be completely analyzed for gold. Results of this analysis are encouraging as the entire intercept, over 100 metres in length, confirmed anomalous gold mineralization highlighted by 1.5 metres of 1.18 g/t gold within a near surface intercept of 10.7 metes of 0.41 g/t gold or 15.3 metres of 0.36 g/t gold.
As a result of the positive gold assays from Hole CRC-10-11, the Company is currently reviewing the complete drill data base and will begin assaying additional drill holes for gold. Holes to be assayed for gold will be selected based on multi-elemental analysis, as studies reveal that gold mineralization within the reported drill intercept correlates strongly with silver, lead and antimony. This is consistent with the element correlation with silver from surface samples for both the San Gregorio and La Boracha zones. Based on the statistical correlation alone, both zones could very likely be as anomalous in gold as they are in silver. Results of the additional gold assays will be announced as soon as they become available.
Geology
La Cigarra is located within the low lying hills of the Sierra de Hoyas, which lies along the eastern flanks of the Sierra Madre Occidental province. Within the project area, post-mineral Oligocene rhyolite volcanics belonging to the "Upper Volcanic Complex" overlie Cretaceous age sediments. The sediments are generally non-calcareous, and include shale, siltstone and sandstone. Sedimentary rocks are locally intruded by rhyolite dikes, sills and small stocks, and range in texture from aphanitic to porphyritic. Intrusive rocks are more common along the areas of higher topography of the Sierra de Hoyas, and are frequently highly silicified. There is a significant structural deformation within the project area. Stratigraphy generally dips moderately from northwest to northeast. Preliminary mapping indicates there may be a general anticlinal feature paralleling the Sierra. There are numerous regional deep seated northwest extensional fault systems within the project, which coincide with the regional Parral mineral belt. These faults are associated with controlling intrusive emplacement and mineralization. A secondary northeast set of faulting is also apparent.
Work Planned
Northair The Company is currently developing plans for the next stage of exploration to commence in the fall of 2010. It is anticipated that the program will include further drilling and field work to expand targets on the property.
