The property is located approximately 140 km north of the state capital city of Durango, Mexico with good local access and infrastructure.
The project was acquired for its potential to contain low sulfidation bulk tonnage gold deposits - focus to date has been on the La India Breccia.
Northair's exploration work includes 96 samples have been taken from the main breccia zone averaging 0.844 g/t gold with a high of 10.80 g/t gold.
In 2008 a joint venture agreement was signed with Fresnillo PLC ("Fresnillo"), a subsidiary of Industrias Peņoles, S.A. de C.V. ("Peņoles").
Fresnillo's exploration work includes surface geological mapping, sampling (including 158 rock chip samples within the main breccia zone reporting an average grade of 0.63 g/t gold) and a drill program consisting of 8 diamond drill holes totaling 867 metres.
In 2009, Fresnillo returned the property to Northair
Joint venture partner being sought
The La India Project is located in the Sierra San Francisco, approximately 30 kilometres east of the small city of Santiago Papasquiaro, and approximately 140 kilometres north of the capital city of Durango. The La India Project has excellent access and infrastructure.
La India was identified as an attractive acquisition target by exploration staff in June 2006, as part of the Company's generative exploration program. Initial sampling on the project by Northair reported encouraging gold mineralization within an intrusive breccia, leading to land acquisition. Regional reconnaissance indicates that the exploration potential distal to the known mineralization is excellent. Two small gambusino workings have been found within the project area, but there is no evidence that the property has been examined by other modern exploration companies. Northair initially acquired concessions covering approximately 1800 hectares through staking and the option to purchase a 300 hectare privately held concession. In 2009, joint venture partner, Fresnillo completed significant technical work as well as 867 meters of drilling in eight holes. Drilling encountered anomalous intervals of gold mineralization in all eight holes; however no mineralized intervals of potentially economic grades were reported and Fresnillo returned the property to the Company. Northair has elected to terminate its option to purchase the privately held concession, however it will retain concessions covering approximately 1600 hectares that were originally acquired through staking and will seek a joint venture partner.
During its initial field evaluation in June 2006, the Company took a total of 16 reconnaissance samples. The average value of these samples was 1.486 g/t gold, with a high of 10.8 g/t and a low value of 0.02 g/t. Samples consisted of panel grabs as well as continuous chips taken over intervals ranging from 2 to 10 metres. During the months of August and September, the Company conducted regional and detailed mapping and sampling, and stream sediment sampling. Assay results were received from 43 additional samples taken within the main zone. Included within the samples were two lines of continuous sampling over limited outcrop. These samples were primarily five metre continuous chips. Line one reported 32 metres @ 2.31 g/t gold and line two reported 48 metres @ 1.08 g/t gold, essentially perpendicular to each other.
37 additional samples were taken which include 2.42 g/t gold over a 15 metre interval, with the remainder of the samples mainly 5 metre chips taken from outcrops within the mineralized system. Of the 37 samples taken, 15 returned values exceeding 0.5 g/t gold, and four reported 2.10, 2.61, 2.55 and 2.11 g/t gold over 5 metres. Geological mapping was concentrated within the currently defined zone of mineralization and alteration, which was mapped over a strike length of approximately 300 metres with widths locally exceeding 70 metres.
Fresnillo commenced exploration in mid 2008 and in a January 2009 report provided to Northair, offered details of its initial exploration program on the property. The program included geological mapping and over 2,000 rock chip samples within the project area. Fresnillo's geological mapping has increased the size of the breccia and has defined an irregular surface area of mineralization having an exposed strike length of approximately 400 metres with widths ranging up to 60 metres. From the maps provided by Fresnillo, Northair calculates that Fresnillo has taken 158 rock chip samples within the main breccia zone reporting an average grade of 0.63 g/t gold.
In 2009, Fresnillo completed a first phase diamond drill program, which consisted of eight holes, totaling 867 metres in length. The Fresnillo program tested two mineralized zones, the South Breccia previously outlined on surface by Northair and the North Breccia discovered by Fresnillo and located approximately 500 metres north of the South Breccia. Fresnillo's drilling encountered anomalous intervals of gold mineralization in all eight holes; however no mineralized intervals of potentially economic grades were reported.
La India is an iron oxide low sulfidation gold system with significant tonnage potential. Mineralization occurs in an intrusive rhyolite breccia with exposed widths ranging from 25 to 70 metres and a strike length of at least 200 metres. The mineralized breccia zone contains hydrothermal and explosive fragments of rhyolite porphyry, cemented by a matrix of siliceous iron oxide. High density (<1 cm wide) stockworking quartz veinlets cut both the matrix and fragments of the breccia, which intrudes rhyolite volcanics. The area is also cut by several large regional extensional faults. The higher elevations within the property are covered by post-mineral welded ash and ignimbrite. All units are tentatively identified as belonging to the Superior Super Group. Mineralization is postulated to be genetically associated with rhyolite porphyries.
