The Realito Trend consists of a northeasterly trending zone measuring approximately 2,000 metres in length and 100 to 200 metres in width. The strike extensions of the trend have not been fully defined at present. Seven areas of gold mineralization have been found along this trend to date. From the northeast to the southwest, they are known as Chalate, Centenario, Mina Loca, Promontorio, Golfo de Oro, Central, Brasiles, and El Tigre. Of these eight areas, the Golfo de Oro, Central, and Centenario prospects have had sufficient drilling density to enable an estimate of the tonnage and average grade of the gold mineralization present.
Gold mineralization in the Realito Trend occurs in a number of flat lying to gently dipping zones or lenses, and the diamond drilling of the past and modeling activities focused on three of these: the Golfo de Oro, Central, and Centenario targets. These mineralized zones occur at a depth ranging from surface to a maximum of approximately 250 metres from the surface. Both open pit and underground mining methods are envisioned for these zones.
A program of diamond drilling was carried out by Red Tiger Mining's predecessor company at the Realito Trend from January 13, 2004 to June 3, 2004, during which a total of 36 drill holes totalling 5,108.45 metres were completed., complementing the large amount of historic reverse circulation and diamond (cored) drilling. The main purpose of the drilling program was to provide additional information as to the distribution and grade of the gold mineralization found at the Golfo de Oro, Central and Centenario prospects. A small number of drill holes were completed on other targets elsewhere on the property which were believed to hold potential of hosting significant gold mineralization.
Realito Gold Resources
Distinct, separate and individual gold bearing areas, some of which have been hand mined by artisans as long as 200 years ago occur on the property. The Independent Technical Report for Resource and Reserve Disclosure for the San Antonio Properties, Sonora State, Mexico (by P&E Mining Consultants Inc.), filed on August 12, 2013, concluded an update resource estimation on the Sapuchi Gold Target and the Realito Gold Target:
The Realito Trend is located 1,500 metres to the south-west of LdC. It consists of a north-easterly trending zone measuring approximately 2,000 metres in length and 100 to 200 metres in width. Eight areas of open ended gold mineralization have been found along this trend to date. From the north-east to the south-west, they are known as Chalate, Centenario, Mina Loca, Promontorio, California, Golfo de Oro, Brasiles, and El Tigre. Of these eight areas, the Centenario, California and Golfo de Oro prospects have had sufficient drilling density to enable an estimate of the tonnage and average grade of the gold mineralization present. This is summarized in the following table:
|Realito Gold Underground Resource @ 2.5 g/t Au Cut-Off Grade|
|Classification||Tonnes||Au (g/t)||Au (oz)|
|Golfo de Oro|
|Measured & Indicated||1,200,000||4.67||180,300|
|Measured & Indicated||295,000||3.79||35,900|
|Measured & Indicated||244,000||3.59||28,200|
|Measured & Indicated||1,739,000||4.37||244,400|
|Realito Gold Open Pit Resource @ 1.0 g/t Au Cut-Off Grade|
|Golfo de Oro|
|Measured & Indicated||181,000||2.38||13,800|
|Measured & Indicated||370,000||1.93||22,900|
|Measured & Indicated||551,000||2.08||36,700|
The cut-off grades used are: Open Pit Gold Cut--Off Grade (Mill Incremental Grade) at 85% process recovery = 1.00 g/tAu; Underground Gold Cut-Off at 85% recovery = 2.5 g/tAu, at an applied gold price of US$1,550 per ounce.
