San Gold Corporation - one of Canada's most exciting new exploration companies and gold producers.
Andy,
I noticed the same thing, except the name.
I was wondering how they could show so many oz in the indicated and SGR could only show ozs in the inferred and all that with 350,000m drilled.
What a clown............................PS" This so called in-house 43-101 was prepared by dale, a qualified person under a 43-101 so the numbers are his..Please refer :
MINERAL RESOURCE AND RESERVE ESTIMATE
Historically, resources at the Rice Lake Project were estimated using the polygonal method. More recently, with the use of AmineĀ® software, the measured and indicated mineral resource estimate is derived by creating a block model.
The construction of the block model begins by creating 3D wireframes or meshes around mineralization as determined from both underground and surface drilling, underground mapping and sampling, and/or surface mapping and sampling. Once constructed, the drill hole and chip assays enveloped in the meshes are composited by the software and used to interpolate grade blocks. The resource block model was estimated utilizing inverse distance squared methodology on a block size of 3 feet x 3 feet x 3 feet.
The mineral resources at the Rice Lake Project are classified as measured, indicated, and inferred categories based on the following criteria:
1) Measured Mineral Resource:
A resource block can be classified as measured if its vertical and lateral extents are bounded by mine development including sills, lifts, and benches that has been sampled; or the block has been projected to a maximum of one mine level (approximately 50 feet) from mine development and there are diamond drill hole intersections to indicate the continuity of the structure below or above the development.
2) Indicated Mineral Resource:
A resource block can be classified as indicated if it has been projected to a maximum of one mine level (50 feet) from development if there is no drilling beyond to indicate its continuity, or the block has been sampled by tightly spaced diamond drill holes on structures that have either been previously mined or mapped and sampled at surface. A closely spaced diamond drill program is generally less than 100 feet between drill hole intersections.
3) Inferred Mineral Resource:
Inferred mineral resources are determined using the polygonal method from widely spaced diamond drill holes (greater than 100 feet between intersections) whose structure can be extrapolated from previous production history and relevant geologic data.
The Company's mineral reserve estimate is developed by incorporating measured and indicated mineral resources on which detailed near-term mine planning has been applied to date for the Rice Lake Project. Each mining area has been analyzed and a distinct extraction ratio and dilution factor was calculated using a minimum mining width of 2.7 metres with a mill recovery of 93%. Mineral resources which can be shown to be economically extracted at a gold price of US$1,260 per ounce are assigned to proven and probable mineral reserve status based on geological confidence and professional opinion within the near-term mining plan. As the mid-term to long-term mining plan is developed, further measured and indicated mineral resources are anticipated to convert to mineral reserves
