Makamint,
great questions and i will try to give you an answer that is in my thoughts.

Measured, indicated and inferred really depends on if an independent study verified the deposit as economic, marginally economic or sub-economic. In OVR's circumstance, they have already done the calcs and confirmed it to be economic.

Therefore their identified resources are classified into demonstrated reserves [i.e. measured and indicated] and inferred reserves. Mineral reserves are construed to be valuable and legally and economically and technically feasible to extract. In OVR's situation, they are NOT mineral occurrences but rather mineral resources. As such,

Indicated resources - are simply economic mineral occurrences that have been sampled (from locations such as outcrops, trenches, pits and drillholes) to a point where an estimate has been made and at a reasonable level of confidence.

Measured resources are indicated resources that have undergone enough further sampling that a 'competent person' (usually a geologist) has declared them to be an acceptable estimate and at a high degree of confidence.

Lastly, Mineral reserves are resources known to be economically feasible for extraction. Reserves are either Probable Reserves or Proven Reserves. Generally the conversion of resources into reserves requires the application of various modifying factors including;

- metallurgy [OVR is in the midst of completing this]
- environment [All environmental approvals completed]
- economic factors
- mining and geological factors [engineering consultants have been hired to completed the feasibility study]
- legal and governmental factors [Yukon government has been keen to get this mine going]

-------------------------------------------------

Getting conversion from inferred to measured and indicated is all about further drilling and documentation. OVR have already started to expand their resource as it is open at strike and depth. This is only the Andrew deposit. They are also drilling in the Darcy and Darin which also have discoveries.

The most important thing to note in a zinc mine is the metallurgy and what the company can get out in relation to beneficiation. They have already got high percentages of zinc and lead for this by using a DMS which is fairly common in the zinc industry.

The current economics already provide a 174 million undiscounted cashflow. I can assure you that the resource will be increased and the numbers will be much more higher. This is a mine in 2011-end. No doubt about it.
