(although this does not pertain to nickel it does show you how many of the measurements can be converted. I just find it a useful reference.)

100 km = 62 miles so... 10 km = 6.2 miles

5 km = 3 miles

now you have 187 km from a referance point consisting of 640 hectares, where mineralization veins range from 2 to 80 cm are encountered in a zone of 250 x 1300 metres.

rules of thumb to remember

To convert into a system of numbers you can visualize, eg how far or how big is that. It is important to be able to visualize how far the property is from other significant properties or deposits and to have a mental picture of length and width of mineralized structure

metric units are used to describe zones of mineralizations

meter is close to 1 yard, 1000 meeters in a kilometer which equals 3,280 feet. length of almost 9 football fields in United States.

Trenches, drill plans and the length of drill holes and mineralized sections are reported in meters.

To visualize, for a non metric person who sees in feet... (ballpark) 1 meter M = 3 feet FT, 3 M = 10 Ft, 10 M = 33 FT

Smallest metric unit likely to encounter in mining is Centimeter CM, 1 inch = 2.54 CM. In mining reporting use of a CM never exceeds 100 which equals 1 meter (100CM)

A ruler with both scales will show 30.5CM in 1 FT..., this makes it simple to visualize.

Square Miles corresponding metric measurement scale is SQ Kilometer, acres would be Hectares

one hectare = 10,000 sq meters

one sq hectare = 100 x 100 meters (slightly less than area of 2 US football fields)

now ... 100 hectares = 1 sq kilometer and 1 sq kilometer measures 1000 x 1000 meters

1 hectare = 2.47 acres ... 640 acres = 1 sq mile (260 hectares = 1 SQ mile

A property having 1000 Hectares has slightly less than 4 SQ miles. Two field seasons of exploration would easily cover that area.

Valuations start with size and grades.

Base metals; calculating grade to it's metal content, into weight unit of rock, into dollar amount

Base metals are quoted and sold in the Avoirdupois system of weights (Used in United States) for commodities as base metals - coal, grain, and foodstuffs. Base metals are calculated in metric, reported as a percent of the avoirdupois ton (2000 pounds) or metric tonne (2,204.22 pounds) eg in US; ... 200 million tons of rock grading at One % copper would contain 20 LBs (pounds) copper in each ton of rock, or 4 billion pounds of copper in total.

2000 Lb in one avoirdupois ton x 0.01 grade = 20 lb copper/ton x 200,000,000 tons = 4 billion lbs copper in total

So with copper selling at $3.00 per lb each ton of rock has a gross metal value of $60.00 total deposit = gross metal value of $12 billion

Metric

200 million tonnes grading 1 % copper = each metric tonne of rock would contain 22.05 lbs of copper or 4.41 billion of contained pounds of copper ...eg (2,204.622 lbs in one metric tonne x 0.01 grade = 22.05 lbs copper per tonne x 200,000,000 tonnes = 4.41 billion lbs copper in total)

$3.00 per pound for copper each tonne of rock = gross metal value of $66.15/tonne total deposit would be $13.23 billion

This math gives you grade and size on which to base your judgement. When you have a idea of "contained gross metal value" you can get a good idea of whether it can be mined profitably. If a ballpark estimate of what it will cost to mine area is less than gross metal dollar value then a mine may be possible.

Knowing the gross metal value for the total deposit to figure out and assess the economic viability and most importantly the estimated stock price for company.
