Frank, I suggest you read the rest of my post. You might understand what I am talking about.

Alamos begins commercial production at Arequipa

Thu 14 Jan 99 News Release
Mr. Francis O'Kelly reports
The company has commenced the first stage of commercial exploitation of its
100 per cent owned Arequipa M property near Ruaraz in the Ancash district
of Peru. The mine and surrounding concessions host a series of
northwest-southeast mesothemal veins. The principal Arequipa vein consists
of two discrete assemblages: (1) a polymetallic vein containing silver,
zinc, lead, copper and minor values of gold and (2) an arsenopyiite vein
containing significant precious metal values. A north-south vein (veta
Mabel) branches from the Arequipa vein and is traced over 300 metres on
surface and is observed in level 6 of the underground workings. Within
close proximity, there is an east-west trending manto dipping at 20 degrees
with thickness 80 centimetres to 2.0 metres. To the west of the concession
there are observed twin veins (vetas oriental) trending northwest to
southeast parallel to the Arequipa vein.
The initial production is from the main polymetallic vein at level 14, the
uppermost level of the mine. The ore type is primarily galena with a high
content of silver. The in-situ grade reports 43.40 per cent Pb and 2,120
grams per tonne Ag.
Specimen grade ore (more than 3,500 grams per tonne Ag) is being separated
for direct shipment to an as yet undetermined smelter. The remaining
high-grade ore is trucked 50 kilometres to the Mesapata mill south of
Huaraz for concentration. The 200 tpd plant is leased from the University
of Huaraz. The first milling campaign will commence at the end of January
and arrangements have been made for the sale of the ore concentrates.
Production at the mine is currently limited to 50 tonnes per day, which is
the capacity of the overhead tramway for transportation of ore to level 6.
The mine road connecting to this level is now fully operational and can
accommodate trucks up to a capacity of 25 tons.
Underground development is focused on the extension of drifts on level 7
and level 14 and internal connection of ore passes to the level 6.
Completion by mid-year will facilitate a substantial expansion in mining
capacity per day. The exploration drifts report mostly continuous
arsenopyrite and polymetallic mineralization in contiguous vein systems.
The 14th drift is currently at 105 metres and drift 7 at 197 metres. Both
report sphalerite (zinc) and galena (lead) in the face with a vein width
averaging 50 centimetres.
Systematic sampling of the Arequipa vein was completed last November. The
resource assessment focused on the section of the mine above level 6 to the
uppermost exposure of the vein at the peak of the mountain. This represents
68 per cent of the potential resources above level 6 and 21 per cent of the
total resources for the Arequipa vein. The Mabel vein and manto were not
included in the measurement. The sampling results indicate an arsenopyrite
resource of 200,000 tonnes grading 12 grams per tonne Au with an average
vein width of 0.82 of a metre. A total of 70,000 tonnes of the resource is
classified in the proven/probable category. The calculated resources are
higher in tonnage and lower in tenor than previously reported, but

resulting in approximately the same metal content.
MDI laboratory of Denver, Colorado has tested the differential flotation of
copper and arsenopyrites, resulting in the production of a high-grade
Cu/Au/Ag concentrate and an arsenopyrite/pyrite concentrate amenable to
cyanide leaching. The preliminary testwork produced a copper concentrate
assaying 22.8 per cent Cu, 1,075 grams per tonne Au and 2,480 grams per
tonne Ag.
