Equivalent calculation
The contained metal equivalence
formula is based on the Sorby Hills
PFS including:
• Lead Price US$2,095/t;
• Silver Price US$21.1/oz;
•
•
Lead Equivalent Calculations
Silver recovery of 80.3% (weighted average of
oxide and fresh Ag recoveries); and
Silver Payability rate of 95%.
Silver Equivalent Calculations
Lead recovery of 93.3% (weighted average of
oxide and fresh Pb recoveries); and
• Lead Payability rate of 95%.
It is Pacifico's opinion that all elements
included in the metal equivalent calculation
have a reasonable potential to be
recovered and sold. The formula used to
calculate lead equivalent grade is:
Metal Eq (percent) = Gpri + (Gpri
[Σ; R;S; V; G; ]/(Rpri Spri V pri Gpri))
where R is the respective metallurgical
metal recovery rate, S is the respective
smelter return rate, V is metal price/tonne
or ounce, and G is the metal commodity
grade for the suite of potentially
recoverable commodities (i) relative to the
primary metal (pri).

Metal equivalents are highly dependent on the
metal prices used to derive the formula. Pacifico
notes that the metal equivalence method used
above is a simplified approach. The metal prices
are based on the PFS values adopted and do not
reflect the metal prices that a smelter would pay
for concentrate nor are any smelter penalties or
charges included in the calculation.
Owing to limited metallurgical data, zinc grades
are not included at this stage in the lead
equivalent grade calculation.
