From First Majestic's Q3 production results:

The equivalent silver production for the quarter consisted of 719,399 ounces of silver representing a 35% decrease from the prior quarter, 1,518,271 pounds of lead representing a 24% decrease from the previous quarter, 536 ounces of gold representing an increase of 11% compared to the previous quarter. During the quarter the combined recoveries of silver at the three different mines showed a decrease from 70% to 67%. The overall average silver head grade in the quarter for the three mines decreased to 196 g/t of silver compared to the previous quarter of 230 g/t of silver.

The ore processed during the quarter at the Company's three operating silver mines; the La Parrilla Silver Mine, the San Martin Silver Mine and the La Encantada Silver Mine, amounted to 170,298 tonnes representing a 20% decrease over the previous quarter and an increase of 3% over the same quarter of 2007.

So they are processing ore with 196g/tonne silver. Based on their lead and gold production, silver is 84.5% of their metal value, so their Ag Equiv is about 7.45 oz/tonne. Compare that to ECU's news release today which averaged over 40 oz/tonne silver equiv.
