Ann: Increase in Deflector Mineral Resource and Ore Reserve, page-24

And this 15% increase is of the average reserve grade. What's being added to is actually much better than 15% as the Deflector South West (DSW) lodes only represent 35% of the total reserve. From the announcement:

“DSW is interpreted as an extension of the high grade gold/copper Western lodes which have higher gold and copper tenor than the Contact and Central lode system...";

"The mineral resource remains open along strike to the south. Recently reported underground drilling targeting this area returned significant results, including DFUG192 (7.4m @ 98.7 g/t gold and 11.1% copper), which is the southernmost underground exploration hole drilled at Deflector to date..."

Good chance this will only get better... furthermore, not only grade but recoveries will improve following the plant upgrade.
