Bushkid if its really good I'll say mid 30s
For price action like that it would have to be a luke warm announcement at best. 22-35c is worth about 9 million in market cap. Peanuts by any means!. Look for a minimum 50c would be my bet if it's a good announcement. From memory we have resitance in the 50's, 70's and of course the all time high.
