This should take place next year (Total/Cobalt drilling may de-risk this first). In a success case we see c80% upside to net asset value [NAV] and we think a de-risking brings Ophir into play as an M&A candidate."UBS's NAV forecasts has been reduced from 835p to 805p due to the smaller-than-expected discovery. With the price target being set at a 10% discount to NAV for "country risk", it comes down to 725p, from 740p previously. A 'buy' recommendation has been maintained on the stock.BC
