"These show cash of $176,214 before the April close of the $527,750 financing and $468,890 of exploration expenditures in the quarter."

The way it's worded i see $176,214 as of March 31. this is before the pp and before the expenditures. (+) $176,214 Before raising (+) $527,750 and before counting (-) expenses of $468,890. = $235,074

if we give CEO the benefit of the doubt and assume he is right and George just worded this weird and give drv 176,214 + 527,750 = $703,964.

As of Dec 31 $1,010,090. As of March 31 $176,214. = $833,376 cash burn in 3 months or $277,958 cash burn/month. 703,964 - 277,958 (April) - 277,958 (May) = $148,048.
