    Agree

    Agree, it will be a question of whether we have sufficient grades of Li to get to a proper JORC

    Trenching/samples as assayed simply show that there is lithium there and the only excitement they bring is there might be lithium there. You need drilling to determine size, grade, depth and slope of the deposit. The idea is to move resource from the inferred category (note: at best this is all trenching and grab samples might get you to and that is at best assuming they are also doing some surveying as well) to the measured and indicated category and note only drilling (i.e. for Li definition usually DD or RC that does to depth - say 100 metres to 200 metres below surface) will get you there.

    I have put up this diagram before but to explain it, inferred at best is at best around 20% confidence level that a viable mine might will result, whilst measured and indicated is around 70% confidence level IMO. If you get to a measured and indicated resource you then do your PFS or bankable studies to move that resource to a proven and probable reserve category that underpins the mining development (at around 90% confidence level at the date of those studies). GPP needs to do some drilling after identifying its drilling targets through what it is doing now. Only measured and indicated resources can move to the probable and proven reserve category.
    All IMO
