Brown Argus or Northern Brown Argus ssp salmacis? Yorkshire

Your collective help please
I was in in the Yorkshire Dales near Grassington and saw a number of Brown Argus sp in a grassy area at 260m altitude below some big limestone scree slopes. They were very active but I managed to get a few shots of one individual (attached)
There appears to be a lot of white on the leading forewing spot on the underwing but otherwise I am struggling to resolve the ID either way
I know that this site would be at the very southern limit of NBA distribution in N England but am also aware of remaining key strongholds for this species in the Ribblesdale/Ingleborough and Wharfedale/Littondale areas of the National Park - so this sighting would fit that known distribution
Can anyone help me with a conclusive ID on this individual please, together with any pointers for the distinguishing features? Many thanks
