Although it´s still early stages and XBR hasn´t even started production, it´s good to hear that a plant expansion to possibly 750 tpd is already planned for.
Have a look at the video again, where you can see, that they already built the foundation for another 500tpd ball mill next to the existing 250tpd ball mill.

Once they start production and get cash flow positive, the biggest step forward will be mill expansion. This will be a really big step, cash flow wise, if they manage to get a 500 tpd mill next to the existing 250 tpd mill, as can be seen on page 21 of the actual company presentation:

Even at 3gpt Gold and NO Silver credits (!), the 49% share of cash flow for Excalibur would increase from about $5M to around $14M annually.
This is what Tim Gallagher expressed in a mail regarding these expansion plans and average grade projections:
"... but the 250 tpd plan is to mine a million tons over the next 12 years with a target of up to 5 million tons with plant expansion and a District potential of perhaps 20 million tons. You can do the math if we average 3 grams Au and 1 ounce of Ag. Hopefully, we hit bonanzas which will double or triple the average grade."
