To Mr. Isaac Hunter at Dukesfield                                              Newcas 31st. July 1772 


	I have examined the Assays of ore from Low Coalcleugh & Whitewood veins and find the former yields 8oz. 0 p[enny]w[eigh]t. 20 g[rain]s and the latter 7oz. 7 p[enny]w[eigh]t. 0 g[rain]s to a fother so you may refine them together & indeed it may be as well to smelt the ore together as you propose & I desire to know what the produce will be of 20 bings at the ore & Slag hearth of these two Sorts together.  I should be glad if you would at your leisure let me know what you reckon the Charge of Refining a Fother of Lead will be; computing the Waste at £14 a fother - that I may Compare with our Charge at Blaydon - I find by Mr Caleb Hunter that they have wrought of late some Ore at Allenheads at so much a Ton in Lead, wch. explains what you said about some of the Lead, included among the Wastes being better than Culling Ore Lead.  This Lead deserves to be Classed with the ore hearth Lead certainly and yet as they do not in the Grove Accot. charge the Mill with any Ore for or on Account of it We shall be deceiving ourselves about the produce of the Smeltings, especially if they raise any Quantity in this way - You may Consider about This against the next time we meet                                                                  I am etc   HR
