> As a layman, I have trouble drawing conclusions about the safety/toxicity of these numbers,
Your numbers
0.36 Copper
0.29 Lead
0.08 Silver
31.1 Tin
3.93 Zinc
Morse reported the following values in NYS honeys (ppm)
copper (0.13 to 3.3)
lead (0.03 to 0.28)
silver (0.002 to 0.094)
tin (0.002 to 7.5)
zinc (0.18 to 5.6)

I am surprised they would return these numbers to you with no guidance.
The level of tin in your sample is high but not over the limit (no surprise). "No adverse effects were noted in 9 volunteers fed a C-ration diet consisting of canned fruits and meats which had been stored for 20 months at 37°C. The tin content in the food ranged from 254 to 538 ppm." (Calloway & McMullen, 1966)
The lead looks like a deal breaker to me. Your honey has almost 3x that level and is as high as the highest level reported by Morse.
In the past, recommended lead tolerance was higher, a level of .3 mg/kg, was recommended by FAO/WHO/1984. But it has been lowered due to concerns about children. FDA recommends that lead levels in candy products likely to be consumed frequently by small children not exceed 0.1 ppm.
(1 ppm = 1 mg/kg )
