Appendix II had a brief discussion of the tank losses in the 39th Panzer Regiment due to mines in our report on “The Military Consequences of a Complete Landmine Ban.” This is from http://www.dupuyinstitute.org/pdf/m-6mineban.pdf. It reads as follows:
APPENDIX II: THE 39th PANZER REGIMENT AT KURSK
Losses in the 39th Panzer Regiment at Kursk are confusing. On 4 July 1943 it had 200, and on 6 July 40 tanks, ready for action. But, a significant percentage of the tanks were broken down rather than combat losses. The regiment was attached to the Gross Deutschland Division during the battle. But it is uncertain whether the 20 tanks reported as lost to mines on 5 July were only from Gross Deutschland or included tanks of the 39th Panzer Regiment. We assume that it does not. The 39th Panzer Regiment was equipped with brand new Panther tanks that suffered from various teething problems which resulted in poor reliability. The number of Panthers available on the morning of 4 July is known (200), and the number that broke down during the march up on 4 July is
also known (two or, possibly, six). The next reliable strength report available is for the evening 6 July, when 40 tanks were reported operational. Some of the 158-tank shortfall was due to combat losses (including mines), but many were due to mechanical failure.
There are two reports of mine losses for the Panthers. One was a Quartermaster report of 76 tanks lost to date on 10 July. Four were total losses, 54 were mechanical losses, and 18 were “minor failures (with most caused by mines).” The other was an after action report submitted to the Office of the Inspector General of Armor Troops in August 1943 from the regiment. It reported that on the evening of 10 July there were 10 Panthers left “facing the enemy”, 25 total losses (including 23 hit and burned and 2 burned in the march to the front), 100 in the workshops (including 56 from gun damage and mines and 44 with technical problems). There were also 65 others being released or soon to be released from the repair facilities (cause of failure was not recorded in this report) for
return to the front. This report also stated that “about 40 Panthers were lost to mines in the first days…In one example a total loss resulted when flames penetrated the turret basket and ignited the stored ammunition…”
Since the quartermaster report for 10 July understates Panther losses at that time, and tended to lag behind the tank loss reports, it is assumed to be a partial report. The IG report giving 40 tanks lost to mines is probably closer to the truth.
For 5 July there are no actual reports of Panthers being lost to mines or being in minefields. Of the two battalions of the regiment, one put at least 30 Panthers across the Berezovyii ravine, and as a result, almost certainly took mine losses. Whether these were picked up in the Gross Deutschland report of 20 tanks lost is more difficult to determine. The other battalion did not get across the creek and probably suffered no losses to mines on 5 July.
The following day, they did encounter some mines, and also on 7 July and thereafter. If it is assumed that 18 of the 76 tanks reported as lost were all lost to mines, and that figure is used to account for all of the 158 estimated lost on 5 and 6 July (two them were accounted for on 4 July), then a total of 38 tanks were lost to mines. This is certainly the highest number that can be supported by the historical record. However, the actual number lost to mines may have been 10 or 20 tanks fewer.

There is a more extended discussion on tank losses due to mines at Kursk on pages 16-25. It covers the nine attacking German panzer and panzer grenadier divisions. Some of this made it into my first Kursk book.
