Dear Missionnaire,

Approved.

To prevent operational disruption in June - July 2026, the Technical Standards Committee approves the emergency procurement of 100 demolition hammers (JEISHIDA G125GPT) with corresponding spare parts, as a temporary bridging measure.

Conditions:

*       This approval is limited to the June - July 2026 supply gap and does not replace the standard ANSI/TSC approval process for long-term standardization.
*       Procurement to ensure the supply includes critical spares, and confirms compatibility/fit with our operating needs, plus standard warranty and after-sales support.
*       Given the 1500 rpm vs 2000 rpm difference, these units should be prioritized for medium-hard rock applications as proposed.

Procurement may proceed immediately.

Best regards,

Regis NGENZI

Subject: Request for Approval: Alternative Demolition Hammer Brand to Prevent Operational Disruption in the end of Quarter 2 of 2026

Dear Chaiman of Standard committee,

I am writing to formally request urgent approval to procure an alternative brand of demolition hammers as an emergency measure, in order to avoid a disruption to ongoing mining operations.

Background:

We are running out jackhammers (demolition hammers) and spare parts, previous order had quality issue, we are waiting a new order of 200 Jack hammers that will  arrive in our stock around January 15th , previous order experience: We received 400 Jack hammers in our stock on ….. we close year  (December 2005) with only 16 JHO.

We placed an order of Jack hammers on August 14th ,  production was completed on 30th October , there are now at Mombasa we might receive them around 15th January, a lead time of 5 months.

We want to place another order now, unfortunately the production team will be interrupted by Chinese new year holidays that will start on February 17th, most companies will resume operation after March 5th , eventually we may receive other jackhammers in end July to August given the lead-time of 5th months as described above.

Given the previous experience as mentioned above the 200Jack hammers that will arrive in June will be consumed Mid June, End June to August will not have any solution unless buying local at double or triple cost.

To bridge this critical supply gap, we propose the temporary procurement of an alternative brand (JEISHIDA)  for 100 Jackhammers hammer( with spare parts) that:

*       Is readily available now
*       Can be shipped immediately
*       Meets operational and technical requirements comparable to our existing approved model( see below specs ): There is a slight difference on input speed ( Existing one have 2,000 rotations per min while the alternative model has 1,500 rpm, remaining specs are the same) we may use them in medium hard rocks.

I’m seeking your approval  for bridging the gap we will have in June to July 2026 as mentioned above and proceed with ANSI process later.

If you have any questions please contact me and procurement team( Group or site) we had a meeting today regarding this matter.

Effetool105 : Existing brand specifications                                                                                                                                Jeishida: G125GPT
