From WIPO FAQ.
Instead of speculating when we would see something official about the SiLeach patent I looked at the WIPO FAQ.
Summary
Together with the search report, the ISA prepares a written opinion on patentability, which will give you a detailed analysis of the potential patentability of your invention. WIPO publishes the international application shortly after the expiration of 18 months from the priority date
Until international publication, no third party is allowed access to your international application unless you as applicant request or authorize it. When international publication occurs, certain documents in the international application file are made available on PATENTSCOPE together with the published international application.
SiLeach has a priority date of 9 February 2016, so this data will be available to anyone shortly after 9 August 2017.
More details below.
11) What does it mean to “claim priority” of an earlier patent application?
Generally, patent applicants who wish to protect their invention in more than one country usually first file a national or regional patent application with their national or regional patent Office, and within 12 months from the filing date of that first application (a time limit set in the Paris Convention, see Question 2), they file their international application under the PCT.
The effect of claiming the priority of an earlier patent application is that a patent shall not be invalidated by reasons of any acts accomplished in the interval, such as another filing, the publication or sale of the invention.
15) What is an international search report?

The international search report consists mainly of a listing of references to published patent documents and technical journal articles which might affect the patentability of the invention disclosed in the international application. The report contains indications for each of the documents listed as to their possible relevance to the critical patentability questions of novelty and inventive step (non-obviousness). Together with the search report, the ISA prepares a written opinion on patentability, which will give you a detailed analysis of the potential patentability of your invention (see Question 18). The international search report and the written opinion are sent to you by the ISA.
21) What does international publication under the PCT consist of?

WIPO publishes the international application shortly after the expiration of 18 months from the priority date (if it has not been withdrawn earlier), together with the international search report. PCT international applications are published online on PATENTSCOPE, a powerful, fully searchable database with flexible, multilingual interfaces and translation tools to assist users and the public in understanding the content of published applications.
22) Can third parties access documents contained in the file of the international application? If so, when?

Until international publication (18 months after the priority date), no third party is allowed access to your international application unless you as applicant request or authorize it. If you wish to withdraw your application (and you do so before international publication), international publication does not take place and, as a consequence, no access by third parties is permitted. However, when international publication occurs, certain documents in the international application file are made available on PATENTSCOPE together with the published international application, for example, the written opinion of the ISA and any informal comments on the written opinion.
