Reviewer 2 Report
This is an interesting article, however, it requires technical language editing. I have shown some examples below.
34-37: Avoid one sentence paragraph.
79: “The purpose of this article was to show”,“…is to show”.
82: “vertical range of mineralization”, not sure what “vertical range” means here?
85: “Geological and structural position of Northeast Asia”: use “structural setting” instead of “position”.
100: “Location of research objects”: use “Location of study areas” or “research sites”.
146: “is given in the works”: use “is published by..”.
157: Please check the text in brackets.

Reviewer 3 Report
Savva et al. present a solid dataset of using typomorphism of native gold grains from various types of gold deposits in northeastern Russia as examples to show the importance of applying such a concept, especially to early stage of mineral exploration, to determine genesis of ore deposits and to predict depth of mineralization. They show that the fineness, trace element contents, and internal textures of the gold grains and their relationships to associated minerals differ in different deposits, and could be used as typomorphic features to differentiate geological settings of ore hosted rocks and mineralization depth. Thus, this study is suitable for the scope of the journal and useful in guiding gold exploration in the region and elsewhere. However, some problems listed below need addressed to improve clarification of this paper.
- Abstract needs rewritten to indicate why this study is needed to do, how it is done and what the major foundings are.
- What is ‘geological-industrial type (GIT)’? This needs an explanation, because this paper concentrates on typomorphic features of three GITs, i.e., 1) gold-arsenic-sulfide in black shale strata; 2) gold-quartz-veins in granitoids; and 3) gold-silver adularia in volcanogenic strata. It seems to mix up ore-hosted geological setting of gold deposits with readiness of ore metallurgical processes.
- Deposit descriptions need much shortened, and focused on ore geology including ore textures, mineral assemblages, and ore related alteration minerals. Too many geographic descriptions of each deposit evidenced in the section of ‘Regional Geological Setting and GITs of gold deposits’ lead to the distraction of core context. Is it possible to summarize the major characteristics of individual GIT (geological geological-industrial type)?
- What is the deposit of gold-quartz-porphyry in granitoids? Do you mean ‘gold-quartz-veins hosted in granitoids’? If so, change ‘porphyry’ to ‘veins’. Such deposits are likely intrusion-related gold deposits.
- The format of references and citation should be consistent with requirement of Minerals.

Reviewer 2 Report
Text has been improved, but would benefit from one more language edit.
Reviewer 3 Report
The revised version of this study has been greatly improved and addressed the problems identified in the original version. Few minors can be readily fixed via a thorough technical editing.
I would like see this paper be published in the journal because it is a good contribution to understanding of the various gold deposits using their typomorphic features of native gold minerals.
